Yeah, I popped the top of the PCM and it is half full of epoxy.
The ABS on this car has pulsated since I got it when going over a bump in
the rain or high humidity. Never caused a problem though. I figured the
tires were just loosing a bit of traction on the bounce. Not a failure at
all in my way of thinking.

Try cleaning all four ABS sensors off with WD-40 and a cloth. They can
accumulate a tar-like road grime that can cause hard to diagnose problems.

Doug, et All,
Okay, all it back together.
I have 9 vdc, yes 9 not 8, at pin 1 feeding the CPS and also to the CamPS.
I have 5 vdc at pin 1 of the TPS and pin 3 at the MAP sensor.
I put the Temp Sender in warm water and watched the resistance go down.
Pulled and cleaned the Auto Shutdown Relay. (And thumped it lightly)
Checked the power to the PCM and have 12+vdc.
Grounds from the PCM connectore showed continuity.
Now, I f'd something up. I have no fuel pressure.
Of course, no spark either.
I am cleaning and securing connections as I go. What the heck could I have
done now to lose fuel pressure?
I'm going to go curl up in a fetal position for a few minutes.

You have no spark because you failed to replace your Crank Position
Sensor that cues your computer. You have no fuel pressure because it has
bleed off during your attempts to start, the pump only runs for a couple
of seconds during the initial ignition on, then automatically shuts off
for safety reasons on no startup.
