I hate to say it, but on a 1995 that's pretty much the best bet. Without the ODBII capability there isn't much else you can test. I can try to find a wiring diagram so you can test the injector leads at the PCM side if you would like to attempt it. That would rule out a break in the injector wiring and help diagnose the PCM.
Here is the jeep PCM connector. You can see the injector drivers on the pin-out table.
Yeah, something is shorted. Check towards the back of the fuel rail bear the firewall. I have seen wires rub through back there and short out.
1. Check for a short to ground for the ignition coil.2. Check for a short to ground in the fuel injector feeds.3. Check for short to ground to the alternator, or a short in the alternator field.
Oh, good. I was looking everywhere for a different diagram and couldn't find anything. Let me know how it goes.
Any way you can get a hold of a noid light? You can plug a noid light into the injector's connector and see if it will light while cranking.
