Ford F-250 Fuel pressure Problem
Truck was fine one day then all of a sudden it would die down when you gave it gas. In neutral it revs up fine but not when in gear. I replaced the throttle pos., veh. speed, and map sensors. fuel pressure is good as are all vacuum lines. tried disconnecting battery too. had the diagnostic scan done and said system good.

don't know exact fuel pressure but when I relieved the pressure on the fuel line manifold it squirted out hard. was going to cut out the converter but could it go all of a sudden

if the guts broke loose, it would go to the outlet and cause a huge restriction.
get a fuel pressure gauge and verify the pressure on the fuel pump

the trouble all began after I had gotten on it, maybe that blew it out. but I it ran fine a couple of times. that wouldn't happen if it was restricted. no other possibilities?
