so now my truck is shutting off. it will randomly shut off now in drive. it shuts off every time i shift into reverse. i changed the egr, fuel pressure regulator, and fuel filter. and i checked the fuel pressure today and it was about 33-35 psi
so what else could be my problem. could the fuel pump cause all this?
Could be a lot of things, are you still getting any codes. What year truck is it...in general I would suggest a full tuneup, and to check the IAC, does not sound like a fuel pump problem, could be as simple as an air filter, or PCV, dirty IAC, or a vacuum line...here is a link Ford Fuel Injection » Idle Air Bypass (IAB)

Have you tried the ignition switch.
When mine went bad, my truck would shut off every time i turned the wheel to the right (even when returning the wheel from a left hand turn) And when ever i tried to change gears (Park to reverse, reverse to drive, ect)
