I didnt what would this cause. I never SWITCHED pcms, just disconnected my same one. car wouldnt idle before (maf issues). ONly thing changed since this was disconnecting and reconnecting pcm.
basically car ran before, I disconnected pcm, now it wont start, It fires, it will build up some rpms, but no initial fire.

I've disconnected my PCM before (to be safe you should) to run wires behind it without disconnecting the battery....but made sure the ignition was off. If the ignition was on might need a crank relearn? Time to check for any codes.

maf isnt my concern, as i know what i need to do to find that issue (its p0102) no 12v to pink wire at the moment fuse is good, but since i unplugged the pcm and replugged it in, car will not start, turns over, gets fuel etc, just doesnt want to fire up.
