Pull the stater and check the teeth on the geat and also check the flywheel teeth, it sounds like the starts is not engaging the teeth of the flywheel.

SOURCE: High pitch noise when turn key to start / engine not turning over

Check your battery first. Cold weather does horrible things to car batteries... if it's more of a grinding sound I would say that your starter gear is bad. I believe they call it a ring gear? I had a similar problem with a kushman scooter that I use to deliver snowcones through the neighborhoods. It has teeth that need to engage and if those teeth have been grinded down it will have a hard time engaging....

SOURCE: Radio lights dim and go out when I hear a squealing sound

Hello Frankmaggart,
Thank you for choosing FixYa.com my name is David.
It sounds like the serpentine belt slipping possibly from either a weak belt tensioner or
your alternator may be trying to lock up look at your belt to make sure it is good and tight
and there isnt no signs of wear or cracking if all that looks good my suggestion is have your
alternator checked out at your local part store.

SOURCE: At high speeds, I here a high pitched squeal

I'd check the passenger side mirror first, make sure it is tight to the window frame, no gaps. It causes a wind noise or whistle. It could be from the outside of the truck, try to pin point. Does noise go away with either window down? Does noise get louder turning in one direction (wheel bearing)? Does it get worse then seem better (could be tire noise)? Eliminate fan motor, and radio. Does it get worse with vehicle speed or just engine speed?

Clutch noise


Bearing noises in a clutch system are easily distinguished by running a few simple tests. Start the engine and leave the transmission in neutral. If a transmission makes noise when it is in neutral it is often a worn input shaft bearing. Now depress the pedal until the clutch just engages. This is the point where the release bearing is just contacting the pressure plate fingers. If you begin to hear a squealing sound this is likely a worn release bearing. If a whirling noise is present when the clutch pedal is fully depressed it is probably the pilot bearing.

Not starting


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.

Hi Eabyrd05.
It's possible that you have a Starter or Flywheel/Flex-plate issue. Your starter Bendix may not be completely disengaging from the flywheel like it should. I would take it to a mechanic that you trust and have them pull the starter and look at both the Flywheel/Flex-plate, Starter Bendix and solenoid. Hope this helps.

Indicator lights with high pitched squealing sounds.


check the alternator drive belt,it may be loose and squealing.
the alternator itself could be also making a noise.
start the car with the hood open and listen to it.
look if the belt is cracked,loose or wet from oil or water etc.
things like thermostat housings leaking coolant can cause something like that.

Intermittent non-starting caused by high pitched whirring when key turned in ignition


Hello;
The problem you are experiencing is one of two possiblilties. First, the bendix is weak in the starter. Best course of action is to replace the starter. When you pull the starter out, use a pry bar or screwdriver to rotate the flywheel an inspect the meshing teeth of the flywheel. If there is a section that has worn teeth then the flywheel needs to be replaced.
Thanks;
