car suddenly won’t crank just makes grinding noise

So I started my car and it started perfectly no wierd sounds or anything then I backed up out of my garage amd turned the car off cause the key is needed to close my garage well got back in the car to turn it on and it wouldn't crank just made grinding noises everytime I tried.

My car has 125000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
In all likelihood, the starter has failed. It could be a tooth broke off the starter drive gear or the shaft is not extending fully to make proper contact with the flywheel. If either of these happen, the metal drive gear against the metal flywheel will make a loud metallic sound. Have a certified technician inspect the vehicle to verify the cause and replace the starter if needed.

Most likely, if it is true grinding that you hear, the problem is related to the starter. Causes include the starter not lining up correctly with the ring gear on the flywheel, missing or damaged gear teeth, or a faulty solenoid. Replacing the starter is most often the right solution.
Hearing a grinding noise when you start your car typically isn`t a good sign. The problem usually lies with misaligned gears in your starter, a low battery, or a worn flywheel. While it may be hard to identify exactly which piece is causing the grinding, repairs should be pretty straightforward once you do!
If you hear this grinding noise both while you`re driving and idling, it`s possible that worn-out bearings are to blame. If the grinding noise comes when you shift, it`s likely due to a worn clutch. Grinding when you turn a corner could be due to a CV joint that needs to be replaced or another suspension issue.
The most common reasons a Mitsubishi Eclipse won`t start are a dead battery, an alternator problem, or failed starter.
One of the symptoms of a bad starter is a clicking noise when you turn the key or push the start button. However, a starter can die without making any sound at all, or it may announce its impending death with whirring and grinding noise—so listen up!
The most common causes of grinding noises in automobiles are worn-out brakes, a faulty CV joint, or transmission issues. It`s important to note that, whichever component is causing the grinding noise, it needs immediate repair.
When your engine oil is running low, your engine`s components stop receiving the lubrication they need to function properly. Once this happens, you may start to hear clunking, knocking, ticking, or grinding noises coming from your vehicle`s engine.
Low Battery Voltage –

A dying battery can`t provide enough power to start the car, creating continuous clicking sounds. Low battery voltage can also cause the starter motor to turn slower than usual, resulting in a grinding noise.

You`ll receive a warning squeal as the pads wear away–right before the metal backing plate starts rubbing against the brake disc. This causes a very loud grinding noise (metal on metal) whenever you put your foot on the brake. If it gets to this stage, your car is now dangerous to drive.
Why won`t my car start but I have power? If you attempt to start up your car but the engine won`t turn over and the dashboard lights up, then you most likely have an issue with your battery. You could have a damaged or corroded battery terminal, which is stopping the engine from starting up when you fully turn the key.
All Mitsubishi systems from the Mitsubishi 6000 BTU mini split to the 42,000 BTU mini split have at least one wireless remote control. These remote controls have a reset button at the bottom under the panel. Pressing the reset button ensures the remote is working correctly.
When you have a bad starter motor, there are two ways to crank up your engine: Jump-start your car. Push-start your engine.
Most of the time, if you hear scraping and grinding, it can be attributed to one of two main issues: Worn-out brake linings. Worn-out wheel/hub bearings.
If you are getting a grinding noise from the front wheels when driving then the most common cause is the brakes are worn causing the brake pads backing plate rubbing on the rotor metal to metal. Have you brakes inspected to see if just the one side is worn down indicating the caliper is sticking.
Push-start the vehicle if you have a manual transmission.

Once you`ve got some speed going, release the clutch and your car should start. Press the clutch back in and give your engine some gas and you`re good to go! This will definitely work with a bad starter, but it could also work with a bad battery.

Alternators can go bad suddenly, or slowly over time. If your alternator is slowly going bad over time there are some warning signs you can look out for.
If you hear a whine or the sound goes fuzzy when you hit the gas, your alternator is probably failing. If the vehicle won`t crank or start but the headlights are still working, look to problems with the starter or other parts of the engine.
Ignition system failure occurs when the engine fails to ignite and burn the gas mixture fed into the intake. For whatever reason, sparks are not made quickly enough to light the gas and turn the internal cylinders.
CAUSES OF FAULTY STARTERS: CAUSE OF FAILURE

Electrical connections faulty. Solenoid switch (engaging relay) stiff or faulty. Electric motor damaged electrically. Single-pinion gear, starter pinion or freewheel damaged.

Inspect the flywheel – over time the flywheel can become cracked, worn or even lose its teeth, impacting efficient engagement with the pinion gear on the starter motor. If you continue to force the starter motor to work with a broken flywheel, it will quickly diminish the lifespan of the part.
Seized car engine symptoms:

Fumes/smoke: since the engine can`t turn over, fumes, smoke, and even fire can happen – all of which are a sure sign of an engine seizure. Nothing: the most tell-tale sign of a seized engine is when nothing happens. When your car won`t start no matter how hard you try.

When there`s not enough oil, moving parts within the engine do not get the lubrication they need. This allows them to make physical, metal-to-metal contact, which can cause a light tapping or knocking sound.
Should your vehicle`s engine run low on engine oil it could cause it to make a loud “ticking or tapping” noise. This noise is caused by an insufficient amount oil being pumped into the top part of the engine. A simple check of the engine oil level will help you determine if the system is low.

Car makes grinding noise – 1996 Chevrolet Corsica
ANSWER : Hey there, thanks for writing in. I would have a professional mechanic check out the constant velocity joints on your vehicle. One or more of them may be worn enough to cause the noises you describe. S/he can diagnose and replace any failed CV joints.

car suddenly won’t crank just makes grinding noise
ANSWER : In all likelihood, the starter has failed. It could be a tooth broke off the starter drive gear or the shaft is not extending fully to make proper contact with the flywheel. If either of these happen, the metal drive gear against the metal flywheel will make a loud metallic sound. Have a certified technician inspect the vehicle to verify the cause and replace the starter if needed.

Car won’t crank when it’s cold and now won’t start at all
ANSWER : Hi there:

Usually this issue is cased by low cranking amps inside the battery. If you’ve recently had the battery replaced, it’s possible that an electrical component that makes up the charging system might be damaged or faulty. It’s also quite possible that the main electrical relay or the starter relay is giving you fits. To know for certain what the exact issue might be on your 1989 Toyota Camry, you should have a professional mobile mechanic complete a car is hard to start inspection, so they can pinpoint the source of your issues and recommend the right repairs.

car won’t start.
ANSWER : A possibility is a faulty ignition switch. If the switch opens after the car starts, the engine will shut off. But, that is just a possibility and a diagnostic would have to be performed to rule that in or out. Be sure you have a fully charged battery that passes a load test. Starters motors can display intermittent operation if they are faulty. With a fully charged battery, if the starter motor does not run that signifies an electrical problem in the starter circuit (includes the ignition switch) or a problem with the starter motor itself. If there is power to the starter motor and yet it doesn’t run, the starter is condemned and replaced. Alternatively, if there is no power to the starter, or there is a big voltage drop anywhere on the circuit to the starter, then the circuit has to be traced until the fault in the circuit is found. Notably, faults can include high resistances, due to corrosion, wire strand breaks, or loose terminals, which can only be diagnosed using a voltage drop test. Regardless of what the underlying cause of the no start condition is, if you desire that a certified mechanic resolve this promptly, please simply request a no start diagnostic and the responding mechanic will get it diagnosed and repaired for you. Please let us know if you have further concerns or questions as we are always here to help you.

Car stopped suddenly and won’t start again, makes the noise to start but won’t fire up
ANSWER : Hello. If the engine will not even crank over then I usually start by trying to crank the engine over by hand. If it cannot be turned then there is a serious engine problem and the engine has failed. It is common for the timing chains to fail on this engine. At one point Mini was even changing them for free. It can also be a bad sensor or a failure in the fuel pump so further testing will need to be done with a compression test also. The fact that the engine does not turn will be the first spot to diagnose as that can even be caused by a bad battery. If you need help having this repaired, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the stalling issue and have it corrected properly.

My car makes a really annoying noise and sometimes dies right after
ANSWER : Hi there. From the description you have provided your vehicle’s moaning noise and intermittent stalling problem could be any number of things. It could be a failed alternator diode making the moaning noise and affecting the idle.

A failed alternator diode(s) allows voltage to flow both directions or no flow at all resulting in noise heard and erratic electrical operation. It could be a faulty idle air control valve. The idle air control valve can make noise and would account for the erratic idle and sporadic dying. It could be an accessory component, such as an A/C compressor, serpentine belt tensioner, or idler pulley, power steering pump making noise and placing undo load on the engine at idle. If you would like to have this done, a certified professional from YourMechanic can come to your car’s location to diagnose the noise and stalling issue.

Switched to 4WD – did fine for a little then started making grinding noise. Now car won’t move and the 4WD light is blinking.
ANSWER : Hi there. If the 4WD light is blinking and you hear a grinding noise when the transmission is in drive or reverse only, then the transfer case has either broken the fork inside the case or the syncronizer jammed up and is grinding the gears inside the case. If the noise is not coming from the transfer case, then the front differential could be damaged. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your 4WD not working issue.

The car has no power, the ignition relay keeps making a clicking noise, and the car won’t start
ANSWER : I suspect you have a dead (or very low) battery, a failed alternator, and an electrical circuitry problem as well. It may be hard to tell which came first if there is wiring damage already. The clicking you hear is likely the starter solenoid not getting enough power because of a dead battery.

If the car shut down while driving, that is usually an indicator that the alternator is not charging the system. Once you have jumped it off, it should continue to run on the alternator. The failure to run more than 10 mph and the smoke from the engine compartment suggest very low system voltage and additional wiring problems sapping all the electrical system’s power.

I would recommend having a professional mechanic, such as one from YourMechanic, perform an inspection to determine why the battery will not hold a charge and assess any additional problems with the alternator.
