It is hard to say what is causing it. The ignition switch on mose cars in down on the steering column. It may be simply the heat of the engine traveling up the steering column. If anything electrical is causing it, a fuse or fuseable link will blow. Ford/Lincoln/Mercury had a recall on ignition heating problems in the late 80's/ early 90's. Actually the fuse would not necessisarily blow as long as what ever the key was short circuiting had some sort of resistance. The fuse would deffinetly blow if it was a direct short to ground. Of course this is assuming someone in the past hasn't circumvented some fuse instead of fixing the actual problem. It's been known to happen.
Could be a coil or ICM, Ignition Control Module.
Is it an "after-market" radio? It sounds like it was wired to a "hot" terminal that is not controlled by the ignition switch.
Check to see if you are getting fuel.
The old "hot wire" routine only works on ignition systems that use points. I suggest that your efforts may have caused more serious problems with a solid-state ignition system.
check the ignition coil probably becomes open circuit when hot
Slamming on them.
What would cause the engine not to restart when hot Chevy Trailblazer 2007?
Probably not a good idea cause it could be hot.
The ignition of my 2002 Corolla also gets hot? Any others?
Frankly, she isn't hot.
You pulled your muscles that hold up your body in the lumbar region. Rest them and a hot tub bath or shower will help.
I would check the ignition system. Warmed engine stalls can be caused by a failing ignition coil or coil pack. Pull a plug wire, crank over the engine, and evaluate the color of the spark with engine cold and engine hot. Snappy blue at cold and weak yellow (or none) at hot and it's time for a fresh coil.
