If you can hear the starter spin up freely when you turn the key, there are two reasons a starter will not engage properly.

1) The starter bendix needs to be replaced; or
2) The flywheel has some chipped teeth and will need to be replaced.

The starter bendix has a small gear or cog that 'shoots out' from inside the starter and turns the flywheel when the key is turned.

You can try a trick to see if it's the starter bendix - but you must use caution not to damage the starter.

While someone else turns the key (on and off repeatedly) , begin tapping on the starter with a hammer. (Tap, Tap Tap). If the starter engages it's usually a 'stuck' bendix. If you hear any kind of grinding sound this usually means the bendix gear is turning against chipped teeth on the flywheel or in some cases, the starter may need to be shimmed so the bendix engages the flywheel at the correct angle.

You can also remove the starter and take it to an auto parts store that has a starter tester (like Auto Zone). They'll be able to tell you if it is a defective bendix. Also, when you remove the starter you may be able to examine the flywheel for damaged teeth if there is no shield around the flywheel.

Starter clicks but will not turn engine over on 2004 Dodge Durango. New starter and battery.


Hi Mark
Sounds like you are doing all the right things.
We used to Load Test a Starter Motor by putting it in a Large Vice and connecting a known good battery with solid fat jumper leads.
When the solenoid throws the cog forward to engage we would use a 2 by 4 block of wood levered against the cog to try and stop the starter from spinning. The wood burns up under load but it quickly proves the Starter is functioning under load. Without using the engine.
Also you could try removing the spark plugs on the engine to allow the compression to escape. Make sure NO sparks around to ignite any fuel vapor.
The engine should spin over easily like this and you can hear & see if anything is binding up.
Hope this Helps!
Good luck!

1999 Pontiac Sunfire 5 speed won't start. Replaced spark plugs and checked ignition coil (fine). Sounds like it wants to turn over but makes a "whining" noise. Please assist. Thank you!


Is the engine turning over with the key in the start position? If the engine is not spinning over and you hear a whining noise, the starter is not engaging the flywheel. If the engine is turning over with the starter engaged, the engine has most likely jumped time that creates low or no compression which results in the whining noise.

Turn key get nothing jump starter and sylenoid just spins


i cant dope out that symptoms.

does it crank or not. be clear there.

no car starts (but my 6sp) if it dont crank.

on A/T cars cranking is a first thing. so does it.?

Solenoids do not spin, the stroke only , it a linear motion.

the Sol. moves the pinion and the main contactor switch only.



my guess is the Starter spins and the crank don\'t spin,

you hear the starter motor spin up, it sings. like bird.

that means the starter /solenoid are bad. (crude)

if the battery is good and or jumper starting off a running car.



It can just be a dirty starter pinion, clean it , repeat.

fixed many for this. i have.



battery cable lugs clean, and good. no green rust.

bad cable usually just make a loud THUNK sound. no spin.

Why is my starter not turning my engine?


Sounds like the bendix is stuck. When the starter motor spins, the inertia makes the gear that engages with the flywheel fly forward and engage. When you release the key the gear returns back to its at rest position. To fix it, remove the starter motor, flood the helical grooves with WD40 to clean it, then apply light machine oil like 3 in 1 and then wipe off an excess oil.

Loud noise when ignition key is turned on, but engine will not engage. j


If it sounds like a motor spinning the starter is not engaging. Solenoid is bad in the starter.

When I try to start, why does it sound like the starter is spinning and not engaging anything?


You may need to take the starter off and have it bench tested.
The problem could be the starter drive, or you could have some missing teeth on the flywheel. The drive is supposed to extend when the starter spins to make contact with the teeth on the flywheel. You could also try turning the crank a few inches and try the starter again.

Battery is good but when I turn it on it just clicks won't start,maybe after 20 times it starts


Without hearing the sound it makes - it's kind of hard to diagnose.

The engine starting process consists of turning the key to start, the starter motor's rotor moving forward to engage the engine's flywheel, and then the starter motor 's "rotor" spinning until you move the key from "start" to "run". You can hear the starter motor spinning - but one usually can't hear the rotor moving forward to engage the flywheel. As a result, you hear the odd spinning sound - which is the starter rotor spinning. The engine never actually turns over because the rotor never engages the fly wheel. If this is the case, then it is very likely that your starter needs to be checked and / or replaced.

Good luck!

When I turn the key the car jus makes noise and doesn't turn over. Would that be the starter


If you mean it sounds like an electric motor just spins, it is your starter-the bendix gear is not kicking out and engaging the flexplate to turn the engine over. If it is just a clicking sound, it is probably a weak or dying battery.

Cranks fine, won't "catch"


From what u describe, I believe u have a starter and possibly a flywheel problem. When u turn the key to start the car, the starter gear engages w/ the flywheel, turning the flywheel, which turns the engine over. It sounds like the teeth of the flywheel and starter are worn, (they should mesh together smoothly) which would make the grinding noise u describe. If this is the case, the flywheel and starter would need to be replaced, and its a labor intensive job, as engine and trans. have to be separated to remove/install the flywheel. The rrrrrrr sound could be the starter gear spinning but not engaging. The starter gear extends on a shaft, then engages the flywheel. It is possible the gear isn't moving forward on the shaft, just spinning w/out engaging, making the rrr sound. So, I would recommend u remove the starter and have it tested (many parts stores will do this for free) and check the teeth on the gear to see if they are worn or broken. U will also be able to see a portion of the flywheel after the starter is removed, and u should check the teeth on it also. Let me know what u find, hopefully it's just a starter problem, and the flywheel is ok.

Starter makes weird noise dosent turn over


Starter drive not engaging fully . Sticky or worn, but don't think changing thermostat had anything to do with it. Try having starter drive inspected & lubed if possible , but you may end up with new starter.
