The car was going fine on its last run and I then got it up on stands to update the AC and rebuild the brakes just as a bit of preventative maintenance as everything was fine. Also put in a new distributor cap and rotor as was looking a bit shabby. Went to start it and strong turnover and fuel pressure at the rails but not a single fire so pulled a plug and no spark. Suspected the distributor cap not being right so checked everything again and all ok. Leads in right place. Pulled the coil lead off the cap and put a plug in the lead and touched earth with the key on run but nothing. I know I need to check the coil and dme but I did notice some wiring that had lost insulation, possibly dislodged when I was putting the AC hose in and wondered if this could be the problem, please see pic, I assume these go to some sensors. Also wondering if these can be done with the engine in the car
thanks
