Have you changed the coil/coils?




Have you tested power to the PCM?


Anti-theft system maybe active, your owners manual will tell you how to deactivate.

Test Light at the igintion power wire to the PCM,when you cut key on sends power to PCM,then if there is power you may need to have the PCM that is original to the motor you replaced,or have the one you have flashed to it,not all PCM will work unless programmed to your car.


Due to anti theft asTennisshoe said.
