I have a 71 Bronco with 302 and converted electronic ignition from a 79 Granada. It's been running fine for over a year. Last Thur. it would'nt start, it turns over fine but when you relerse the key from the start position it tries to start. A day later it started right up. Today Tues. the same thing happened, so I got my remote start switch and removed the coil wire from the dist. cap and grounded it on the engine. I turned on the key, then I pressed the remote start switch and had no spark. When I released the remote start switch there was a weak reddish spark. Is this the coil , ignition switch or something else. Please help !
