2 blinks pause 1 blink (3rd code)
4 blinks pause 2 blinks (4th code)
4 blinks pause 4 blinks (5th code)
5 blinks pause 8 blinks (6th code)

It then went through these over and over again... what are these codes?
17 spark reference circuit. Crank sensor, Cam sensor, or ICM are the likely culprits other than wiring.
18 Cam/Crank error. Backing up the code 17. Looking more like a sensor now.
21 Throttle position sensor. Is it installed correctly? It'* thinking it'* at wide open throttle if the voltage is high. You have a sensor or wiring problem.
42 Ignition Control Circuit. Your PCM cannot take over control of the timing and fuel, so the ICM has to run in Module Mode. You may have a bad Ignition Control Module or a faulty connection or shorted wire.
44 Oxygen sensor. It'* either bad, or you have a wiring problem with it.
58 is a known bug in the 92 PCM. Ignore it.
At this point I'd start suspecting a possible bad PCM, however I think the first thing to do is change the ICM. It'* not handing off control to the PCM for timing and fuel. It MAY also be causing the other two codes that point to cam/crank sensors.
If that fixes those codes and the car starts, replace your TPS and O2.
