'79 wont start
My 79 bronco wont start now. The book i have said to check the coil first. with the ignition on, it gets voltage to both sides of the coil. but when i try to start it, there is no voltage coming out of the top of the coil. The wires cap and rotor are all fine. of course that would have nothing to do with the coil anyway, but at least it limits the problem to only the coil. Anybody know what to check next?

But the book says that you're suppose to get voltage on both sides of the coil. I am getting voltage on both sides, so i assume that the coil is good. Would the neutral safety switch might cause no spark if it were not hooked up or if it were bad?

If you are not getting a spark from the coil wire to the cap.....
And you have power at the coil then the coil is the problem, cheap fix for sure.

I also have a 79 Bronco and the first place to look is the control module located by the driver side hood hinge . A lot of parts stores can test these for you. They are not to expensive, maybe around $30.00.

I replaced the module today. Didn't help a thing. I did notice though, that I get power to both sides of the coil only when the condenser is NOT plugged in. If the condenser is plugged in, voltage will not read at the coil. I guess i'll replace the coil tomorrow and see what happens. As for you, Kraker, i would start where i did and take the coil wire (center one) off of the distributor and if you have a test light, ground the clip end on the battery negative terminal and put the probe in the plug and get someone to crank the engine. if the light lights up, then your problem is after the coil unless it is badly out of time. If you dont see it light up, then test to see if you get voltage at the coil. With the ignition ON, see if the test light lights up when you touch either of the two contacts on the top of the coil. They look like raised buttons.

Your trouble might also be a broken wire going to the pick-up coil (not to be confused with the ignition coil), located inside the distributor. You can trace the wires going into the distributor and see if one is frayed or broken.
