The car suddenly couldn’t start, it cranks well

I drove my car the other day and stopped it to for about an hour or so. When I was about to continue driving, it would start and run roughly for a short while and turn off. I attempted to start it up again but it did the same thing. It was running roughly while I kept my foot on the gas pedal so that it wouldn't shut off. However, after several seconds it just died out. After that, the car cranks fine but cannot be turned on at all. I suppose that the battery and the starter are working well. I had the hoses and wires checked. This issue happend suddenly and I've never had anything sim
Experienced mechanics share their insights in answering this question :
When a fuel pump fails, it is known to happen randomly and can give the same symptoms you are describing. My first recommendation would be to have your fuel pressure checked by a certified professional to determine whether or not the fuel pressure is within the manufacturer’s specifications. If it is not, the fuel pump and fuel filter will likely need to be replaced in order to resolve this issue.

It is also possible that your ignition coil may have failed preventing any of the spark plugs from firing. I would recommend having your ignition system inspected as well. Ensure that your starting issue is diagnosed professionally as it relates to flammable substances and high voltage electricity. Once the source of the issue has been located, have the parts replaced as necessary in order to maintain the vehicle.

How to Identify and Fix Common car Problems ?

If your brakes emit a sharp grinding sound while braking, it`s likely that the brake disc and the caliper are rubbing together. The sound is usually heard when you stop your car, but you may also feel the brake pedal rumble as you step on it.
A brake pedal that is stiff and won`t depress can be caused by several different things, including air in the hydraulic system, a leak in the hydraulic system, or simply dirt and grime on the pedal. Your car won`t start due to a faulty battery, fuel pump, starter motor, or ignition switch.
If you hear a loud grinding sound when you push down the brake pedal, it`s most likely a result of contact between the rotor disc and part of the caliper, which occurs when your brake pads are wearing down or have already worn down completely.
Batteries. When batteries run low on power, they`ll rapidly alternate between the on and off positions instead of staying on, which could cause something that sounds like grinding. In general, you should replace your battery every 3-5 years.
A common cause of grinding noises under your car are failing wheel or hub bearings. Wheel bearings allow the wheel and tire to rotate and are designed for low friction, while hub assemblies have an additional responsibility of securing the wheel and tire to the vehicle.
Not only does this cause an unpleasant sound, but it can also damage your rotor, reduce your brakes` responsiveness, and lead to brake failure. Grinding from worn-out brake pads and rotors is just one of many brake problems that may reduce your stopping power.
When your brake fluid is dirty or low, it isn`t able to depress your brake pads as efficiently as it should. This can cause uneven wear or even damage to your brake pads, which can cause grinding, squeaking, or squealing noises when you use your brakes.
A malfunctioning Anti-lock Braking System (ABS) can also cause a hard brake pedal. The ABS system is responsible for preventing the wheels from locking up during emergency braking. If the ABS system malfunctions, it may cause a loss of hydraulic pressure, resulting in a hard brake pedal.
The “stiff” gas pedal issue is most likely caused by a dirty throttle body in the air intake system. Cleaning the throttle body should relieve this symptom. The lack of “Drive” selection, unless first selecting “Reverse”, could be a loose or misadjusted shift cable or shift linkage issue.
Your Brake Rotor Needs Replacement

Brake rotor disks that aren`t flat can create squeaky brakes, whereas a worn-out rotor disc will often make a scraping sound. You`ll also be able to feel a warped rotor through your steering wheel.

What is Brake Drag? Brake drag happens when the brake pads or shoes don`t release completely when the brake pedal is released and is typically a result of mechanical issues or hydraulics.
Your Alternator Might Be Wearing Out

When your alternator is starting to wear out it will often make a grinding noise. This is because modern alternators have a decoupler pulley system designed to help you save on fuel, but can make a grinding noise when they are not working properly.

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.
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.
Grinding

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. And if you notice a grinding noise when you brake, your brake pads may be completely worn down to the metal.

Low brake fluid will cause air to fill the gaps in your brake line—leading to soft brakes. Spongy brake pedals can be both terrifying and dangerous—especially if you do not get them serviced at the first sign of an issue.
Brake fluid is a critical component in the hydraulic brake system and stopping would be quite the challenge without brake fluid. In fact, your brakes may not work at all if your brake system is low or out of brake fluid. Hydraulic brake systems require fluid to help increase pressure to stop a vehicle.
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.
Wheel bearings are situated between the axle and the wheel, and minimize friction, allowing for smooth movement while driving. A grinding noise when turning may mean that the wheel bearing is worn out and should be replaced as soon as possible.

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.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

When I go to crank my car the key stays in the start position and the car is constantly trying to crank itself.
ANSWER : First, let’s make sure about some terminology before I proceed. I will assume the motor is actually turning over. If the car is trying to start, the motor has to be turning over or it is not trying to start. This is an important distinction when diagnosing the starting system. As a technician, I go to different parts of the system based on this description.

If the key is stuck in the start position, this is a ignition lock cylinder issue and the reason the starter continues to turn the motor over. If the starter is turning but the motor is not, then the starter is likely the problem. Either that or the teeth on the flex plate are all gone. This would require removing the transmission to repair.

If the car runs intermittently, this can be a big challenge. And it also means the starting system is working. It will need to be diagnosed when it is failing. A working car cannot be diagnosed because there is nothing wrong. Where you park your car should not have any affect. It certainly could be a wiring problem. Wiring problems hide really well and can happen anywhere in the miles of wires that are in your car. Isolating the system that is failing is really important here. At the moment I am unsure which system is failing. Starter system, ignition lock cylinder and or ignition switch electrical or something with the engine control system.

When the car is failing, you need to check for spark and fuel pressure. If neither is present, this is a clue. Usually the crank sensor will do this. Does your car have a tachometer? If so, does it move at all when cranking. This is a clue whether or not the cam and or crank sensor is working. Is there a Check Engine Light on with the key on? If there is a Check Engine Light, the code or codes can be used for specific diagnosis.

All of these concerns will send you down a diagnostic path. Be sure not to confuse yourself by misinterpreting multiple system failures. If the key does stick in the start position, this would be the first problem to solve. After that, does the motor actually turn when the starter turns? After that, the question of "Why won’t it start?" is first answered by finding what the motor is lacking. Fuel, spark etc… Good luck.

If you need assistance with these checks, contact a certified mechanic who has the tools and experience needed to properly diagnose this starting issue with your car.

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.

Map sensor car won’t start up good ?
ANSWER : Your MAP sensor is an important input for your computer. It helps determine the load on the engine to calculate the correct amount of fuel to inject. It sometimes takes a few seconds for the vehicle to realize that the sensor is not producing a good signal.

At that point, it will use other methods to determine the fuel rate, such as pre-programmed fuel maps, throttle position, etc. I would suggest replacing the MAP sensor and retesting. If you would like to have it checked first, a certified technician from YourMechanic will be able to scan your vehicle and test components to determine the root cause of your starting issue before making a repair.

My car starts fine but always like once a month it doesn’t start it cranks ok but it will not start if I let it sit for 6 hours
ANSWER : Hi There,
What you are describing sounds like an ignition coil that may be failing. Ignition coils are prone to this type of erratic functioning or heat cycling when they are beginning to fail due to the temperature fluctuations under the hood which ultimately cause them to shut down causing the car to only run after cooling down for 30-40 minutes. Ignition coils are coated with a varnish-like insulation that becomes brittle over time after being stretched then contracted repeatedly The insulation develops small fractures that open when heated and close when cooled. When open, they allow shorting of coil windings and decrease or eliminate the coil’s ability to function. This process will repeat itself continuously until the coil ultimately fails completely and must be replaced. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your ignition system.

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.

car hesitates when trying to start the car ,but when started then i shut car off and start again it will start right up
ANSWER : Hi there:

Sometimes when you have problems starting an engine initially it is caused by a restriction in fuel flow; caused either by clogged fuel injectors or the throttle body that needs to be cleaned. Once the fuel starts to flow and engine warms up, it’s much easier to start. However, it could also be an air filter, EGR valve or other components that causes this issue as well, which is why it’s best to have a professional mobile mechanic complete a car is hard to start inspection so they can pinpoint the source of this issue.

The car is having trouble starting up ,70 percent of the time it starts right up. the other 30 percent, it randomly won’t start its
ANSWER : Hey there thanks for writing in about your 1998 Honda Accord. This could be a few things. A faulty ignition switch, a failing crank sensor, or possibly other faulty sensors could be the cause. To have this taken care of, consider having a certified technician, such as one from YourMechanic, come to your car’s location to diagnose and repair the hard start issue.
