Duramax experts???

[Roc87]

My work truck (GMC Duramax C5500 w/ 18' box) left me last Wednesday morning, crank and crank but no start, took the local dealership 3 days to find the problem of the injection module, then I went to pick it up and the thing wouldn't start for me, so I left it over the weekend. Monday I call the tech and he tells me that they moved some wires around under the hood and it started fine . I left it there until Tuesday night (FIVE DAYS WITHOUT IT) and it was fine until last night, every now and then, it starts running like @)(&%, I move some wires and its fine, I think its around the PCM. I zip tie some wires out of the way and spray some electric connection spray on the connectors, but getting home tonight the thing acts up again!! It sounds like your beating the side of the truck with a bat!!! Stupid thing only has 4600 miles and I don't (Can't afford) to be without it while the idiots at the dealership look for the problem. Anybody hear of problems with the doodoomax?

The problem is called "ishouldhaveboughtapowerstroke".
No really, I would consider bringing it to another dealer.

Not sure what year your truck is, but the earlier Duramax motors were notorious for injector and injector harness troubles. When the trucks were first released, several people were left w/out a vehicle for months b/c no spare parts had been produced. I would definitely take it to a different dealer.

Sounds like you definately need to find another dealer and get another opinion. If it turns out to be the harness then ask for a new one. Keep going until you either get it fixed or a new truck. You can call GM and get this resolved, the dealerships look really bad when GM gets the info you just gave us. I have not had any trouble from my '02 but the dealer has been great for the few that had problems.

Sounds like your problems are wiring related and can be difficult to fix. The injector issue has different symptoms. The problem stems from Bosch supplying injectors that were built with too soft a metal in the body. Over time the little bit of trash that gets through the fuel fliter is boosted to the Duramax's 23,000# of fuel pressure inside the injector and it sandblasts the body causing it to leak or fail. Even now Bosch is having trouble supplying enough injectors for all the new diesels as well as the replacements. It's not uncommon for a truck to sit for a month waiting on injectors. The good thing is GM is backing the injectors until 200,000 miles.

Dusty... you following me everywhere, or what?!

It's good that GM is covering the injectors. Actually, Brent Johnson just got his replaced a few weeks ago.

You should go to the diesel place web site and ask these questions.

Yea, I have to check up on you Yankee spies

How long did Brent have to wait for his to be fixed? The last time I was at Lynn Layton they had 3 trucks waiting for them, one had been there for 3 weeks. I guess Brent had the dealer closer to Muscle Shoals replace his though.

 

[ViciousV6]

I think he had to wait 1-2 weeks for arrival. He was driving his truck in the meantime.

And for the record, I recently scored 68% Dixie on a Yankee/Dixie quiz!
