No fuses blown in the power distribution under the hood?

[haulin99spd]

Can you scan the truck? I wonder if the pcm is working?

[haulin99spd]

i did have a scanner but when i plugged it in it wouldnt connect with my old pcm..the guys at the parts house said that it wouldnt read diesel codes..but i have put a diffrent pcm in the truck and notthing changed..

Hmm strange you have power to the trigger wires for the gpr so that tells me the pcm is working. Look for the fuse in the engine compartment for the fuel heater element. Do you have your user manual handy?

[haulin99spd]

yes checked the fuel heater and is in correct operation, the motor and everything with it is new, it aint got 1500 miles on it since it was put in the truck

[haulin99spd]
