I have a GMC 2500HD Duramax Diesel with 74,000 miles on it. Truck was idleing for 10 minutes warming up. Shut off and restarted 45 min. later. Drove down the street and it died and would not restart. While trying to start, the Battery not Charging warning came on. Towed it home and changed fuel filter. Primed and would start but stall if not continually priming. Dealer replaced injectors 20,000 miles ago. I also changed batteries today. Still won't run unless priming. Also put some diesel 911 in it when problem occured last Tuesday. Any suggestions would be appreciated.
Thank you,
Greg
I see that you had the injectors replaced 20,000 miles ago. I would still check the oil to make sure it is not overfull. The new injectors could be bad. If the oil level is not overfull then get a paper towel and touch the dip stick tip on the paper towel while oil is on the dip stick. If it's only oil it will not spread. If it has diesel in the oil the oil with spread. If this test doesn't show the injectors to be bad then you have three other possibilities. The FICM (fuel injection control module), the fuel pressure regulator, or the injection pump. It's hard to pinpoint what the problem is without running more tests and the only way to run those tests is with the computer the dealership has. Just so you know your injectors are still under warranty until 100,000 miles. Most likely you will have to take it to the dealership to get you truck fixed. I hope this helps you some.
Fuel filter housings on the older trucks get corroded. The seal to the filter has gone bad. Aluminum housings corrode bad.

Thanks for the reply. The oil appears to be OK. It actually was a quart low. I added some since. I thought about the regulator or pump. Unfortunately they are out of warranty. I am going to borrow a scanner before I bring it in to the dealer.
