car continues running with key to Off

Hello,

I have recently been having an issue where my car continues running with the key turned to Off. It as though I have not turned the key (engine runs, etc.). What can cause this issue? Thank you All,

Thank you sdaidoji,

Is there one in particular on the pigtail harness behind the lock cylinder that I should look at?

Re: car continues running with key to Off

Typically it’s caused by a bad ignition switch or fuel pump relay.

How have you been shutting off the car?

It has only happened twice, and I pulled the 7.5 amp fuse for the ECU. Thanks,

Re: car continues running with key to Off

Maybe your ignition switch is shorting intermittently. Cannot say for certain, though.

I have seen a alternator’s voltage regulator do something like this on an a very old model car...but I would suspect the ignition switch first

Hi Chezboat24,

This shows how little I know about the ignition system, I'm sure, but would a faulty ignition switch not keep my car from starting? Thanks again All,

Re: car continues running with key to Off

It depends on why it's faulty. Worn contacts, for example, will stop it from functioning. It sounds like there's a short somewhere which keeps giving the ignition power, which may explain why the car continues to run.

Re: car continues running with key to Off

OK, I think that makes sense to me. Is there a particular wire that I could hook up to a kill switch if I have difficulty sorting out where the short is?

Re: car continues running with key to Off

You can get a new switch for pretty cheap.
Do some testing before throwing parts at it though

Re: car continues running with key to Off

Fair enough guys. I think I get pretty apprehensive about electrical issues. I will take a voltmeter out to the garage, though, and see what I can find out. Thanks.
