I would check to see if the motor turns over by hand, by turning the crankshaft pulley with a ratchet and socket. The motor may have seized up.

Rebuilt starter on ranger tested good on bench but just spins on TRUCK won't engage flywheel


If your sure bench test was good and bend ex is not sticking, assuming it is your starter I would say your flywheel ring gear is missing or worn teeth. try rotating engine by hand a quarter revaluation and trying starter again.

Why won't my c1500 1990 start?


Okay it says you checked starter motor and it tested good. what test did you perform? A bench test would tell you if solenoid is good or bad. Try this With starter in vehicle and key on, jump positive power to solenoid it should spin and engage flywheel and start vehicle

Is my starter bad? When trying to start I hear a single click. Voltmeter shows a drop from about 12V to 8-9V while turning. Starter motor gets really hot, load wires between battery and starter get so...


check to see if you can turn the engine over by hand it maybe siezed and not turn over.this can cause this type of starter problem and voltage drop.check all grounds from the battery to engine block and body under the hood,if you have a bad ground it can cause a similar type problem.

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.

it could be the battery and if not enough power is going to starter it will not ingage fully engage and cause slight wear on teeth...Now over years teeth will wear on flywheel but should be ok if none are missing....the freely turning on flywheel is incorrect also....it is hard to turn either way...would have battery checked first....hope this helps....

1994 Camry 4 Cylinder-Starter spins fine but does not seem to engage the flywheel. I have a new starter and battery. Im not ready to get into the flywheel. What else can I test to see why its not engaging...


Well, the easiest solution is to pull the starter and bench test it. Likely areas for your issue is the starter drive, and flywheel teeth. You need to inspect the teeth of the flywheel.

one quick test would be to manually turn the engine to another location and fresh teeth on the flywheel, and try starting again. Engines tend to stop at some spots, and that can cause unusual wear on teeth in one small location.

Sometimes rebuilt starter do not get all new parts, but only what is failing, so it is possible to get a malfunctioning starter drive. Starter drive failure usually turns the engine over briefly, then the starter disengauges....

Sometimes when i go to start my truck the starting motor does not catch the fly wheel and the starting motor runs out. when i leave it sit for a day or two it will than start just fine.


Normally I would disconnect battery and pull starter off and take a look at the starter drive, as well as bench test it. If teeth on drive are worn, I'd just replace the starter drive. If they don't appear worn, apply a little white lithium grease to the shaft where drive slides in and out and bench test a few times to work it in so that drive extends out all the way, and retracts as well. Now take a look at the flywheel with a flashlight or similar to be sure teeth haven't worn bad in spots on flywheel as well. You can get someone to rotate engine by hand while you watch flywheel. Any burrs etc found, just run a small triangular file across them to remove burr and reshape slightly to see if that will help. Re-install starter and try it. Sometimes it's smart to get a price quote on just new drive, as well as rebuilt starter, because a complete starter, (rebuilt) may be close to price of drive only, so a rebuilt is usually a smarter choice and no time in labor for replacing drive.

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!
