Why is my starter spinning but not engaging?
Generally, GM type starters will not spin at all if the solenoid is bad on them because without the solenoid engaging, it will not power the starter motor, which is why I am leaning toward scenario 1. I did not try to rotate the engine by hand because to me it sounded like the starter was definitely spinning.
Why does my starter turn over with the key?
If it turns over with the key, the switch is either bad or wired incorrectly. Solution #6: Confirm that you purchased a starter designed to work with your engine’s compression ratio. Engines with 11:1 or higher compression generally require a high-torque, gear-reduction starter. Otherwise, the engine will turn over slowly.
What to do if your starter spins but not engages flywheel?
Hit the solenoid “moderately” with a mechanic hammer, one or two dry blows, if next crank try works, then the mechanism is getting seized and needs maintenance. Starter spins but doesn’t engage.
What to do if your car starter is spinning?
If you just hear a whirring sound like the starter motor is spinning without affecting the motor, then the solenoid is either broken, or there’s a wiring issue on the starter itself. Options are: have the starter rebuilt, replace the whole thing, or see if you can track down the wiring issue on the starter.

How does the starter motor work on a car?
It starts the internal combustion of your engine. When the battery powers up after an ignition, electric current goes to the starter motor. In the starter motor, pinions move the engine.
Why does my starter not engage with the flywheel?
You can hear the starter spinning, but it’s not engaging with the flywheel. What could be wrong? The most common causes why your starter won’t engage with the flywheel is low battery voltage, a faulty starter solenoid, faulty starter motor, and wiring problems.
Why is my solenoid starter motor not engaging?
The other possibility (the worst scenario) is some teeth have sheared of the flywheel and so the bendix is engaging nothing. If it’s the solenoid you need a replacement starter motor, missing teeth on the flywheel is best not thought about. Have you tried putting the car in gear and pushing it forward a little?
Why my starter won’t engage?
If the starter does not engage, then remove the starter and see if it engages without the engine. If the starter does engage, then try to crank the engine over by hand and see if it turns. If the engine does not turn, then the bearings may be locked up or there could be an issue inside the engine.
Why is my starter not engaging?
Causes of a starter that is not engaging. Low voltage battery. The first culprit when you are experiencing battery problems is to check your battery voltage. The battery powers the starter and if it is not working, the starter will fail.
Why does a starter motor not engage?
The single biggest thing that can cause a remote starter not to engage is a faulty or missing hood switch. This device gets installed under the hood of your vehicle and prevents the engine from starting when the hood is up.
Why use a solenoid to engage the starter?
When low-current power from the starting battery is applied to the starter solenoid, usually through a key-operated switch, the solenoid closes high-current contacts for the starter motor and it starts to run. Once the engine starts, the key-operated switch is opened and the solenoid opens the contacts to the starter motor. All modern starters rely on the solenoid to engage the starter drive with the ring gear of the flywheel.
Why does the starter spin but not engage the flywheel?
The Bendix gear is mounted on spiral grooves in the starter shaft and held down (when not engaged) by a spring. When the starter motor is engaged it starts to spin the shaft and the gear can’t accellerate that fast so it slides up the grooves until it engages the flywheel. That is inertia.
Why does my starter make a grinding noise?
Start by checking the mounting bolts for any loose wires. The grinding noise you hear with the starter is due to a clash between the flywheel and the ring gear. Next is to dismantle the starter and check inside for the pinion gears. These are often placed at the front of the starter. The pinion gears engage the flywheel in firing up your engine.
What should I do if my starter is not working?
The starter pinion gear engages this wheel to make your car engine crank. Remove the starter motor and set your transmission gear to neutral. Rotate the crankshaft manually using a ratchet. There is a pulley at the front or bottom of your engine block. The pulley should move as you watch how the pion gears are reacting.

What causes a car starter to not engage?
5 Causes of Starter is Not Engaging 1 Low Battery Voltage 2 Faulty starter motor solenoid 3 Starter motor Plunger or Pinion 4 Faulty Wiring to starter 5 Flywheel damages More
Why does my starter gear not pop up?
Centrifugal force is not involved. If the starter motor does not have enough power to accelerate quickly or if the groove to Bendix gear surface is not sufficiently lubricated the gear will not “pop” up.
