240 sx/se will crank won't start.

Drove car all day went to start it, no start. Push start the car shuts off. Next day start car, car runs put it in gear shuts down. Checked all sensors and fuel pressure and delivery. Swapped out distributor car still has no spark, performed volt test with dist,. gear spinning volts verified at C and D pins at 5.1 volts, when gear is spun no change in volts, like if computer does not sense change. Checked all ECM power and grounds AIT,MAF,TPS etc. all good. WTF is going on, could the eccs relay kill my spark? I have no codes except CMP #11. Is there something I am missing to check?

your going way to technical too fast. have you gone back and checked the basics. sometimes they can be fixed real easy. just remember this phrase K.I.S.S. Keep It Simple Stupid no insult intended
