The OBD1 engine is notorious for electrical gremlins. Trace back around through your ignition system with a multimeter. Make sure you have the correct resistance through plug wires, coil pack as well as timing.
Just as a quick test, place your test leads on either the left and center, or right and center of the distributor connector. Have someone crank the engine over and verify you’re getting signal from the distributor and mainly the hall sensor.
Couldn’t hurt to check the timing of your intermediate shaft as well. pull the cap of with the engine set AT TDC not 6 degrees before (triangle on the flywheel/flexplate at crank)
hope this helps
