SAME PROBLEM.
Reco Holden 186 engine with a clutch.
Engine recently fitted with Yella Terra head and 350 Holley.
Compression probably high but starter spins the engine ok.
I have a starter moter that drops out, as though the engine has fired. Ive disabled the engine from starting and still the starter drops out after perhaps one revolution of the engine.
Ive had the starter out and is working fine. The teeth on the cog show no signs of wear nor are the teeth burred in any way. Anyone would call it a good starter. Took it to a auto elec for a second opionion. Its fine.
We agreed it was a good idea to shave off three milimeters from the end of the starter to alow the cog to enter into the ring gear ferther.
This done and refitted it still drops out before the engine has a chance to fire.
Cover plate removed from clutch and inspected ring gear. A few fine burrs or rather a sharp edge on the ring gear was found. Dident think it would affect the starter but filed off the sharp edge and carefully inspected (and checked with a file) each tooth TWICE!
Starter still throws out before the engine fires. Still drops out after about one revolution of the engine.
Sounds like the starter solenoid is stuck. Another possibility is the ignition key switch is not automatically returning from the start to run position. As the switches get older they seem to get stiff. Could be a weak spring in the switch or just gummed up lubricant. The easy test is to try turning the key counter clockwise after starting the engine and see if the starter motor stops running.
The clicking noise you can hear is the starter solenoid clicking into place. If the starter motor does not turn the engine immediately, it is probably the best place to look. it sounds like the starter motor is faulty.
With the flywheel spinning at about 1,000 RPM at idle, the starter, if engaged with the flywheel, would be forced to spin between 15,000 and 20,000 RPM. Once the engine has turned over and is running, the overrun clutch will release the starter from the flywheel and prevent the gears from re-meshing (as in an accidental turning of the ignition key) while the engine is running
if the motor cranks when you turn the key it is not the starter because in order for the engine to crank the starter must be turning the motor. it could be electrical or fuel related or sensor related, ect. depending on the model and year you could check for fault codes ie:OBD 1 or OBD 2
possibly the starter gear that engages the flywheel is getting hung. One solution is to replace the solenoid if it is exernal, but likely another starter, Make sure the starter bolts are tight, try to wiggle it.
If you mean in context of motor sports then its revolutions. When a car reaches 3000 Revs it means the motor is turning at 3000 revolutions per minute
When the starter motor refuses to turn over or grinds and clicks when turning then you need a new motor or recondition the old one.
More than likely the starter is defective.
The soleonoid on the starter is bad. When you buy a new starter it comes with the solenoid. Try tapping on the starter with a hammer if it starts after that then this is your problem
starters turn but doesnt crank? If the starters are turning and engaging they will at leat be turning the flywheel, unless there is tooth damage. try to rock the vehicle in gear to test. look at bottom pulley (where the belts are) to see if crank is turning, both when starter is turned and when rocked in gear, this will at least tell you that the flywheel is attached to the crankshaft, and if it turns off the starter motor it also shows the starter motor is working correctly. If this is turning via the starter motor the next thing i would check it the timing/cam belt. behind the plastic cover behind all the belts, especially if the engine is turning fast, wirring and not making the usual chug chug chug starter noise!
no if it wont turn over its either the starter motor or the starter relay in the fuse box
If you can hear your starter motor turning but not the engine you have some teeth missing on the ring gear. If you can hear nothing, not even the starter motor solenoid clicking into place, you have a connection problem between ignition switch and starter motor.

starter motor is bad
Yes you can, the power will not be stored though, the LED's will only light when the motor is turning and their brightness will depend on the velocity of the motor's revolutions. Dont forget your resistor.
This usually means a sticking solenoid that keeps the starter engaged after activation. The fix is to remove the starter and clean but my s-10 starter is a closed unit so you will have to replace the complete starter and solenoid unit.
