Just got the motor rebuilt, got it back in the car. Tried to start it but nothing. No spark, No inj. pulse. Crank sensor is new, I just set the cam sensor. I hooked up an Snap-On scan tool but its not reading the ECM. Any thoughts, can someone tell me where to start? Do you think I have a bad Crank Sensor , or ECM. Any replies would be helpful....
