What is the reason why the car can t start?

The reasons why the car can't start are: the car is out of gas, the car battery is out of power, the car is seriously carbonized, the car exhaust pipe is blocked, the battery problem caused by environmental factors, etc., anyway, most of the reasons are because of the car battery. It is definitely a problem for the car to start when it runs out of fuel, which is also a common mistake made by many careless car owners, so it is necessary to check the fuel of the car before departure, and if the fuel is insufficient, it needs to be replenished in time to avoid the situation that the car cannot be started because of insufficient fuel.

The reasons why the car can't start are: 1. The car is out of fuel, and the fuel of the car needs to be tested, and the fuel is insufficient and needs to be replenished immediately to prevent the car from starting due to insufficient fuel; 2. The car battery is out of power, the improper use of on-board electrical appliances or forgetting to turn off the headlights after driving at night will affect the battery power loss, resulting in the situation that the car cannot be started due to the battery being out of power; 3. The carbon deposition of the car is serious, and the unscheduled maintenance of the car will affect the use of the car, and there is a trembling vibration when the car is idling; 4. The exhaust pipe of the car is blocked, the exhaust is blocked due to three-way catalytic crushing or the exhaust pipe is deformed by external force and the blockage is caused by the blockage, which will cause the car to fail to start.

The reason why the car can't start is usually due to insufficient power due to battery damage, poor contact of the electric fuel pump motor, damage to the ignition module, and failure to jump the spark plug due to damage to the ignition module.

There are many reasons why the vehicle cannot be started, and it is recommended to troubleshoot it in time. The following is an analysis of the specific reasons why the car cannot be started: 1. The battery loses power

Because the voltage at startup is lower than the minimum voltage for the computer to work, the engine computer does not work and cannot be started. In this case, the battery should be recharged, or replaced. Spark plugs cannot be ignited:

The spark plug itself is easily damaged, the high-voltage line is short-circuited, etc., resulting in the spark plug can not be ignited, and the other is that the spark plug of poor quality is also the reason for the failure to start normally, in this case, it is recommended to replace the spark plug.

If the car doesn't start, it may be related to your battery, or it may be your spark plug failure. If the battery is dead, then it will definitely not be able to start the car.

If the car is out of fuel, the fuel of the car needs to be tested, and the fuel is insufficient and needs to be replenished immediately to prevent the car from starting due to insufficient fuel;

The car battery is out of power, the improper use of on-board electrical appliances or forgetting to turn off the headlights after driving at night will affect the battery power loss, resulting in the situation that the car cannot be started due to the battery being out of power when using the car;

The carbon deposition of the car is serious, and the irregular maintenance of the car will affect the use of the car, and there is a trembling vibration when the car is idling;

The car exhaust pipe is blocked, the three-way catalytic crushing causes the exhaust pipe to be blocked, or the exhaust pipe is deformed by external force and causes the blockage to cause the car to fail.

If the car can't start, first check whether it is a circuit problem, whether the car battery is sufficient, and then ** plug, if there is no problem, then we will check the oil circuit to see if the oil is supplied. Whether the oil pump is not working or not is generally these two reasons.

If the car battery is damaged, the engine will not start, you can contact the car repair shop, or the insurance company will provide free rescue.

There are two reasons why the car can't start, the first is that there is no power in the battery, and the other is that the car line is not connected.

It is recommended to check the spark plugs, batteries, oil pumps, oil, many reasons can cause the vehicle not to start.

If the pneumatic car can't start, it is caused by the engine running out of power or not catching fire.

What is the reason why the car can't start? I think if the car doesn't start, it's definitely because of the spark plug. Or if there is a problem with the motor, you can drive to the place where the car is repaired and repair it.

The car can't start, I think it's possible that the temperature is too low, so it may not be able to reach the point where it starts, so there may be no way to start, so there may be direction.

There are many reasons, the battery is dead, there is no gas, electrical appliances are faulty, and so on.

If you haven't changed the battery, it's been almost 5 years, and the battery can almost be replaced with a new one, and you can go to the auto parts city to get a new battery again, rest assured, it's not a big problem, it should be replaced, satisfied, thank you.

Remember why it can't be started? If the car doesn't start, it's usually the reason for the starter, or your fuel tank is out of oil, you go to the repair shop to check it, and the problem is solved.

What is the reason why the car can't start 1. It's out of gas:

It is definitely a problem for the car to start when it runs out of fuel, which is a mistake that many careless car owners will make, so you need to check the oil of the car when driving, and if there is a shortage of fuel, you need to add it in time to avoid the situation that the car cannot start because of insufficient fuel when driving.

2. The battery is out of power

Some careless car owners use electrical appliances improperly when driving, or forget to turn off the headlights after driving at night, resulting in a battery loss overnight, and the car cannot be started due to the battery running out of power when driving.

3. Serious carbon deposition in automobiles:

After the car has serious carbon deposition, it will also affect the normal start of the car, and there may also be shaking when the car is idling, the owner can relieve it by cleaning the throttle valve or cleaning the intake pipe, and pay attention to their driving habits when driving daily, which can also reduce the generation of carbon deposition in the car.

4. Blockage of automobile exhaust pipe:

After the car exhaust pipe is blocked, it is difficult for the car to start again, which is not blocked by human causes, but due to the exhaust blockage caused by three-way catalytic crushing or the deformation of the exhaust pipe caused by external force, so when driving at ordinary times, it is necessary to conduct a comprehensive inspection of the car to avoid various faults when driving.

The car started unclear.

There are many reasons why the car cannot start, such as insufficient battery voltage, damage to the starter, problems with the fuel supply system, problems with the ignition system, etc.

The engine needs fire, oil, and air to start properly, and the starter is also needed to drive the engine to turn. Then both the ignition oil supply and the starter need electricity. Therefore, when the battery is out of power or the voltage is insufficient, the engine will not start.

If the battery voltage is normal, then the normal gasoline cannot be guaranteed after the gasoline pump has a problem**, so the starter can not start smoothly.

If both the oil supply system and the battery are normal, a faulty ignition coil or a faulty spark plug will also cause it to fail to start.

Starter damage is not often encountered, and the starter is generally not damaged, because the starter only works for a few seconds each time it starts, so the working time of the starter throughout the year only adds up to a few hours.

As the electrode gap increases over time, and carbon deposits may occur in the spark plug, a new spark plug will need to be replaced.

It is recommended that all riders use instruments to measure the voltage and internal resistance of the battery during the usual maintenance, if the voltage and internal resistance do not reach the specified value, this means that the battery should be replaced.

When replacing the battery, you can choose the AGM battery, which has a longer service life and better charging and discharging performance than ordinary lead-acid batteries. (Photo by Q&A: Q&A called the beast) @2019

There are several reasons for this:

First, the battery loses power.

Third, the ignition system is not in good working condition.

Extended Materials. 1 Produces enough voltage to break down the spark plug gap.

The voltage required for the spark plug electrode to break down and generate a spark is called the breakdown voltage. The secondary voltage generated by the ignition system must be higher than the breakdown voltage in order for the spark plug to skip fire. The magnitude of the breakdown voltage is affected by many factors, the main of which are:

1) Spark plug electrode gap and shape.

The larger the gap between the spark plug electrodes, the higher the breakdown voltage;

The tip of the electrode is angular and the required breakdown voltage is low.

2) The pressure and temperature of the gas mixture in the Cong Jing cylinder.

The higher the pressure of the mixture, the lower the temperature, the higher the breakdown voltage, 3) the temperature of the electrode.

The higher the temperature of the spark plug electrode, the lower the density of the gas around the electrode and the lower the breakdown voltage.

2 The spark should have sufficient energy.

When the engine is working normally, only 1 5 mJ of spark energy is required because the temperature at the end of the mixture compression is close to its autoignition temperature. However, when the mixture is too thick or too thin, when the engine starts, idles, or when the throttle is opened sharply, a higher spark energy is required.

3. The ignition time should be adapted to the working condition of the engine.

First of all, the ignition system should be ignited in the order in which the engines work. Secondly, ignition must be carried out at the most favorable moment.

The reasons why the car cannot start are: exhaust pipe freezing, valve gluing, ignition system working in poor condition, gasoline flow blocked, battery power loss.

1. The exhaust pipe is frozen.

The appearance characteristics are fog cylinder pressure, normal oil supply and power supply, and no car. This situation is easy to occur in the use of particularly low frequency of vehicles, such as the home is particularly close to the unit, the water vapor after the combustion of the engine freezes at the muffler of the stuffy pipe, the ice of yesterday is not finished for short-distance driving, and today's ice is frozen, and the time is long, affecting the exhaust, and it is serious and cannot be started.

2. Valve gelding.

Winter vehicles, especially after the use of unclean gasoline, the non-flammable gum in the gasoline will accumulate near the intake, exhaust valves and combustion chambers, which will cause difficult start-up or even no fire in the cold morning of the elimination bend.

3. The ignition system is not in good working condition.

In especially cold weather, due to the low intake temperature, the fuel is not atomized well in the cylinder, and if the ignition energy is insufficient, the result will be flooding, that is, too much fuel accumulates in the cylinder, exceeding the fire limit concentration and cannot be landed.

4. The flow of gasoline is blocked.

The performance is characterized by no oil pressure in the engine oil supply pipe. This situation usually occurs in the morning when the temperature is very low, and is caused by long-term dirt in the fuel line. When the temperature is very low, the water mixes with debris and the fuel line is blocked, and as a result, it cannot be started.

5. The battery loses power.

Its performance is characterized by the starter starting to rotate but the speed is not enough, that is, it is weak, and then the starter only clicks and does not turn. The low temperature in winter and the forgetting of individual electrical equipment will cause the vehicle to be unable to start, especially in the winter for long-term short-distance low-speed use, the battery voltage will be lower than the rated value, and the starting and normal operation of the cherry blossom will not be possible.

The car may not start because the battery is out of power and cannot start, or the fuel pump is damaged.

The vehicle battery has not been replaced for a long time or is due to discharge, resulting in the vehicle not responding when starting, and the starter cannot work. In this case, you can turn on the ignition switch and turn on all the lights to see if the lights are on to determine whether it is caused by the battery power loss. If so, you need to find a battery to power the vehicle, so that you can start the vehicle.

If the fuel pump is damaged, the fuel in the fuel tank cannot participate in the combustion**. The way to judge is to turn on the ignition switch, you can listen to the sound of whether the fuel pump is working in the car, and if there is no need to replace the fuel pump to solve the problem. If you are in a hurry, you can use a hard iron rod or something else to tap the bottom of the tank.

If the fuel pump is not completely damaged, it should be able to start the vehicle. Of course, it is also possible that the fuel pump control unit or relay is damaged.

What causes the car to not start

2. The starter is faulty. If the starter fails and cannot drive the engine flywheel to rotate, the vehicle will not start, and you need to go to the 4S shop to repair the starter.

3. The battery is out of power. After stopping and turning off the ignition, the driver forgets to turn off the headlights, causing the battery to lose power, and the vehicle cannot be started and needs to be charged.

4. The engine belt is cracked. When the vehicle cannot be started, the driver can check whether the belt of the engine is cracked, and if the belt is cracked, the engine belt needs to be replaced.

5. The steering wheel is not back to right. When parking, the driver did not return to the steering wheel, resulting in the steering wheel being locked and sold, and the driver needed to turn the steering wheel hard and twist the key at the same time to unlock the steering wheel and start the vehicle.

Hello dear <>, happy to answer for you. The ignition of the car may not be ignited due to the following reasons: 1. Ignition system: it may be that the spark plug of the vehicle is faulty, and the ignition module is faulty, resulting in the spark plug being unable to ignite, and all vehicles that cannot ignite the mixture cannot be started; 2. Fuel injection system:

It may be that in the fuel injection system, the fuel injector is faulty, the fuel supply pressure of the steam number potato pump is insufficient, and the fuel injector line is faulty, resulting in the inability to inject fuel, so the vehicle cannot be started; 3. Starting system: It may be that the battery in the starting system is damaged and there is not enough power to drive the starter Minbiying motor, so the vehicle cannot be started, and there may be a damage to the starting motor. <>
