My buddy has an 04 that quit running the other day. Said he was driving it and it started acting like you were holding the brakes on it. Stopped and shut it off went to leave and it won't start. Truck will bump off either and run but will not start on its own. Hooked the solus up to it and it's only building about 1000 psi while cranking. If you start it on either it idles fine but as soon as you give it throttle rail pressure drops off. Put a new rail pressure sensor on it that I had laying around and pulled the line off the pressure relief valve and cranked, still does the same thing. Fass is pumping good so it's getting low pressure fuel but it seems like it's just bleeding all the pressure off. Any ideas of what could be wrong with it and what to try next?
