1976 Ford Bronco IGNITION

In 1976, the stereo had nothing to do with the ignition. Are you getting spark and fuel to the engine? Is the starter working?

Yes...It cranks over like it wants to start, but when the key is released to the "RUN" position, it just dies. My thought was that BEST BUY or CIRCUIT CITY, can't remember who, when they installed the stereo, they might have wired the stereo to the ignition or something. That is the only thing I can think of, but I have not re-installed since then, so I don't really know

There really isn't anything they could have done. At least as far as I can think of. Since the starter is working, are you getting spark and fuel to the engine?

Hello, on older cars they had a ballist resister on them. It would be on the fire wall under the hood in front of driver side. It is white about 1/2 inch by about 4 inches long. I had the same problem on my car. I turned the key and it wanted to start but when i let go of key it died. Good luck.

Wow! it's been awhile since 76, but they did have the resister. Chrysler really had trouble with them in the early 70's. The resister is bypassed when the key is in the start position allowing more power to go to the ignition for cold starts. Once the key is released, then the power went through the resister to cut the power down. It helped prevent premature ignition failure. Now keep in mind, if the engine fires when in the start position then dies in run, this could be a very likely resolution to the problem.

Thanks to reboom for getting some of the cobwebs from my brain.
