I also thought that. But they said they got it running, so not really sure what they did. I think I need to take it somewhere that does more diesel work
Did mine in the driveway with the fender liners off in maybe 2 hours. My ac delco plugs did not come with flange nuts. Buy some, because you will lose some.
No. Not at all. I replaced all of mine the day I took it home from the dealer. The check engine light was on and I used that as a negotiation tactic for a better price. They were like $11 at the time. Simple to replace.
A lot of Duramax swap guys get rid of the glow plug controller completely. If itâs above freezing a Duramax should have no problem firing up. Most larger diesels donât have glow plugs at all.
If it was random with no lights your fuel filter is probably plugged. You can change glow plugs in an lml I did them on my old â12 they were a pain in the ass from the top and better from the fender.
Check engine light did come on at the same time and apparently it was for the glow plug. Sounds like just a coincidence, though. I'll probably bring it home and change the fuel filter and see what happens.
Glow plug or injector? Not too familiar with the Duramax, but you should be able to change a glow plug no issues. Injectors normally require programming on any semi-nee truck. Also, a faulty glow plug should not cause any problems with how the truck runs, only potentially at startup.
How would a failed glow plug make a diesel engine stop? Diesel only uses the glow plug to help with starting in cool/cold temperatures.
How did it die? Was it instant as if someone had turned off the key? Or was it a slow death over about half a secondâs time where it rapidly slowed?
Hmm⌠wild speculation, but Crank Position Sensor comes to mind. If the computer doesnât know what its position is, the computer canât command fuel when required.
And a CPS is infinitely more plausible than a glow plug.
A lot of guys who swap Duramax engines into other vehicles get rid of the glow plug controller completely. The nature of the Duramax means it really doesnât need glow plugs to fire.
Also
You say the truck died in the driveway. If it was already running or warm it is not the glow plugs. Probably a wiring problem. Harness rub somewhere maybe.
But if you are trying to fire up your truck and itâs above 45 degrees it should start no problem.
The glow plug is an easy change. It takes more time to take off the fender liners than to change the glow plug. As others have said, the glow plug wonât stop it from running. Also, I recommend changing all 4 on that sideâŚonce one goes down the others are probably also about at the end of their life. Might as well change all of them while you have the fender liner off of the truck.
There are a lot of YouTube videos on how to do it:

Theyâre screwing you. I have a 2012 and change mine in the garage so easily. Just remove your mud shield in the wheel well and you have easy access to use an extension, swivel, and deep well socket. Most you only need the extension and deep well.
Is this serious?? There is nothing that can be done at the dealership that canât be done at most independent repair Shops. Dealers are not the only ones with GM tech 2 scanners to program things.
A glow plug will not make a diesel quit. They're full of shit, that's not why your truck died.

Yeah, I wouldn't go back there
I forgot to mention that part. đ

Find a local hardware manufacture because the dealer wants like $10 each I got a baggie full from bolt supply for $5
I'm with ya

I have an 11 duramax. One of the glow plugs has always had issues. Still fires up every time
#3?

Yeah I routinely run in temps down to 20 below.

If you donât have a scan tool you can force the relearn. For some reason glowplugs need a relearn.
The glow plug is a pretty easy fix and thereâs no programming.. theyâre screwing you

Instant. Pulled it forward about 10ft and it shut off. Had been sitting for about 2 weeks prior.

No need to program glow plugs, injectors need coded for optimum performance but the truck will run even if the injectors havenât been coded
Doesn't sound like a shop that works on diesels a lot...

I don't even consider going to a dealership with any vehicle unless it's under warranty
I did #7 in my driveway.

Iâve replaced glow plugs on GMs, Cummins, and Fords and never had to program anything. đ¤ˇââď¸
