1980 F350 400 wiring problem

Just bought this truck to use for work. We were told it needed some push rods, but hadn't been touched in a few years. We get it home and start looking into it and the internals have all been repaired already. So we get a fresh battery and clean gas and turn it over....cranks but no start. Long story short, we've replaced the coil, starter, Duraspark ignition module, ignition switch, solenoid, fuel pump, fuel filter and have nice fat spark. I get the feeling that something is wrong in the wiring of the ignition system. Does anyone have an easy to read diagram of what wires go where between the battery, solenoid, coil, and starter? This thing is turning into an electrical nightmare!!! :confused::banghead:


1980 F-350 6.6 400 V-8 automatic and it looked like it had been stripped and put back together by a kindergarten class

Any help is appreciated.

Thanks to all who looked. Found the problem was a bad ground and a bad connection on the coil +.

Glad to hear you found the problem and posted the solution for any future Ford truck owners.
