The PCM does run your alternator. Is the A/C working?

Check to make sure the A/C clutch will kick in. This sounds like a bad crank sensor or a problem with the wiring for it.

With the engine running the center portion of the a/c clutch rotates with the pulley when it is engaged. You should also see fluid going by the sight glass on the dryer. I don't know on the sensor.

If the wiring looks OK, replace the sensor after you check to make sure the gap on the old one is set at 0.50" using a brass feeler (or a matchbook cover folded over).

I assume a 2nd Gen 12 Valver has a Crank Sensor as well.

How does one Troubleshoot it and a Fusible link ??
