Fuel pump in Duramax - more detailed description of problem now...
Going to edit this sicne I now have more info on the problem that might help....
so I started my truck a few days ago and was sitting there with it in park, then it stalled for no aparent reason and would not restart.
This happened once before and I changed the fuel filter and it started and ran fine from then on. we just had the injectors changed in December and we figured that was what had caused the earlier problem.
so i changed the fuel filter again hoping it would help, once I changed the fuel filter if I prime it it will run until about half the fuel is out of the filter then stall.
We had it towed to a garage and they checked the injectors and injection pump and all is fine.
There are no warning lights or gages on at all.
if you prime it and start it then hold you fut on the throttle it stays running until you let off.
While holding the throttle open the spedometer bobbles slightly but everything else looks normal.
The garage wont look at it unless I allow them at least 4 hours diagnosis time which is extremely costly. so we are going to bring it hoem and see waht we can rule out first to at least save some time and hopefully find the problem ourselves.
any suggestions on where to look would be helpful.
Thanks
