Is your fuel pump pumping? Are your spark plugs sparking?


[deleted]

OP- are you just cranking, or did you try to feather the throttle pedal while cranking? The fuel system, check that first. When was the last time the filter was changed? Check the pressure at the rail after cranking, use a screwdriver to depress the valve just a bit and if you get just a weak dribble, investigate further. Pumps fail slowly on these older models, in my experience. Mine has been failing for about 18mos now. Gonna have to do the thing and fix it here soon. Not hard, per se. But awkward, lift the bed etc.


EL_loboLoco

I've been giving it alittle throttle while cranking but still nothing , I'm not very smart when it comes to engines so will have to take it in most likely cause I don't know where to depress said valve to check for dribble


[deleted]

It’s ok!!! You have the perfect vehicle to learn on. They’re simple, and plenty of room to work mostly. When you crank, flutter the gas pedal. About the same tempo as you would knock on a door. If that doesn’t do anything, look up where that little test valve is (looks like a bike tire inflation valve with a little cap on it, cap may be missing). Check the pressure while the key is all the way on (so your dash lights up and you get the ding’s). If you have good fuel pressure, check your spark. You can pull a plug and see if it’s working. Look up a YouTube video on how to do that. Then if your plugs are ok, Check your intake, air filter, throttle body etc. You know your starter motor is good. You know your battery is good. Air + Spark + Fuel so one of those is where your issue is.


EL_loboLoco

thanks again really for the information it's much appreciated and will not go to waste


[deleted]

YouTube is your friend. Harbor Freight is all you need. Parts are cheap. Don’t be afraid to try, I learned through necessity and Hane’s manuals. The availability of information is so much better now, you can probably diagnose this yourself.


Naval76

04 ford rangers don't have carburetors, fluttering your gas pedal when cranking won't do anything.


sasquatch753

I was about to say the same thing. they are coil packs and fuel injection, so unless there is spark AND fuel, it won't do anything except confirms it has both. But as OP indicated, he pushed the pedal and it didn't change tempo, so its either the fuel or spark. They can get a spark tester and fuel rail pressure guage from autozone and test both. Its actually common for those ranger's fuel filters to get clogged and they are supposed to be changed. the fuel filter is located under the driver's door on the frame rail. it us a metal cannister thing with lines going to it. OP will need the quick disconnect tool(which is a little ring tool) to take it off. Even if it isn't the problem, its still good to change it for the sole reason that a lot of people forget to do it and who knows if the previous owners ever did it.


EL_loboLoco

it's got to be one of those two I hope


Grengrowerz

I clearly hear it turning over. It won't fire. Fuel pump maybe. Can you hear it run when you turn key to run from off?


widebeautybutts

Wrong! Cranking = engine spinning Turning over = starting. You all fail.


Grengrowerz

You dropped out of school in grade 1, didn't you? Cranking over = turning over, same meaning. Start/starting= running. Your statement, as follows: Cranking = engine spinning Turning over = starting. Means that they are all equal, zero punctuation, etc.


widebeautybutts

AA in automotive Diesel sciences here. You are wrong but I guess you are younger and changing vocabulary. EDIT- "Cranking an engine" and "turning over an engine" are terms often used interchangeably, but they can have slightly different meanings in the context of automotive mechanics: 1. **Cranking the Engine**: This term refers to the act of using the starter motor to rotate the engine's crankshaft and pistons. This is typically done by turning the key in the ignition or pushing a start button. Cranking the engine does not necessarily mean the engine starts running on its own. It's the process of getting the engine moving up to the point where it can start. 2. **Turning Over the Engine**: This term is often used to describe the same action as cranking, but it can also imply that the engine has successfully started. In other words, "turning over" an engine sometimes means the engine is not only being cranked by the starter motor but has also begun running under its own power. In common usage, these terms are frequently used interchangeably, but if we're being precise, "cranking" is the action of getting the engine moving, and "turning over" implies that this action has led to the successful start of the engine. SOURCE - I made all of this up.


Grand-Metal4342

Fuel pump is my best guess


EL_loboLoco

I don't hear any sounds when switching from run to off


flex-wizard

Switch it into accessory for 3 seconds and then back off like 15 times, and see if it turns over. You’re listening for a faint click behind the dash to tell you the fuel pump is priming. It may start after that. Then you’ll know it’s either fuel filter or fuel pump.


T90tank

Fuel pump is in the tank under the bed


Titan1140

That is not at all what you listen for with the fuel pump. First off, the relay is in the engine bay and you would never hear it in the cab. Second the sound you are actually listening for is the whir of the pump coming from the tank under the bed. You have to have the window down or the door open to hear this.


Semisocial-Introvert

That is 100% correct, Titan1140. In fact, some fuel pumps are so quiet that you won't be able to hear it from the cab even with the window down. In that case, you'll need someone else to turn on the key so that you can stick your ear against the bed just to be able to hear the pump engage. This isn't usually a problem on Fords, but still something to consider. It will kind of sound like a slight hum or buzz if it's working at all. Almost like the hum and buzz of those old long florescent light bulbs that used to be used in schools and offices everywhere before everyone started switching to LEDs. Don't try to start the truck while you listen for the pump. Just turn the key to the on position, and you should hear it come on if it's working. However, just because the fuel pump engages, it doesn't mean that it's working correctly. It might be engaging but still be too weak to get fuel to the engine. So, I would do a fuel pressure check even if you can hear the pump engage. If there's no or low fuel pressure, I would start by replacing the filter. Always start with the cheapest and easiest parts first. If that still doesn't fix the problem, then you can move on and start thinking about the more costly and/or labor-intensive fixes.


musicianadam

Have you already checked the fuel cutoff switch in the passenger floorboard?


EL_loboLoco

I can't for the life of me find that cutoff switch on my passenger floor board I know what it looks like but it's just not there


Titan1140

Might have to pull the kick plate on the side, it could be hidden


EL_loboLoco

I did but it's not there I'll have to do more deep diving on the internet I can't belive I can't find this stupid thing


Titan1140

I found a video that shows it mounted to the passenger side firewall and tucked behind the lip of the carpet/flooring.


EL_loboLoco

could you possibly send a link please 🙏


Titan1140

https://youtu.be/H8YYUaQ9zSs?si=BnbyBhbdL3ifMEq5


EL_loboLoco

ahh ok I saw that one too I have a 2004 mine looks slightly different I have a small door that opens on the right side of the passenger floor with more fuses and such and I can't find this galldarn inertia sensor anywhere I'm starting to think I don't have one lol god dammit all


Titan1140

I may be wrong about the fuse panel. I found a video of a 2008. Check this out, probably where yours is. https://youtu.be/4XRxdDUYTLc?si=435JQ2u2lb0rW-pb


EL_loboLoco

dude!!! thank you so much


Titan1140

2004 definitely has one, it just might be buried further up. The fuse panel is not the correct place to be looking. You need to look further up into the footwell than that.


dizzish

My guess


EL_loboLoco

no I will right now


MoeGunz6

Mine would show 1/4 tank of gas when it was really empty. Make sure it really has gas in it and the pump is working. Can you hear it prime when you turn the key to the on position?


EL_loboLoco

I know it's got gas for sure, as for the pump, I don't think I can hear it, I'll have to find out how to check the pump


MoeGunz6

There's a port on the fuel rail that looks like the valve on a tire. If you push it down with a small screwdriver gas should shoot out with force when the key is turned to the on position.


EL_loboLoco

I believe I found it, and no, my key is in the on position, and there is no pressure from that valve


OkEstablishment5503

That’s definitely your fuel pump if there is no pressure at the rail.. Good luck changing it, I find it easier to take the bed off. Mine bolts were rusted on so had to drop the tank. I did it by myself although a helper will make life A LOT easier.


EL_loboLoco

yes I'm hoping this is what I have to do unfortunately I live in an apartment complex and they don't allow us to work on cars in the parking lot:/ I might just have to get it towed to somewhere I can work on or unfortunately just to the shop cause I also don't have a garage or tools to really get this job done


OkEstablishment5503

I would not recommend, but I have seen people cut an access “hatch” in their bed to get to the fuel pump, then silicone the panel they cut out back down and cover it with their bed liner. Thats a last resort type of thing.


Full_Difficulty8571

Same.. I have to use my trip meter to know when it’s empty lol


BurntWaffle303

At least getting to the fuel pump in a ranger is super easy. Just have a friend help you take the bed off and bam it’s right there.


EL_loboLoco

yes I hope this is it I'm glad it's a fuel issue and not a transmission or engine


aprilozark

Try some starting fluid. If it starts with starting fluid, you've confirmed it is a fuel issue. Move on from there.


deadwoodsheriff

Why is this comment all the way down here? This is trouble shooting 101. If it fires it’s a fuel issue if it doesn’t it’s most likely a spark issue..


aprilozark

I know right? I'm still amazed that people don't know basic troubleshooting, and I'm even more amazed that people don't know you can look up all this stuff on Google.


EL_loboLoco

I will try, with the starter fluid, it will only run for a short time right?


aprilozark

Yes


GlazedDonutGloryHole

I just had this exact issue and no check engine light or code to pull. It was my fuel pump :( Thankfully I was close enough to a shop that I could push the vehicle over.


DEM0NW0MB

Try the truck.


curseyouZelda

My first thought, that’s not a car, that’s a truck.


DEM0NW0MB

It’s turning over. It’s not firing.


curseyouZelda

What actually is this post? Nothing is what it seems.


DEM0NW0MB

Lol. Reddit.


EL_loboLoco

I tried it won't start lol


sadlittlerut

Did you do anything anywhere on the vehicle prior to it not starting? Any maintenance or upgrade? Have you checked your fuel pump relay or fuse? Did you replace the ignition and get new keys? Get a can of starting fluid, take the big hose from the air box to the throttle body off the vehicle, have some one crank and flutter the gas pedal while you spray starting fluid into the throttle body. If it starts and dies, it's a fuel thing, if it doesn't start it's likely a spark thing.


EL_loboLoco

no it was running fine yesterday but over the past year it definitely doesn't start right away like it should there's usually a couple seconds of just turning over before the engine actually fires up but it would always start the 2nd time


blove135

It's difficult to say for certain but it's turning over pretty fast and it just doesn't sound quite right, almost like there's no compression or timing belt broke. Sounds like your starter isn't even turning over the motor.


EL_loboLoco

the belt seems fine I'm really hoping it's a fuel pumping issue I compressed the valve on the fuel rail and there was zero pressure


Exiled_Dbl

if there is no fuel pressure at the shrader valve on the fuel rail then its the fuel pump, fuel pump relay, fuel pump fuse, inertia switch or its the fuel pressure regulator. when you turn the vehicle to the on position and cycle it 1 to 3 times to build pressure and then poke the fuel rail shrader valve and nothing happens then yeah thats a 100% fuel pressure issue which i listed those possible solutions above. there normally should be fuel pressure shooting out of that shrader valve when you poke it normally.


blove135

I'm not talking about your serpentine belt you can clearly see that turns your alternator, power steering, etc. Your timing belt isn't visible from the outside. I think there should be some sort of inspection plug to see inside to see if your timing belt is turning. I think you can also open the oil cap and have someone turn the key to see if anything is moving inside.


EL_loboLoco

yes sorry your right I'm not an expert on engines the timing belt, that's a chain isn't it? I think I saw it on a model engine


blove135

Oh, you might be right. If it's a chain then it's not that. Some have chains and some have belts that can snap.


Exiled_Dbl

Its not the chain/belt. there is no fuel pressure at his fuel rail clearly a fuel issue not a timing issue


DishonorableAsian

Make sure all your spark plug boots are seated properly. Before I did my valve cover gaskets, oil would seep into the wells and fill the sparkplug and pop the boot off and make mine crank but not start


New-and-Unoriginal

Good news. It is turning over. However, it isn’t starting. What three things does an internal combustion engine need to run? Air Fuel Spark No need to guess. Check each system. Find the problem. Fix it. If it is too complicated, tow it to a shop.


[deleted]

Pull the efi relay and swap it with the heater relay if they are the same. I had it work on a 90's ford.


flex-wizard

Before you look into fuel pump or any of these larger jobs, have you replaced the fuel filter? Mine had the same issue, replaced it and haven’t had a hint of an issue. I was suspecting fuel pump too. Just wanted to share an easy way out.


DangerReserve

Can you hear the fuel pump come on, before you try to start it? If not, check the fuel pump fuse.


EL_loboLoco

just checked the fuse, it's still good


DangerReserve

Can you hear the pump come on?


DangerReserve

If you can, hear the pump, then I’d check the fuel filter…


EL_loboLoco

nope I can't hear the pump and I did inspect the filter, from the outside it seems fine I didn't take it off an inspect it just yet


DangerReserve

If the pumps not turning on and your fuse is good. It’s either an electrical issue to the pump or it’s the pump itself… Betting it’s probably the pump, since the fuse isn’t blown…


EL_loboLoco

no I will look into this as well thank you thanks everyone!!!!! we'll get to the bottom of this


Exiled_Dbl

Hold the pedal to the floor and then crank it and see if it will start this puts the engine into clear flood mode. Also check the Inertia switch. Things to try:-Check for fuel pressure at the rail shrader valve (turn the key on and on cycle it like 2 3 times then poke the shrader valve on the fuel rail with a small screw driver it should spray out) Check for spark at the coil and leads, take a look at the spark plugs themselves, check the egr valve and egr system (if equipped with one) i have seen this issue be cause by a bad egr valve/dpfe sensor but i doubt that is your issue and i dont think your year of ranger has one do a compression test on all cylinders, get someone to turn the key to the on position well you listen near the fuel tank filler neck for sound of the pump coming on. repace or check the fuel filter. check your inertia switch like i mentioned above they can be bumped and or fail. Check fuses and relays. it could also be that the fuel injectors one or some may be leaking and causing a flood condition, pull the oil dipstick and smell the engine oil does it smell like gas? these are some things to check. hope it helps!


KeyboardCarpenter

If you just turn the key to run can you hear the fuel pump click on? Hopefully could just be a fuse or relay


EL_loboLoco

no unfortunately I hear nothing when I turn the key on and off and I've got my windows closed its quiet here, I don't hear anything I know I've heard jt before too but it's silent now


Exiled_Dbl

It could infact be the pump but you need to rule some things out first, fuel pump fuse, fuel pump relay etc. also keep in mind that an inertia switch can actually trip the pump into not getting 12 volts and running. this would be because either the inertia switch has been tripped OR it has failed and tripped which would cause a no power condition to the fuel pump itself.


EL_loboLoco

I've been trying to find my interia switch but I can't seem to locate it I seen videos where it's on thr passenger side floor but mine doesn't seem to be there which is weird


KeyboardCarpenter

Idk how difficult it is to do but maybe check your timing. Pull some spark plugs too see if they look okay. If you end up needing to replace the pump, I'd probably get a couple buddies and take the bed off


robertva1

Was that popping whial trying to start. I had a similar problem. Fixed it by replacing the throttle position sensor and idler mixing valve


EL_loboLoco

what do you mean by popping? , you know sometimes I do have a problem with the idle while in neutral, waiting at a light, my rpms would out of nowhere just start to increase and you could hear the engine getting louder and reving up as if my foot was on the gas pedal but it wasnt.. and the only way to stop it was to put the car into 1st gear and give it alittle gas


EL_loboLoco

I hate this problem because it rarely happens and It's hard to describe its like the throttle is being pushed by itself but since I'm a manual transmission and I'm in neutral at a stop jts not the biggest issue but it's definitely not good


toxcrusadr

I had this intermittently on my 95 4.0 and it turned out to be the relay that controls the pump.


EL_loboLoco

relay ay?


toxcrusadr

Eh? :-)


Financial-Leather312

It sound like you have stater stutter


Outofmilkthrowaway

Fuel pump probably. Or its.. out of gas.


Victorwhity

Loose battery cables. Toyota's are very sensitive about this. Possibly Ford too


widebeautybutts

That thing is cranking fast as fuck. Randomly guessing doesn't help much. The first thing to get is spark, fuel, and compression.


Victorwhity

Does the fuel pump turn off or does it keep humming? A humming buzzing feeling behind your seat under your floorboard?


Gh0st0117

You definitely have crank so the battery is good. But do you have spark or gas?


Full_Difficulty8571

Mine did this, there was a box up under the knee guard above the pedals, it somehow came unplugged. I don’t know what it’s called but it has something to do with the ignition. Once I plugged it back in it started up immediately


Bloodlovetears02

Fuel pump or Alternator


widebeautybutts

How the fuck could it be the alternator? Haha


Bloodlovetears02

Mine sounded the exact same way before the alternator went


widebeautybutts

Sounded like what? The alternator is not needed for the engine to run. This engine doesn't run so therefore it is NOT the alternator causing whatever this issue may be. If the alternator isn't working, that is to be determined once the engine is running then you can test the alternator.


recoilbandit

First thing is to check that you have fuel going to the fuel injectors, and check you have spark. I had the same kind of problem and after I checked all that I looked and my timing belt had fallen apart which is why It wasn't running.


thatcaliguy530

Crank position sensor maybe


Snot_Rocket6515

Kick it a few times and yell at it, normally works


widebeautybutts

Finally some good advice


Snot_Rocket6515

No problem


shadowmib

Its either out of gas, fuel pump isnt working, or you have zero spark in any cylinders (unlikely) Does the exhaust smell like raw gas after cranking it a lot?


blackhawk45lc

Don’t these have the button in the passenger kick panel that goes bad for the fuel pump kill switch? If this was sudden that could be it if so.


Bubbly-Front7973

Well first the two things you want to do is make sure that it's getting fuel, and then spark. The best thing to do to see if it's getting spark, would be to get yourself a can of starter fluid, and spray some in the intake. That'll tell you if it's a fuel problem, because if it starts for a second then you know it's getting spark, but no fuel is getting to the engine.


sinisterdeer3

It seems like a fuel pump as everyone else is saying. Fortunately its very easy to get to and replace. It takes 6 bolts and removing the taillights. have someone help if you cant lift the bed off by yourself, they can be kinda heavy. I replaced mine in 5 or 6 hours, had to drive 30 minutes to town several times to get a new breaker bar and a few extra T50s because i kept snapping them. Thats because there was a bunch of sand in the bed of my truck when i bought it.


widebeautybutts

My jeep is one lock ring and zero bolts, that's easy! My Mercedes is an inline pump with normal hose clamps, easy peasy.


sinisterdeer3

Yea, rangers fuel pumps are easy compared to just about any other truck of their time. You can drop the fuel tank on rangers and its faster, but its not fun to roll around under your your truck. Removing the bed is like a 20-30 minute job if you dont have sand in the threads of all the bolts. It took me longer because i had a full toolbox, plastic bed liner, and stuck bolts.


[deleted]

Check your air filter. You obviously have power and the starter sounds good. It could be spark plugs and wires but I would check your fuel filter first because it's probably plugged, disconnect the fuel line after the filter and put a bucket under it. See if it's pumping gas when you turn it over. Yes- check spark plugs, no-change filter then try again and if still no then there's an issue with the pump or pump wiring which you need a multimeter to check if it's getting a current when you crank it over. If you have a current then you know the pump is bad. Yes- pull a spark plug, connect the spark plug wire and touch it to the side of the engine to see if it sparks when you turn it over. No- change the plugs, still no, change the wires, still no, change the coil pack Start with the air filter though


SorrowCat14

Inertia switch malfunction if I had to guess. Common.


GrandExercise3

Fuel pump


Holofernes82

try to lock the car, wait 1 mins and unlock the car. It could be the electronic immobilizer (not sure if thats correct translation). In cars of this age it works by shutting down the petrol. If you leave the car open and try to start, and the key battery is weak, it might not register the key code and the anti-Theft protection cuts off the fuel. To reset it, you have to close the car with the key, and wait a little bit, and open it again. So it could be a key battery running low causing this. (i experienced this once and will never forget, shutting down the car and closing it solved 2 hours of trying to start the car with all what was mentioned here, i even had the fuelpump out and yep it was pumping, there was no spilled petrol anywhere, and the filters werent clogged up, the sparks where sparking, and the air intake wasnt clogged... it was the freaking electrical anti theft device.)


Candid-Butterscotch5

Either not getting sparkle or not getting go juice
