Question about GMC Sierra 2500HD
It sounds like you have 1 of a few problems happening.
1. The fuel you have in the vehicles is contaminated.
2. You have a fuel pressure problem which is related to the injector pump.
3. Your fuel fuel delivery system sensors are faulty.
If you can give me the model of the engines etc I can give you the process to access the DLC and fault codes also.
But just check the previous 2 first.
You will have to get the injector pump pressure tested at a Diesel Workshop.

I suggest check your MAF. Also checked some of the wiring, fuses and relays and injectors. If you can unplug the top big
harness plug on the drivers side, whats up? And, if unplug the
bottom one it kills the truck? With this, you are check the harness.
Tell us news.
