Answer #1
have you verified spark and injector pulse? what does the tenp sensor read? is it correct.i have ran into a few of these that loose ground to the crank sensor on the yellow or green wire.do you have access to wiring diagrams? if so check for ground at the appropriate wire,if none found.try jumpering it and see if that makes a difference.
