2003 GMC Duramax Diesel won't start

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

    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.

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.

    Put an inline fuel pump in it and it will run. Needs only a few pounds of pressure .Mine has 5 pounds of pressure and it hasn't given me any grief since.

i have a 2003 , 2500HD Duramax with 223000km . I was way up in the north country when this started to happen to my truck. I found an old mech. who had to come back into the bush to give a boost because i couldn't start my truck as well. He told me he has seen this before on the 03's. Long story short it was the injectors the dealer replaced all 8 under warrenty. GM sent me a letter later saying they will cover all diesel parts under warrenty for 320,000km and another 6yrs. its your injectors change your oil more often until you get it fixed. To check this park your truck for the day and try starting it if it will not start. Go under the hood and prime the fuel filter (pump until it gets hard) then turn the truck over a little and prime the filter again until hard then start the truck. if this works then get the injectors replaced by GM. This worked for my truck hope it helps. Rick

Truck fails to start


The 01 DuraMax trucks do not have a block heater, unless they were special ordered with one. Just turn the key to the on position a few times before you try to crank it, and hold the accelerator partially down while doing it. However, don't hold the accelerator if it starts to crank, it DOES need a minute to warm up before being revved. Also, use a diesel treatment when its cold, it helps a lot.

4X4 inop on 2003 GMC Sierra 2500HD


I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.
