Take it off the vehicle. Put it in a vice. Get a battery charger. Attach the positive cable to the large post on the back of the starter solenoid. Attach the black post to a ground point. Take a test lead or screwdriver and make a closed circuit between the large post at the back of the solenoid and the small one. If it functions as it should normally, it might be fine. If not, you know it's faulty. If the starter engages the flywheel briefly, but then spins freely, your solenoid is going bad.
If you battery has plenty of power, either faulty contacts in ignition switch or starter motor, or faulty starter motor.
faulty starter motor
weak or faulty battery, faulty alternator (or slipping alternator belt causing battery not to charge) or faulty starter motor
Possible Faulty wire or even a starter or alternator failure.
Battery condition/charging system, Dirty/loose battery connections, Dirty/loose connections at the starter, Worn out starter solenoid, Worn out brushes in starter motor, Worn out starter drive gear/flywheel assembly, Faulty or out of adjustment neutral safety switch, Faulty starter relay,
Typically this signifies that your starter motor has either jammed, or is faulty. To check that it has not jammed, give it a whack on the end with a small hammer, or fairly large wrench. If that does the trick, then the starter motor was jammed, if not, you need a replacement starter motor.
If your engine will not turn over the causes could be: 1. Battery terminals need to be cleaned and tightened on the posts. 2. Battery is discharged or faulty. 3. Automatic transmission is not in neutral or Park. If it is a manual the clutch start switch is faulty. It is at the clutch pedal. 4. Bad wiring in the starting circuits. 5. Starter motor pinion jammed in the flywheel. With the car in gear rock it back and forth to release pinion. Remove starter and check pinion. 6. Starter solenoid faulty. 7. Starter motor faulty. 8. Ignition switch faulty.
Several possibilities: 1) battery does not have enough voltage to turn the starter; 2) faulty starter motor; bad battery connection.
no if it wont turn over its either the starter motor or the starter relay in the fuse box
Your battery is low. You probably has to replace the battery. Or maybe the starter motor solonoid is faulty
# Battery connections loose or corroded # Battery discharged or faulty # Transmission not completely engaged in park or neutral # Broken,loose or disconnected wiring in the starting circuit # Starter motor pinion jammed # Starter solenoid faulty # Starter motor faulty # Ignition switch faulty or NSS neutral safety switch bad. If it's a manual transmission there is also a safety for the clutch. If it's an automatic, there is a shorting plug. In either case this switch may be bad also.
The starter bendix is not mating with the ring gear on the flywheel. The soleonoid on the starter motor may be faulty or the teeth of the flywheel or the bendix may have stripped. A bench test of the starter motor would be advised.
