Pull drivers side hush panel. Find Purple wire that goes to clutch
switch. Look at switch and note the color of wire coming back
up.(Yellow??) Will be able to jumper them right there. I used a 3 in
wire with terminals on the end and unplugged the wires going to switch
and plugged in the jumper wire. Use a 12 ga wire at least as it does
carry a heavy current load which is why the switch fails, it gets hot
and the resistance across the points stops current flow.

my car had a similiar problem, wouldn't start after filling it up
on the road, waited 15 minutes, started right up. It happened again this year on my return from Marc Haibeck's getting some work done.
I called Marc, he explained sometimes the little bead on our keys get worn, or a little dirt builds up, or we push the key into the ignition
to fast, and the computer goes into a loop, 12 minutes later it will start.
I waited, and sure enough, pushed the key in a little slower and she
fired right up. food for thought.

Aurora40,Kmoudy and Zr-1 dude are all correct. The clutch starter switch could be the problem. (why mine is bypassed) and VATs if the security light is flashing. 100% correct

That relay....
....starter enable relay, GM P/N 14100455 or ACDelco P/N 15-8426.
I'd check the other things first though just to narrow it down. The relay isn't that expensive but why buy the wrong part to fix the issue.

This is a common problem for 90-92 Z's. By passing the ecm will eliminate 99% of the issue. Find the big purple wire under the ECM. You may have to dig for it, as it lays inside a fat wire harness found under the ECM. Get a 4 pole relay. Bring a 12 gauge wire from the battery to the relay, find a nice ground near the relay, and cut the purple wire as it will be plugged into two locations on the relay.
Make sure the battery is fully charged. Take a volt meter, and test the voltage on the purple wire while attempting to start. If it's under 10.5 volts, the above info will fix your problem.

You need to remove the black plastic panel above the driverside footwell. (The panel that contains the footwell lamp).
Lay on your back and look up at the bottom edge of the dash cluster area. The two relays towards the driverside door are the AC Clutch Relay and the one next to it towards the steering column is the Starter Enable Relay.
The relay covers are black and about 1 inch square. The relays are mounted in sockets and are the same so you can swap between them.
