Won’t start just cranks

I was driving and was hearing a stange noise I haven't heard before as if something was loose under the hood?(rattling of some sort) and when I stopped at a red light, my engine just shut off. Everything else works fine (lights, radio, etc.) I try to turn it over (it was making a stange noise) and won't start, just turns. But when I was driving and switching gears, it sounded and lil weird, noting I heard before.

My car has 150000 miles.
My car has a manual transmission.

Experienced mechanics share their insights in answering this question :
Hello. I would start by checking the fluid levels in the engine. I would then see where the noise is coming from as it sounds like the starter may be trying to engage. If the alternator went bad and caused the battery to discharge then this will happen. Start by checking the battery at this point. If the battery is low then it needs to be charged and retested. If the battery is fine then the alternator needs to be checked. If these components are fine then the voltage at the starter needs to be checked. If there is voltage to the starter when trying to crank it and it still does not work then the engine may have seized.

If I suspect that then I attempt to crank the engine over by hand. If that cannot be done then the engine needs replacement. If it can then further diagnosis would need to be done. If you want to have this no start diagnosed consider YourMechanic, as a certifed mechanic can come to your home or office.

The most common reasons a Saturn Vue won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
Hi There, This can happen for a few different reasons such as a faulty or dirty mass air flow sensor, a faulty fuel pump relay or in some cases a bad ignition coil.
The most common reasons a Saturn Ion won`t start are a dead battery, an alternator problem, or failed starter.
Damaged CV joint: The most common cause of a clicking or popping sound from the wheels is a broken CV joint. The CV joints, which stand for Constant Velocity, are essentially the wrists of your vehicle`s steering system.
The most common reasons a Saturn Vue key won`t turn are a binding steering column/lock, an ignition switch issue, or a problem with the ignition key.
Defective ignition switch

If you know your battery is working properly, but your car doesn`t turn over on the first few tries, you might have a problem with the ignition switch. You can try to narrow down the cause of your issue by turning on your headlights.

The most common and obvious reason your car may start then die is the fuel shortage in your engine. This happens because there`s not enough fuel in the fuel rail, and there`s no fuel pressure to keep the engine alive. The reason isn`t always you forgetting to fill up your gas tank.
Common culprits include a faulty fuel pump or fuel pump relay. A clogged fuel filter or bad fuel pressure regulator is also common on return-type fuel systems. Another often overlooked problem is the vehicle simply being out of fuel. Sometimes the fuel gauge breaks or is inaccurate.
While a Saturn can experience the same issues as any other car, there are a few recurring issues that Saturn owners have reported over the years. Saturn owners are more likely to deal with transmission issues, gas cap problems, power steering issues, and powertrain control module malfunctions.
Common reasons for this to happen:

Loose connections at the positive and negative battery terminals. Very dirty or clogged air filters can also cause your engine to underperform. Loose timing belts are another likely cause. A mechanic will check these and replace them if they appear loose and worn.

It might be a battery or alternator problem.

Perhaps your battery`s dead, or your alternator, which charges the battery, isn`t working correctly. If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn`t have enough juice to stay powered.

The most common reasons a Saturn Vue engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.
ignition device. fuse, also spelled Fuze, in explosives technology, device for firing explosives in blasting operations, in fireworks, and in military projectiles.
Loose wiring, corroded connections, damaged starter components, oil leaks, and a bad relay or fuse are some of the reasons why a starter can fail. As the driver turns on the ignition switch, a current for the starter should flow and get the engine running. If not, the starter might be faulty and require replacement.
Bad Sensors

One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.

If you don`t hear clicking when you start the engine, the problem may be a dead battery. If you hear clicking, but the engine doesn`t crank, the starter might not be getting enough electricity. Using your owner`s manual and a voltmeter, you should be able to test functionality.
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
But if the alternator isn`t functioning properly and the battery dies, your car may eventually lose power and stall or completely shut off. So, can your battery die while the car is running? Absolutely. And oftentimes, this issue is caused by a combination of alternator and battery problems.
If your headlights can turn on, but your car won`t crank, that means that your battery is charged, but either the starter or ignition is the problem. If the starter or ignition is the problem, a starter engine can be jumped by using a charged battery.
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
The starter relay is one of the most critical and often overlooked components in any vehicle ignition system. The starting relay is a small electrical device located in the starting circuit of a large current motor.

ANSWER : Hi there:

If you checked the oil and determined that there was no oil in the car, it’s quite possible that some internal engine components have seized up; which means there might be serious engine damage internally. Before you attempt to crank it again, please contact a professional mobile mechanic to complete a car is hard to start inspection; so they can pinpoint what is the source of your issues before it causes more damage.

The car crank but won’t start
ANSWER : Hi there. This does sound like an issue with the wiring. If the check engine light is coming on every now and then this means that when it does not come on there is no power to the computer. This can be the wiring harness issue or an ignition switch problem. I would have to test for voltage to the computer when the problem is occurring to be able to find where the issue lies. If you need assistance, a certified YourMechanic technician can be dispatched to your location to inspect your vehicle’s non-start issue and suggest any necessary repairs.

72 Chevelle cranks but won’t start and has to be flooded but smell no gas
ANSWER : Gasoline is generally not usable after 3 to 6 months. If gasoline has been stored in the vehicle for a lengthy time, the problem is likely that there is just simply nothing to combust. The volatile components in the gas have evaporated and other compounds in the gas have turned to varnish and gum, possibly plugging up the carburetor. If the tank was drained though and the fuel in the fuel system is fresh, please simply request a no start diagnostic and the responding certified mechanic will pinpoint the cause of the no start condition. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Vehicle won’t start, once it’s jump started it only stays running until you turn it off, then it work start again without jumping.
ANSWER : Hi there. There could be two problems here. It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery. The second problem could be that your alternator is bad and not charging your battery, in this case you will need to replace your alternator. Both the battery and the alternator can be tested in your car. If you would like to have the car checked for you, a certified professional from YourMechanic can come to your car’s location to diagnose the starting problem and proceed with repairs.

Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.

ANSWER : Hi there. It sounds like you have a failed starter. However, without proper testing there is no way to be 100% sure. I suggest having the battery tested first with a digital battery tester that provides current voltage, cold cranking amps, and state of health. Also inspect for corrosion on the terminals and cables as this will cause excessive resistance and not allow proper voltage/amps to the starter. Other possible failures could be in the wiring harness, relay, fuses, or communication network. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car does not start inspection.

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.
