I was driving the truck down the road and it just died, before that i had just put new thermostats in and was just taken it for a test drive when 100 yards out o f my drive i died. It would not re-fire and wasn't getting fuel to the injectors. I put a new fuel shut of solenoid in and it will start for like a second and shut off. Before i dumb money into it what are some solutions, i put 5 gallons of diesel in to make sure i wasn't out of fuel.

 

Check PCM gnd at back pass side of engine, you have FSD relocated to air box was that a new one or a once IP mounted one relocated to air box, check those pins for corrosion also where did you get your extension harness to make it reach that far.
