No, not the PCM. These checks are done at the ignition control module by the coil.

You need to check for power from the ignition switch to the positive side, the pink wire

Then go to the white/black wire and crank it and see if it flashes.

If it does not, then there is no command to fire the coil from the module.

Did the test light flash on the negative side of the coil?

If it did, then the coil is bad.

Yes, this is the sensor and location. The module looks at this signal before allowing spark.

Possible.

Do you have a scan tool to monitor live data to see if there are signals from the crank and cam sensors?

No, I put a deposit down at the parts store and use their's, last time it did not give me any codes because of the new PCM I guess, but I can use it anytime.
Thanks for helping out Roy.
