if it only runs with the OBD2 cable plugged in, look for a missing ground wire. I have heard of this happening before, and the cable is providing the ground to the pcm. Not sure if it is your problem or not, but something to look for.

There should be 0 reason why it would run with the cable plugged in, but now unplugged.
