58 custom cab
 

I'm having a issue with my truck you guys are the gurus so ill ask y'all 1st. Here goes the truck starts and runs fine but when I go to turn it off and pull the key it stays running . Even with the key out what's he deal with that. Any help is greatly greatly appreciated ..

Ignition switch could be bad, someone could have wired the coil wrong so that something is back feeding power to it with the key off. How do you shut the pickup down? That would help diagnose your problem (maybe). If there was constant power to the coil I would assume it would burn out but if you are shutting the truck down by removing power to the coil it wouldn't be. I would get a test light and go to town under the hood. If you don't have one they are $2 from harbor freight. Do a google search for a wiring diagram, I know I have posted them on here before.

Let us know what you figure out!
