Okay, so the car was running great at the track in Hastings, Nebraska last weekend… In the Sunday race, the coil bracket broke allowing the coil to fall down on the exhaust manifold. After the rubber boot caught fire, the positive and negative wires shorted out on the exhaust manifold. Spark was intermittent while I drove back to the paddock, but the car stop running entirely as I pulled into my paddock spot. The damage didn’t appear too bad so I repaired/changed the wires, connectors, changed the coil and mounted it securely. After the repairs, the car fired right off, but then died after I revved the engine and and now it will not refire. I’ve tried multiple coils, DMEs, a different CPS and all electrical connections check out, but I have no spark. I’m at a loss for what to change next. Perhaps I should just change the engine wiring harness? Ideas?
No spark - strange electrical problem - ideas?

I changed the engine wiring harness and the car started right up. I guess a wire(s) shorted out somewhere in the harness and was preventing the coil from firing. With the new harness, it appears to be functioning just fine!

Yeah… If I wasn’t so lazy, I would have fixed my mounting bracket after Anthony mentioned his failure. Thirty minutes of preventive maintenance seemed too hard but sounds really good after missing 1.5 races and three hours of repair work. I guess you live and you learn…

A coil fell off the fire wall this weekend at the NJMP race. They all may fall off eventually unless you get to it before it does.
