Why is my car trying to start without the key in it?
Q: Car cranking without key in ignition This is usually a sign of a faulty starter solenoid. When these wires are connected incorrectly or when there is an electrical short, this can cause voltage from the battery to be delivered to the solenoid inadvertently causing the car to crank without the key in the ignition.
Why does my car try to start when I connect the battery?
It could be the starter solenoid. The starter solenoid in your car is a relay. When you start your car, the battery sends electricity to the starter solenoid. When voltage from the battery is sent to the solenoid, a switch is closed inside the solenoid and a current is sent to the starter.
How do starter solenoids go bad?
It can be caused by instances where the ignition switch is left in the ‘start’ position for long. The soldering in the contacts melts, and they weld together. When that happens, the starter solenoid becomes damaged because you can no longer control its switching function.
What to do if your car tries to crank without the key?
One test to confirm the starter solenoid is the culprit would be to completely remove the starter solenoid, tape all the wires you remove well so they don’t short out, and see if the problem of draining the battery and the engine attempting to crank with the key in “start” goes away.
What to do if your starter is not cranking?
If so the relay is stuck. You might be able to jar it open by rapping on it with a screw drive. Otherwise replace it. If the starter does not try to crank, there is wiring problem from the battery through the ignition switch to the relay.
What does no start no crank no click mean?
If you have a late model GM vehicle and turn the key only to hear nothing, you’ll most likely think you have a dead battery—and you may. But a no start, no crank, no click condition can be far more involved than that. In the old days, power flowed through the ignition switch and down to the starter solenoid. Not anymore.
Why does my starter keep turning even when the key is off?
Trying to start on low voltage,ie low battery, jumper cables, will cause the starter solinoid contacts to weld themselves together thus causing the starter to keep running even with key off or motor running, charge the battery and change the solinoid.
