I just got everything put back together last night on my new engine and went to start it and it starts and runs for a few seconds and dies almost like ignition was switched off. I did not change anything from the last time it was run but that was 2 years ago! Info on what Ive checked: moving the throttle dosnt effect anything tried another IAC I have, no change Fuel pressure at rail is 38-40psi I have a spark tester showing spark, until it dies tried disconnecting MAF to put it fail safe/default along with others sensors one at a time, no change tried adjusting timing, no change spout in or out, no change no visual vacuum leaks removed msd 6al2, no change Could the TFI module of PIP sensor cause this? I thought there were usually issues with them when they got hot. Going to do some checks on the TFI module and PIP tomorrow. I have racked my brain going over things and trying to figure what is causing this. Any help would be greatly appreciated.
