If I understand your statement correctly, noise but the engine will not "turn over." This sounds like the starter motor is running but the gear that engages the flywheel gear-teeth is not making contact at all or is moving into too-slight contact, just enough to make a lot of noise. In U.S. cars the device on the stater motor that moves the starter gear forward is called a "Bendix." As the starter motor starts to turn, the Bendix shoves a small gear forward, engaging teeth on the flywheel which spins the flywheel to start the engine. If the Bendix is sticking or has failed the gear will not move forward at all or not far enough.
Sarting with the least cost first, I'd look toward a "sticky" bendix. Try using a light penetrating oil or perhaps, WD-40 to free-up the Bendix.
The starter has a Bendix that pops in when you start to spin the starter--it or the contacts that engage it could be bad. Had this issue with a few vehicles---starts fine and next time click or will grind and the Bendix is not engaged.
The starter if removed can be examined and or tested---My last one on a 4 runner with it out was able to see burnt contacts and decided not to replace just them but got a rebuilt starter and problem was cured.
May be a good idea for a mechanic to look into this.
Hello sal... On the X type Jag everything comes out fron the top.
and battery box Pull back rubber cover at end of starter
solenoid and undo wires Un bolt 2 bolts that attach the
starter to the bell housing/ Transmission. - these are vertical bolts, you can
see them looking straight down from above. One of them has a ground wire on it.
Then lift starter and wiggle its way out
If you have a manual
transmission, have the starter tested, i have seen the bendix/pinion gear all gummed up with
clutch dust, and then it wont engage properly and will make horrible grinding
noises. This can be easily taken apart, cleaned, relubricated and put back into
If the starter wont turn...Id check / replace starter solonoid.
If the starter turns but doesn't engage the flywheel...I'd check / replace the bendix.
If starter checks good and bendix is good...I'd look at the teeth on the flywheel.
take your starter out and rotate your flywheel that connect to your starter full turn look for any damaged teeth on that flywheel if you notice any your flywheel need replacement if not your starter gear also could be a problem or starter itself is no good .
It sound like the lobes on the starter's shaft have worn down and aren't making positive contact with the flywheel anymore. A "whirring sound" would be the starter motor spinning but not "catching". If it's a clicky/buzzing sound then it would more likely be the starter solenoid, low battery/bad alternator.
The "whirring" sound should still be winding down for just a second after you turn the key off. The "buzzing" symptom will stop instantly when you turn the key off.
I am working on my mother-in-law's 2002 4Runner right now. The problem is a common one for Toyota starters and is likely due to worn contacts in the starter itself. When you engage the starter by turning the key, the worn contacts are preventing enough current from getting to the starter bendix (this is the rod that engages the flywheel and makes the engine turn over. you can hear the starter spinning, but the gear on the starter bendix is not engaged with the flywheel. If you can remove the starter, it is likely you can buy new contacts from Toyota, or your local parts store. Or you can buy a new/refurbished starter from your parts store for less than $200 and you will get money back for giving them your old starter. The tricky part is getting the starter out, which is what I am working on right now.
It sounds like a sticky bendix on te starter. Take the starter off and clean the bendix with electical spary work the bendix back and forth while spaying with the cleaner. Make sure there is tention in the bendix when you push it ahead it should want to go back.
