My car has been missfiring occasionally and after getting home and into a parking place the car died won't start at all. There is no spark from the coil wire. It's not the wire, because I checked it with a known working wire and still no spark. It did this last week and after some wire wiggling and poking around it started. I suspect something in the section of wiring harness coming from the ignition box, because that is the only section that has not been repaired, but it appears to still be good.
Any opinions or ideas on how to track down the culprit would be greatly apprecitated.
