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.

Thanks Bill, but no, the CPS is hooked up.
The pump has been coming on at every attempt before. The bleed off has taken
over 45 minutes before. It's gone up to 32psi at key on, then holds through
cranking and after for over 45 minutes.

That's within range.

Here is the pump circuit.

Hard to say. Having the PCM out for an extended time resets lots of
things. (nothing bad) Double check all pins are there and none have
gotten bent. You can follow the schematic to see if the relay is getting
power and if there is power there for the pump.

I know the feeling. Did the exact same thing new years morning.

There comes a time where you might have to bite the bullet and
have your local service department hook up the DRB scantool and
see what they can find. It's not as cheap as DIY, but then again
think of the cost in time you have put into it so far.

Well Doug, thanks. You have been a seriously good mentor in this.
So, if I get it into them, I ask them to check in out with a DRB Scantool?
The dude at Autozone had said some time ago, that the 93 couldn't be hooked
up to computer. You had to go by the ignition on/off/on/off etc. codes.
Those are cleared now of course.
Well, I've sure learned a lot anyway. I'll post what the final outcome is.
