Sounds like you have covered most of the bases.
I have an '88 and it sounds to me like your injectors aren't firing. You can test injector pulse with a unit called a "NOID LIGHT" They plug into the injector harness and will flash when the injector fires. You can get a full set for different systems at any good parts store for about $16.00. I wouldn't be without them. Injector pulse is controlled by the ECU, so that would be your next check.
