signs of a bad starter solinoid should be a slight clicking and no-crank
The starter solenoid is attached to and an integral part of the starter.
Probably a bad starter solenoid.
You should locate and test the solenoid. Most have three connections. There is a large cable from the battery to the solenoid, from the solenoid to the starter and from the start switch to the solenoid. The power terminals to the battery and the starter are large and have large cables. The starter switch connection is much smaller. Turning the key to 'start' provides a low current voltage to the solenoid causing the solenoid relay to close and power from the battery cable to connect through to the starter. If that voltage is present then the solenoid or the wiring between the solenoid and battery or solenoid and starter is suspect. If that voltage is missing then the starter switch or solenoid feed line may have failed.
Starter solenoid sticking. Replace the solenoid if it is external. If it is internal, then just replace thee starter. It will cost a little more but you will have a new starter and solenoid.
Good power all the way to the starter, 12 volts at solenoid/start circuit wire when key engaged, but no click or starter engage
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.
The starter relay or solenoid is probably the problem.
Jump the wires on the starter solenoid - Jumper wire connected the large cable running to the starter and the smaller "trigger" wire The solenoid in most vehicles today is located ON the starter. If you attempt the aforementioned answer, BE CAREFUL.
your ignition switch or the starter solenoid is bad try jumping the solenoid instead of the starter, if this does not work, then change solenoid
usually this means that your solenoid needs to be changed
There is an electrical problem between the starter switch and the starter solenoid. The most likely cause is a loose connection at the solenoid or the fusable link has melted.
When opened by the starter switch, it sends electricity from the battery to the starter motor to start the car.
