Have you reset the PCM by disconnecting the battery for 30+ minutes?

The battery has been disconnected for a few days while I had the Alternator removed doing some other things...

So the magnet is there and the sensor is new. Next step would be wiring I guess. This is an odd one.

I have even replaced the wiring harness that connects the ICM, Crank Sensor, and Cam Sensor .... No change.
