I replace the ignition module on the distributor but the old one tested good as well. The fuel pump relay was replaced. Turning on the key yields voltage to fuel pump relay but no pump sound and no voltage to the ignition module. Any ideas?

The 92 S-10 I had did not have an emergency shut off.Yours may, or may not have, depending on what previous owners may have done to the vehicle.
You need to get a factory service manual (not Haines or Motors or Chilton) to diagnose the problem, Most larger repository libraries have them. The FSM's have complete troubleshooting guides.

Sounds the EGR valve and EVP sen is bad even if you tested it. The EGR valve cntrols idle and if carbon up will make the car stall or idle high and low (rpms going up and down) This was common on all cars during that time. I would say replace the EGR valve and senosr. This should take care of the problem. One more thing have the fuel pressure check on the car.

Your ECU is what acctivates your fuel pump realy. Put the key on the run possition and pull the ecu fuse for a few seconds and reinstall it ans it should accivate your realy for 5 seconds, Good luck.
