Primed the system , hit the key and she fired up .
Took her for a 20 mile drive and she ran good/strong with no issues . I parked it in the garage and waited 3 hours to restart . She fired right up on the restart . Yes it's limited data but appears to be fixed  . Tomorrow mornings cold start will really tell if it is fixed but I think I'm good to go . Again thanks to all that provided feedback  |
You fixed it, I guarantee it. Diesels are simple, it’s all about fuel and compression. With no ignition system, even the newest ones run on fuel and compression.
And even better, you created a helpful thread while looking for help yourself, in the best forum tradition. A problem and a solution. Now some other dude somewhere in the world w a Duramax will hit the google button and find this, if he’s lucky. If he’s not lucky, he’ll find 10 other threads on the web w people’s life stories and no concise solution. That’s what always happens to me.
