heres the problem. i turn the key onto the on position. fuel pump will not shut down, primary injector sprays way too powerful causing systen to flood. fuel pump was replaced, fuel regulator was replaced twice. fuel injector was replaced, map sensor replaced, throttle position sensor replaced, and even pump was replaced to make sure there was no pump failure. all new seals and rings put in for throttle body. battery was disconnected and the injectors went to normal. after truck ran for 2 minutes, i pushed on fuel pedal and it started to stumble, pop thru the throttle body. shut it down, disconnected battery and now secondary injector opens up and delivers too much fuel. does this sound like a pcm problem??? any help would be appreciated; i believe this is an electrical problem.
