Checked output of coil ? The infamous blue wire behind coolant tank ? Mine was pretty well corroded and the others weren't in that good of shape either..can't think of module it comes from but with coolant tank out you can see all the wires back there .

Rocketman is correct, the ignition system is operated independently from the ecu.

When you turn the ignition switch to the run position, do any dummy lights turn on (check engine, airbag, or battery indicator)?

Have you checked the 15A "Engine" fuse located in the fusebox under the dash? This fuse directly provides switched +12V power to the distributor's IGN module, the ATX module(if it's an automatic),and turns on the main fuel injection relay.  The wire is black/white stripe.

If you have +12v at the distributor's black/white wire when the switch is in the run position, you should see the tach bounce when cranking the engine.

Chrispoe asked about some basic troubleshooting. Have you done any of it? Help us help you - we're not magic wizards here

Poke'n'hope parts replacement is unlikely to fix your problem. Proper troubleshooting will narrow down the list of causes and will reduce wasting parts, money, and your time

I tried to splice the wiring that the rabbits chewed up but still dont do nothing and I've tested the wires so the only other option is to replace the wiring harness

...Thanks Pappy..!!!...my friend just had a stall/no start on his 93(must be that time of year)..it turned out to be the 8 wire green connect located below the radiator reservoir(you need to remove the bottle to get to the connect).. the blue wire had broken off going into the connect plus the connect was nasty with crud..after I repaired the broken blue wire and cleaned up the 8 wire connect she fired right up....

Same exact problem on the first one I bought for $500.
