So I'm having no spark. Changed coil pack and spark plug wires as well as crank sensor. I am getting fuel and compression as well as a fully charges battery. Also am getting 12 volts to the coil power wire connecter. But not getting any juice to the other 3 wires on the wire connecter. Don't know where the ignition control module or pcm are on this car or what wires to check. Thanks in advance.

    The only codes that did show up were no rpm signal. Kind of a vague code. But I did change the crank sensor. No change.

    No sir. I looked at wiring diagram and the coil pack has 4 wires one is hot wire other 3 go to ECU.no ignition control unit on this model.both crank and cam sensors seem to be outputting voltage during cranking.
