You need to use a fuel pressure gauge and find out EXACTLY what the pressure is. This is critical on that truck.

i dont have anything to check the pressure with if i had money to buy one i would just take it in to a pro on a guess does it sound like a fuel problem its just wierd cause if i unplug the map sensor its gets power back but rough. cad converter rattles but if i take off the o2 sensor allowing air to come out of the hole has no effect
