If you're going to throw parts at it, replace the pickup coil under the distributor cap.

For a '92, you need both the CPS and cam sensor (in dist) to get spark.
Of course the ECM must be working also.
Best way to check either, IMHO, is to open the connector and put two skinny wires in, re-connect and read voltage on the two wires with a multimeter while cranking. The RENIX has three wire sensors, one is hot with ignition on.
It should pulse the voltage, DC 12 volt scale on meter.

Now, find an electrical type person to give you a hand.
