If there is no voltage, then you will not have spark at the spark plugs.

You lost me already. I'm even new to using a volt meter properly.
The top left circular hole with that white post in it is where you're pointing I presume? To read the voltage, I would put the red pin of my meter on the cable I pull from that hole and the black pin would then go where?
I'll run these tests but since there's never been any indication of a problem with the CPS I'll have to go at this from where I left off; still trying to find out if a car will start if a voltage regulator is burned out. For the CPS to all of a sudden go when all the related problems have been with the FPR, OVP etc seems improbable. I need to get this car running by morning one way or the other.

Also, check the CPS resistance with engine off, (NOT turning over).....it should be between 680 and 1200 ohms.
For record, my CPS pulled off at the ICM reads:
814 ohms and .842 volts ac cold
900 ohms and .986 volts ac hot
Do a search and see what other members have experienced with a bad CPS.
The upper left position is the CPS connection. The other end goes behind the oil filter.

I believe I'll have to buy a manual. I've spent much time searching and still would know exactly what the CPS looks like. Is it indeed the round looking unit with a single wire about two inches back of the oil filter on the top of the bell housing? What I'm talking about can even be accessed with my hand since I studied it a bit and couldn't figure out how to remove the wire let alone the cylindrical looking unit. I've read other threads in the forum - here's what they say in general...
"Removing the sensor from the crankcase has been one of my worst jobs soo far. It was kind of bonded in place."
I won't be doing that job.
