Why no fire from the coil?!?!

Asked by May 06, 2014 at 12:27 PM about the 1991 Ford Ranger XLT Extended Cab 4WD SB

Question type: Maintenance & Repair

I replaced the head gaskets on a 91' Ranger 2.9 liter v6. I made sure to mark the distributor so it went back in the same way it came out. After I get it all back together, it wont start. I made sure all pigtails are connected etc. I found that I am getting power to the coil but no spark from it. I replaced the coil and the same outcome. Any ideas? I'd rather not just throw parts at it. ( Ignition control module, etc.)

You should have replaced the distributor stator and ignition module while you had the distributor out. Try this: disconnect the spout connector then try to start it, if it starts you have a bad ECM, if not then disconnect the ignition coil connector and put a test light in it's place and crank the engine, watch for a flashing light on the test light, if the light flashes then your coil is bad if no flashing light then the ignition module and or distributor is bad, replace bad components, start engine, set base timing, turn off engine, reconnect spout connector and restart engine.

There is a little connector that is about 6 inches from the module connector, it is usually taped to the harness, most of them are black but there are a few that are gray depends on where they are manufactured.

Check your ignition switch, make sure it still is sending a steady power supply to the ignition side. If not replace the ignition switch. If it is then check for steady ignition pulse from the ignition module assembly, if you don't get a constant flash, flash, flash, flash then you could have a failure in one of the new ignition components, chances are really high that the distributor pickup isn't any good. Was the distributor you put in new or a reman?
