Getting no power to fire spark plugs. Got the constant twelve volt power going to ICM but not to spark plugs. Cranks over and has fuel. All fuses are good. Just has no to fire spark plugs. Changed ICM and coil pack.

It sounds like it could be the crankshaft position sensor. Do you have a multi-meter to do some testing?

Thanks for getting back with me. I do not have that meter. However, that is not the problem. Could it be the ignition itself?

How do you know the crankshaft position sensor is not the problem? Also, you verified there is not spark while cranking the engine over?

Have you checked to see if your setting any codes in the computer?

Lets check the wiring for the system to confirm and if okay I believe the PCM has gone out. Here is a guide and the engine wiring diagrams to confirm the issue. Check power and grounds for the PCM.

Check out the diagrams (below). Please let us know what happens.
