1986 Ford bronco 2 with no spark I have replace the distirbutor and all components on it also have replaced the ignition coil . Still no spark . The ignition coil is hot on both pos and neg side with the pos wire hooked up. any suggestion ?
Unplug the coil, put a test light between the plugs connections and crank the engine, you should see a flashing light, if you do then your new coil is bad, if you don't then either the new ignition module or the new pickup coil is bad, you can ohm out the pickup coil but the module would have to be tested on a machine. Of course there is always a wiring fault that needs to be considered in a rig this old.
does the fuel pump come on? I had a similar problem with a ford ranger pickup, and it ended up being the relay to the ecm. I had no spark, and no power to the fuel pump.
