Similarly one may ask, what happens when your ignition switch goes bad?

If the ignition switch fails while the engine is operating it may cut off power to the ignition and fuel systems, which will cause the engine to stall. Depending on the exact issue, the vehicle may or may not be able to be restarted a short while later.

Also, how do you reset ignition switch? Insert the ignition key and turn it to the on position and then attempt to start the engine (crank over), the engine wont start. With the key still in the run position wait 10 minutes and the security light should blink and then go out. Turn the key off and wait 5 seconds.

Consequently, how do I know if I have a bad ignition switch?

You can try a test to check the integrity of the ignition switch by turning the ignition key to the 'start' position. As soon as it tries to start, let go of the key. Allow it to snap back to the 'run' position and note warning lights. If they go out as the switch snaps back then the switch is faulty.

Can you jump a car with a bad ignition switch?

Yes and No, if the switch contacts at the start position we're bad and the contacts in the run position were good, you would be able to push start a car with a bad ignition switch.

How do you test an ignition switch?

Put the ignition key into the ignition switch and crank the engine. If the engine cranks, then your ignition switch is obviously working fine. If the engine does not crank, and you hear a "click" when you first turn the key to the "III" position, then your ignition switch is not the problem.
