Provided the starter drive is not spun, one of the following areas is probably At Fault. A weak battery A poor, or loose connection (at battery, or solenoid / starter). Dirty or rusted starter drive splines. Possibly, but not probable, a faulty starter.
Don't remember exactly on your rig but I'd check these things. Is the starter properly installed? (it's tight and sitting correctly) Are you sure it's the right starter? Bad starter? Bad cylinoid? I don't know why you replaced the starter to begin with but is it possible the teeth on the flywheel are bad? Hope this helps. Hang in there, you'll get it.
Bad Bendix!
At the back end of the engine is a large ring gear connected to the engine crankshaft. If there is a starter (some engines do not have starters) it will be mounted in the engine such that the bendix gear of the starter can engage the ring gear and spin the crankshaft. It's called a bendix because it jumps out to engage the ring gear (while the starter motor is running) and retracts off of the ring gear once the engine is running (starter motor no longer running). It is typically access from under the car. If you must replace it, let the engine cool off first. Otherwise the starter will be just as hot as the engine is.
At this point it's just a matter of diagnostics. You need to find an electrical diagram of the vehicle and go back, point by point, testing where you get starter signal and where you don't. Pay attention to the wiring on the starter. Many starters have a post that's not used on some electronic ignition systems so you should verify that you have connected your solenoid wire to the right post. Try a jumper from the battery wire directly to the solenoid to see if the starter will engage. If the starter tested good it should engage when you jumper to the solenoid. Next, go back one step at a time. If you're not getting starter signal from the neutral switch it might just be misaligned. Next, go back to the keyswitch. If you're not getting starter signal from the keyswitch you might just need to replace it. Break the problem down into smaller pieces, testing each component individually. Good luck and let us know what you find.
The ignition starter has nothing to do with performance. It just starts the engine.
If the starter just spins and does not engage then you have low battery or a stuck 'bendix' on the starter. -Running hot is a separate problem that may happen for any number of easons.
Assuming the starter motor spins but doesn't engage to turn engine over to start you could have a bad starter drive which is part of the starter assembly or possibly damaged/missing teeth on flywheel ring gear. Depending on year and model vehicle, some starters you can replace just the starter drive otherwise you need to replace the whole starter.
tried to remove starter but shaft and gear seem to be stuck in primary case ..... do I need to open up the primary side to remove, starter just spins but does not engage flywheel.
you mean the starter just freely spins and does not turn the engine? replace starter if the engine turns but does not start its either a fuel, spark, or compression problem. read up on how to check that.
If the starter 'just spins' it is usually because of a faulty starter drive; sometimes called the starter bendix.It can also be caused by a starter that is tired and no longer has the power to 'throw' the drive against the flywheel. In any case you will need to replace the starter.Price out a low-mile used one from a salvage yard vs a rebuilt one from an auto parts store. I hope this helps you. Mark
What do you mean when you say it doesn't engage? Is the starter spinning but just doesn't catch to spin the engine? IF that's the case it could be as simple as a loose starter or as bad as a damaged flex plate/flywheel. But it would most likely be the starter.
You have a bad bendix spring or solenoid,either way you will have to remove the starter and replace whole or just the engagement solenoid
You have to replace the starter drive.
Most often it is the starter and not the ignition.
Typically, just about everything except the starter. But then the starter solenoid works off the keyswitch, so the starter won't engage if the fusable like is bad.
if it bolts on the starter assembly you are probably talking about the starter solenoid. basically its what makes the starter engage. if its a sensor that just bolts near the starter it could be anything from a crank position sensor to a knock sensor.
It's probably the little gear called the "bendix". It will be easier to just replace the starter, but you CAN purchase the gear separately if you want. When you remove the starter, check the ring gear on the flywheel. If it's stripped you just got a much more expensive repair.
