What is a stuck solenoid?

A solenoid is a type of magnetic switch responsible for helping your starter motor turn on the engine. When the solenoid sticks, the ignition struggles to start. When this happens, usually your key will "catch" in when you turn it to start the vehicle.


Why doesn't my 65 fairlane turn the motor with the switch I need to jump start from solenoid. I has new solenoid and switch.?

Did you replace the ignition switch? Not the key tumbler but the actual ignition switch. If so, you have a wiring problem.


1972 Mustang won't start after the starter solenoid has been changed it doesn't click when the ignition is turned what could be wrong with it?

Solenoid could be installed incorrectly. Could be electrical connection on the solenoid. Did you re-connect the battery? Could be a bad starter motor...or a stuck starter motor. Sometimes a light tap or two on the starter motor (not the solenoid) with a hammer will free it up.


Your 1993 mercury grand marquis will not start after you turn the ignition you already changed the starter and it still wont start sometimes?

If you can hear your starter motor turning but not the engine you have some teeth missing on the ring gear. If you can hear nothing, not even the starter motor solenoid clicking into place, you have a connection problem between ignition switch and starter motor.


Why does a 1996 Ford Ranger XLT 4.0L start when you cross the posts on its solenoid but not when you turn the key in the ignition?

the solenoid itself is probably bad, if not that probably the ignition switch I agree 100%, check the solenoid first then the switch.


Car won't start only clicking sound but will start after repeated tries?

looks like the starter motor. the clicking sound appears to be the solenoid on the starter motor. when you turn the ignition, the solenoid click and its supposed to make contact to the motor. if the contacts are dirty, then the car won't start. repeated clicking will eventually make a little contact allowing the motor to turn. try changing the starter motor or servicing it. you can do it urself. remove the motor and pull the solenoid out. clean the brass contacts. they should be under the connections where the wire from ur battery connects. if it seems to be too much work, just get the motor replaced.


Why will a 91 Lincoln Town Car start with a screwdriver touching the solenoid but not with the key manually?

Not to bash on the last answer, but, the starter solenoid probably isn't at fault here. If it will start with the screwdriver then the starter solenoid is functioning. It either does or it doesnt. The answer lies in circuitry back from the solenoid to the ignition switch. You could have a bad ignition switch or neutral/safety switch.AnswerDefective starter solenoid.


What does a car starter motor solenoid do?

When opened by the starter switch, it sends electricity from the battery to the starter motor to start the car.


Why do I hear a clicking noise when turning the key in the ignition then on the 3rd try the car does start?

The clicking noise you can hear is the starter solenoid clicking into place. If the starter motor does not turn the engine immediately, it is probably the best place to look. it sounds like the starter motor is faulty.


When your car was boosted after it would not start the lights would come on but igntion would not turn over why?

Possible bad starter motor or solenoid. Possible locked up motor (did you run it out of oil?) Possible bad ignition switch. Check all the fuses with a test light.


Car won't start with key switch but will if you jumper over solenoid on starter?

Check the neutral safety switch,it is located on the transmission or on the steering column ,under the dash.


Why does your jet ski only start when you jump the ignition selenoid?

The most likely explanation is that the solenoid itself has failed. The next most likely explanation is that the wiring to the ignition solenoid is not making proper contact or there's a bad ground connection. The least likely explanation is that the electronics that control the ignition solenoid (MPEM or whatever it's called on your model) is broken.
