Dead opti?
I've got a 95 LT1 in a 88 RX-7. Anyways, I decided to take it for a spin today. Fired right up, ran great. Got about 10 blocks into my drive and the car just turns off while coasting down a hill and would not start with letting the clutch out in gear while rolling. Pulled over and discovered somehow the 5 and 7 plug wires had come off the plugs, 5 just hanging there and 7 was still on the plug just unclipped. I figured that was it so I clipped them back on and the car would not start. Definitely getting fuel but no spark. Just cranks and cranks.
When I rebuilt the engine last summer I replace the cap and rotor with MSD units, but the car sees 6400-6500 quite frequently. Could my opti have **** the bed? Is there a good way to test it so I don't have to rip it all apart to find out its good?

Yup, zero spark. I just left it alone for a few days while thinking about it. Went out there and it cranked right up and started. I was confused so I started looking around with it running and the opti harness looked kinda crooked(the connector has been cracked for well over a year). I touched it and the car turned off and I couldn't get it to fire again. I ordered a harness from eficonnection on ebay so I hope that solves the problem.

I finally had some time to look over the car today(sucks its in a storage unit, they don't like me working on it). I definitely had the #5 plug wire touch the header, melted a nice hole in it and the wire was showing. Makes sense that it would blow a fuse. I looked over every fuse I found in the car and they were all fine. I wonder if I'm even looking at the right fuses. I can't believe the car builder would hide the fuses. I suppose I'll have to do some more troubleshooting.

When my opti pooped itself it had similar problems where the car intermittenly shut off and then would just crank/no start, especially when the connector was having an intermittent connection. And another problem when you burn up a wire sometimes the optispark starts grounding the spark internally and causing internal optispark damage. First thing to check is pull a wire and put a spark plug tester on it to see if your getting spark at all now
