Engine still running after the key is out

I recently bought a 1991 Bronco and have had nothing but problems. Most recently whenever I turn off the ignition and pull teh key out the engine is still running. So I replaced the ignition swith, still no luck. Now whenever the battery is connected the radio and power windows/doors work wether the key is in or out. When I try to turn it over I hear a click from under the hood and lose all power. If I jiggle the the positive lead to the battery i get ACC power again. Please Help.

Sounds like you have two problems. One is the battery leads. I would check both. (Especially in Winter. When my '88 had bad leads, the battery would drain in cold weather...not nice!)

The other is the key/lock. If you have the original key, I would have it copied. If that doesn't fix your problem, replace the lock cylinder. (Since the key tumblers are connected to the ig. switch-having a bad key can leave the tumblers in their position after you've removed the key...from my experience.)
