Okay. I thought by '94 all the relays were in the fuse box under the hood. If yours are still on the inner fender, the starter relay will have a fat red wire and a fat brown wire to jump, and a double thin yellow wire. I think the fourth thin wire is black, but I can't remember for sure. If you're jumping the wrong relay, you might be hearing the radiator fan.
Grab a test light with the ground clip on the battery negative post, and go to the smaller terminal on the starter solenoid. Have a helper turn the ignition switch to "crank". You should see 12 volts there when the starter relay clicks. If you don't, jump the red and brown wires in that relay socket. If that makes the starter engage, that relay has a rusted contact. If the relay isn't clicking, jump those two wires again and the starter should engage. The relay contact still could be full of rust, or we'll have to check the neutral safety switch.
If you do find 12 volts at the smaller terminal on the solenoid, move the test light's ground clip to the engine and try again. If you don't have voltage now, the negative battery cable is bad or disconnected.
