If the SES light works and you ground terminals A&B of the ALDL, the SES light (ign on not running) should flash code 12 three times, then any error codes three times. When all error codes are displayed it will flash code 12 again.
I would check fuel pressure first, should be 13 psi on the TBI engine. IF OK:
Check spark using a spark plug tool where you connect the plug wire to the tool, ground it to the block, crank the engine looking for spark. If OK
Remove the cap and rotate engine in both directions looking for degrees of play in timing gears.
My guess would be if everything is OK the ignition module is fryed.
IF the ECM will not display codes (12) then the ECM could be bad.
You have to isolate one problem at a time, fuel, spark.
If you suspect a FP relay you can run 12V from the cigarette lighter to terminal "G" of the ALDL. This will run the pump all the time, bypassing the relay.
This car is equipped with a backup FP pressure system. Where if the FP relay fails and oil pressure (while cranking) is above 7psi, the oil pump circuit will power the pump.
