1990 Seville left me stranded... grr!

Pardon me, but I have a question about 4.1/4.5/4.9. The cam in the code is the distributor cam? Or does the sensor use the distributor as a way to check cam motion?

According to the SM the cam sensor is "on the distributor shaft"

The sensor is on the distributor shaft and it monitors the cam position since the distributor is geared to the camshaft.

I can't think of an explanation on all of earth as to why the car stalled, threw an 012(no distributor signal), wouldn't start, ignition module fails all tests and is replaced- car starts fine runs fine but throws 041 (no cam sensor signal) intermittantly now

Makes no sense to me none at all

I had the new module tested,

I thought the only possible explanation was the new module ain't passing along the cam singnal -- new module tests fine all connections seem fine

Check the connector to the distributor. Also, make sure that the wire from the distributor to the ignition module is nowhere near a plug wire.
