You have one of two problems: Either the starter drive on your starter is defective and is not engaging the flywheel to crank the engine, or the flywheel has some broken or damaged teeth that are preventing the starter from engaging.
Starters come in a variety of designs. On some, the solenoid is mounted on top of the starter. When you turn the key, the solenoid routes current to the starter motor and at the same time pulls a lever that slides the drive gear mechanism out so it will engage the flywheel and crank the engine. If the solenoid is weak or damaged, it may not be strong enough to overcome the spring tension that retracts the drive gear. So the starter spins but doesn't crank the engine.
On other starters, the solenoid is mounted remotely. When the starter motor starts to spin, it ratchets out so the drive gear will engage the flywheel and crank the engine. If the drive mechanism is damaged or hung up, the motor may spin but not crank the engine.
Regardless of what type of starter you have, it will have to come out for further inspection. The drive gear (which is sometimes referred to as a "Bendix drive") should move out when the starter starts to spin. The drive gear usually has a one-way clutch that is supposed to protect the starter against damage if someone keeps cranking the engine once it starts. The gear should turn one way but not the other. If the gear is locked up or turns freely either way, the drive is bad and needs to be replaced. If the drive can't be replaced separately, you'll have to replace the entire starter.
Starter Testing If the drive seems okay, the starter should be "bench tested" using jumper cables or special equipment designed for this purpose.
CAUTION: Be careful because a starter develops a lot of torque. It should be held down with a strap or clamped in a vice (be careful not to crush or deform the housing!) before voltage is applied.
A simple no-load bench test can be performed with a battery and a pair of jumper cables to see if a starter motor will spin. But this test alone won't tell you if the starter is good or bad because a weak starter that lacks sufficient power to crank an engine at the proper speed (usually a minimum of 250 to 500 rpm) may still spin up to several thousand rpm when voltage is applied with no load.
A better method of determining a starter's condition is to have it tested on equipment that measures the starter's "amp draw." A good starter should normally draw a current of 60 to 150 amps, depending on the size or power rating of the starter. Some "high torque" GM starters may draw up to 250 amps, so refer to the OEM specifications to make sure the amp draw is within the acceptable range.
If the starter does not spin freely, or draws an unusually high or low number of amps, it is defective and replacement is required.
An unusually high current draw and low free turning speed typically indicate a shorted armature, grounded armature or field coils, or excessive friction within the starter itself (dirty, worn or binding bearings or bushings, a bent armature shaft or contact between the armature and field coils). The magnets in permanent magnet starters can sometimes break or separate from the housing and drag against the armature.
A starter that does not turn and draws a high current may have a ground in the terminal or field coils, or a frozen armature.
Failure to spin and zero current draw indicates an open field circuit, open armature coils, defective brushes or a defective solenoid.
Low free turning speed combined with a low current draw indicates high internal resistance (bad connections, bad brushes, open field coils or armature windings).

SOURCE: battery is good. clicking sound when trying to start engine

Better solution;
This sounds like it might be a corroded fusible link. Not enough current is getting to the starter.
I assumed you cleaned the battery cable connectors.
Test to see if the headlights will shine bright. (They are on the other battery cable)
The fusible link is generally located in one of the two cables coming off the positive battery terminal. It's a fusible bar that melts at over current. Sometimes the contacts on each end will corrode and need to be cleaned. Trace the cable until you find it. It might actually be in a fuse link box. If so unplug and replug all and see what happens.

If you throw booser cables on does the car start ? If it doesnt then its time to replace your starter and relay.

SOURCE: starter will not mesh with flywheel

Sounds like drive is sticking again. Sometimes if you can remove an inspection cover & spray drive area with white lithium grease it will help, but not 100% if that's possible on your particular vehicle. Did you happen to double check alignment of starter? Sometimes too many shims, or maybe one added in right place will stop binding against flywheel to allow for better engagement.

SOURCE: starter runs but won't engage flywheel

Hello, I would make sure that your car is not one of those half year cars becuase two differn't starters may be offered for the same year of car. Also, I would check and see if your battery has enough CCA's to power your system. The only other thing is to turn your crankshaft with a breaker bar to turn your flywheel to possibly get a fresh area of teeth on it. If none of this fails it's as simple as just replacing the flywheel. If you did a bench test on the starter and the bendix engaged that is good. Buying parts from an Auto parts store does not gurantee the part is good and that the bendix engages the full distance to turn the flywheel. I would try to find a mechanic who rebuilds starters to make sure that the bendix is engaging fully. I hope this helps you!

If the starter bendix is working then they gave you the wrong starter. or if yours has the cylinoid mounted on it , this woud be bad. either way you will need to take it back to the store. flywheels can't be adjusted

Just to be sure. The starter gear moves up the shaft and spins. The flywheel is also spinning. So it is fast and because both gears are turning I am assuming they are engaging. Is this correct?


The starter gear engages the flywheel, yes. The flywheel is connected to crankshaft, so the engine--flywheel- starter drive gear spins. When you release key to run position, the starter disengages and hopefully the engine is running.

I have a 2005 brute force 750 and put a starter on it and when I hit the start button it just spins the starter and it doesn't sound like the flywheel is spinning. What can I do to find my problem


When you first turn the key to"on" most starter posts pop out to engage into the flywheel gears. If you don't hear a click when turning the key to "on" re-check the wiring.

Starter wont engage


either the starter is not kicking out its gear to meet the flywheel or the flywheel has missing teeth. either way the next step is to remove the starter so it can be tested outside of the vehicle and the flywheel can be looked at through the hole where the starter sat.

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 turning key starter turns over but not engaging


if starter just spins and does not engage flywheel. it is usually the starter solinoid not kicking it out. when energized the solinoid, if good. kicks the starter gear into flywheel to turn engine over to start it. good-day !

2000 chevy impala, starter spins but does not engage


if the starter spins but does not engage flywheel. then its the starter solinoid thats bad. its on top of starter, when key is turned to start, the solinoid is activated, and it pushes the gears out to make contact with flywheel to start vehicle. so the solinoid just spins with out kicking out to flywheel. change solinoid or get another starter. have a good day !

My 00 impala 3.4 doesnt start.i took the starter off and checked it out but its fine. when the key turns the starter spins but wont engage with the motor.i have a brand new battery,all cables are connected...


Does the starter kick out and spin normally out of the car? Have you checked the condition of the flywheel? Ususally the starter doesnt turn until the solenoid kicks the gear out to engage the flywheel. Check if the gear on the starter is bad, it should slip one way, and not the other.

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.
