I have a 96 ford mustang 3.8 recently came into a problem where car starts starter engages but when I go to turn the key off the car won’t go off after doing research and going to a family mechanic was told it was the plastic tab in the steering column. My question is can I put a kill switch on the car to bypass the problem or should I jus get the problem fixed ?

Definitely fix it. Is it a problem where the key won’t go all the way back or you pull the key and it keeps running?

That might be a bad ignition. I’m pretty sure this one is down on the column. You might have to take the steering column down and do some inspecting.

Yeah, that’s my question too. The cylinder isn’t what I’m talking about.


I did have, one time, my f250 key wouldn’t turn off. A piece of plastic broke in there and fell behind the lock cylinder. I just pulled the cylinder out, cleaned everything and reassembled.

Ok, so the action that moves the ignition switch has worn out or broken. Might be time for a junk yard run.

He said everything else was fine but I’m going up there tomorrow I jus wanted to know if a kill switch could solve my problem for now

If your car won’t shut off, it could be a few things causing the issue. One common culprit is a problem with the ignition switch or the ignition cylinder. Sometimes the key can get stuck or the switch may not be turning off properly. Another possibility is a problem with the fuel system, like a fuel leak or a faulty fuel pump relay. It’s also worth checking the battery and the alternator to make sure they’re functioning correctly. If you’re not comfortable troubleshooting yourself, it might be a good idea to get a mechanic to take a look. They’ll be able to diagnose the problem and get you back on the road in no time.

In the meantime if you need to shut the car off, trip the fuel pump inertia safety switch in the trunk. It's on the driver side, all the way in the back by the tail light. It's just behind the thin carpet liner, has a red circular switch that is normally pushed down to operate. You break the connection by inserting a small flat blade screwdriver beneath the head of the red disc and lifting up gently. There also should be a little slot in the carpet liner itself to do this.
