1991 Ford Bronco: 5.8 liter..tried starting..engine cranks over fine.

This answer was rated:

I have a 1991 Ford Bronco, 5.8 liter, that will not start. I drive it daily, then the last time I tried starting it, it would not. The engine cranks over fine. I checked for spark from the ignition coil to the distributor and get none. I am getting power to the coil with the ignition switch on. I took the ignition module to O'Riley auto and had it checked and it turned out to be good. What else could be the problem?

rpmdiag :

Thanks for your question. Sorry you're having car problems, I will do my best to research this and supply you with an accurate answer ASAP. The stator inside the distributor is most likely bad and needs to be replaced. the distributor needs to come out to do this too. Hope this helps you. Thanks, Ron

rpmdiag :

Also be sure that you do have battery voltage to the positive side of the ignition coil from the ignition switch. Ron


Is that wht the ignition module plugs into?

rpmdiag :

Yes it is, and they fail all the time too

I replaced the stator and the Bronco started and ran fine. That evening, after driving it a bit, it wouldn't start again. The next morning it started right up. This afternoon it started fine and after warming up, it won't start again. I checked for spark and it has none. there is what appears to be a condensor mounted on the side of the coil. Could this be bad or the coil? And if so, how do I check them?

He must be away. No answer for 15 minutes.

I didn't know how to test the coil, so I bought a new one and still there is no spark. I'm taking the ignition module to Kragen to have it tested. Other than that I don't know what to do.

The ignition module tested bad this time. I guess the new pick up coil was too much for it and it failed after the rejuvinated spark.
You probably need to put both in again, and Ford parts. I don't trust the aftermarket parts. Ron
