Can a bad ignition switch cause a bad starter?

The first thing to check in these situations is the battery. If the battery is OK, then you have either a bad starter or a bad ignition switch. With a little bit of time and some patience, you can tell which one is the problem. What Else Is Working?

Why is my key stuck in the ignition?

If the key is stuck in the start position, this is a ignition lock cylinder issue and the reason the starter continues to turn the motor over. If the starter is turning but the motor is not, then the starter is likely the problem.

What causes a car starter to not turn over?

However, when powered, it should send a signal to the starter relay once the key is turned or the starter button is pressed. If you press this button or if you turn the key on a manual ignition switch and the vehicle does not turn over, it may be caused by a problem with the starter relay.

Why does my starter make a clicking sound when I turn the key?
