What's wrong with the engine not starting when the car starts?

The reasons why the engine does not light up are as follows: the battery is insufficient or out of power. For the diagnosis of such faults as the engine not being able to start, the battery should be detected first.It must be clarified whether the battery is insufficient when the engine fails to start, and the battery needs to be charged. The engine start system fails.

The reasons why the car engine can't catch fire: battery failure, spark plug problems, oil line or fuel injector nozzle failure, cylinder pressure problems, throttle valve carbon accumulation, etc.

Battery power loss When the car battery is out of power, it must not be able to start the car, and the battery lacks water, malfunction, long use of the air conditioner for too long and other reasons will cause the battery to lose power. The ignition system fails. The ignition system provides high-voltage electricity to the spark plug to ensure the normal operation of the car.

The reasons why the car can't start are generally: caused by the battery is out of power or the fuel tank is out of oil; the gear is wrong or the steering wheel is locked and the steering wheel is locked and the inability to start; the car circuit or electronic failure, such as spark plug damage, fuse burnout, oil pump failure.

The following are the reasons why the engine cannot be ignited: fuel injector is blocked: In general, the fuel injector blockage is caused by impurities in the fuel that block the fuel injector passage.

Check whether the belt of the engine has been used for a long time and has aged. Therefore, when ignition, the belt slips and cracks, causing the car to not start.

There is a strange sound when the car starts

1. There are many reasons for the abnormal noise when the car starts, including low engine temperature, thermal expansion of the car's ternary catalyst, gearbox failure, engine belt or chain wear, etc. The engine temperature is too low: When the car is cold started, the engine temperature is too low to work normally. It is normal to have some abnormal noises at this time.

2. If the owner is driving an automatic transmission vehicle, when the vehicle is on fire, the owner should take the first step to check whether the gear of the vehicle is successfully suspended. If the automatic transmission vehicle gear is not in P gear or N gear, it will also cause the car to rattle when it starts. .

3. There is a strange sound when starting the carThere are many reasons, including the engine temperature is too low, the thermal expansion of the car's ternary catalyst, gearbox failure, engine belt or chain wear, etc.

4. The reasons for the abnormal sound of the car starting and the solution are as follows: there is a sharp chirping sound at the moment the car starts.

5. There is a strange sound when the car is ignited: this sound may be the closing sound of the valve of the engine gas distribution mechanism. In an engine, the gas distribution mechanism is the most noisy. This kind of sound is the sound made when the intake and exhaust valve is closed, which can generally be heard after activation. Of course, it may also be the sound of spark plugs jumping.

What are the correct operating steps to start the car?

Steps to start the car correctly: 1.After getting on the car, adjust the seat to suit you, and then fasten your seat belt. Start the car, then step on the clutch with your left foot and put it in first gear. Turn on the left turn signal and signal with the horn.

After starting, the gear is put in D gear, slowly release the brake, and the vehicle will move forward. If it is a manual transmission, you need to step on the clutch and start the engine, then hang it into 1st gear, slowly release the clutch, move the right foot from the brake pedal to the accelerator pedal, and refuel slightly. The throttle and clutch are used together, and the vehicle moves forward slowly.

Adjust the seat position Adjust the front and rear positions of the seat, so that the sole of the foot steps on the clutch to the end and has a slight margin. The steering wheel in the hand is based on the convenience of operation. The backrest should be comfortable, but all adjustments should be based on safety.

The correct start-up operation of the automatic transmission is: turn on the power first to complete the self-test;Step on the brake and hang N gear; ignition; hang from N gear to D gear; release the handbrake, raise the foot brake, and start. The reason for this operation is to avoid the need to go through R gear after the p gear catches fire, causing the gearbox to experience a short reverse impact.

Start the engine. Usually, we should observe the indicator light in the dashboard. If the fault light is on for a long time, it indicates that the fault light is abnormal for the parts. The engine should be turned off immediately, the vehicle should be checked and troubleshooted before restarting the engine. Step on the clutch deeply, and step on the clutch pedal with your left foot.

The specific operation steps for starting the car are as follows: before starting the car, it should be in a void, and shake it left and right to ensure that it is in the position of the idle gear. When starting, step on the clutch with your left foot and step on the foot brake with your right foot. Turn the ignition switch to the right with your right hand. After the circuit is turned on, the light on the dashboard will turn on.

Engine shaking when the car starts

Start-up jitter may be caused by the intake system, fuel system, ignition system, and car engine mechanical system. Check the degree of shaking of the engine cylinder, and you can also check the degree of shaking of the oil ruler handle. The stable oil measuring handle is very clear, and the jittering oil measuring handle seems to be double.

The engine has serious carbon accumulation. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

The most common reason for car jitter may be the dirty throttle valve and too much carbon accumulation in the fuel injector.

The most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.
