Truck won' start

[acedenver]

Help. I have an 02 Duramax stock 198k. Truck will not start it turns over but will not fire. I have changed the fuel filter and the water sensing unit. I am wondering if the fuel pump is bad? How many pumps are on this truck? How do you check the fuel presure?

Did you reprime the fuel filter?

Good call...Our '02 did that when the "Anti-Theft Module" failed...I don't know enough about it, but that's what the dealer called it...Ben???...Can you hear me

make absolutely sure its primed and there are no air bubbles in the system.

has it been harder to start lately like turning over longer before it starts could be injectors
