The car often runs short distances, often does not catch fire, and has to be hit several times. What

Hello! This is called start-up difficulty, and it may generally be caused by the following reasons.

First, the oil pump is not enough to maintain pressure, especially in the morning when the first fire is lit.

Second, the spark plug does not jump well, resulting in a longer ignition time.

Third, the injector is not atomized well, and the oil injected into it is difficult to atomize, so it is also difficult to start.

Fourth, the engine cylinder pressure is insufficient, which is more common in this old car.

It is recommended that you go to the repair shop for a full inspection. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello! The car often fails to ignite and has to be hit several times. Before checking, first, is the oil pressure of the gasoline pump too low?

Whether the one-way valve of the oil pump is poorly sealed and relieved. Second, check whether the throttle body, fuel injector, and idle motor are dirty and blocked. Cleaning is required.

Third, check the spark plug, ignition coil, cylinder wire for aging, cautery, leakage. Resulting in weak ignition ability, which needs to be replaced. Fourth, check the crankshaft position sensor and the electrical plug of the engine computer board, whether the contact is poor?

Hope it helps. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

There is no problem after ignition, there is no problem with high and low speeds, and the car is powerful, and it does not shake, indicating that there is no problem with mechanical and ignition fuel injection, no problem with computer control, and it is easier to accumulate carbon in the engine when it often runs short distances, why? Just on fire is a cold car, the computer board is open-loop control, the fuel injection pulse is wide, in order to heat the car faster, check the air filter, air intake part, throttle part, if the idle speed is stable, it means that there is no problem with the idle motor, focus on checking the air intake system, if there is no problem, it is carbon deposit in the cylinder. Another possibility is the throttle position sensor, which can be measured with a multimeter throttle sensor resistance, which is a sliding potentiometer.

Hello, it is recommended to check whether the oil return valve of your oil circuit is damaged, resulting in the oil circuit pressure relief after the ignition, each ignition needs the oil pump to output fuel from the mailbox to the fuel injector to ignite (you can switch the key several times before the next ignition, do not ignition, switch about 4 times and then ignition, if it is good to play, then it is the oil circuit pressure relief, replace the oil return valve can be) If this is not the reason, then check the spark plug flashover, and the fuel injection of the fuel injector, and deal with it accordingly according to the inspection results.

Hello, it is recommended to check the spark plug and ignition coil, but also to check the problem with the battery, if you think it is appropriate, mine.

Hello, check under the spark plug, if my reply is helpful to you, please set it to the best, thanks!!

There are many reasons why you can't get a taxi.

Your glitch should be accidental. Is it that all mornings can't be sent? Most of them should be caused by poor contact of the line plug.

When you go to the 4S test. You're going by car. In other words, the fault was not checked when it was reproduced.

If possible, use the detector to check again in the morning. The most important thing is to check when the fault light is on. Check one and one accurate.

In addition, do not start the car in the morning after opening the key. Listen carefully to the gasoline pump inside the tank to see if there is a working turning buzzing sound.

You leave it overnight, and the temperature is low at night, so the fluidity of the oil is not very good, and in the afternoon, the temperature becomes high, and the fluidity of the gasoline is better, and it is naturally easy to hit, and it feels like it's a small problem with the oil point of your carburetor, and this will not happen when you wash it.

Turn on the power first to warm up and then start, if you can't ignite, you can try to tap the throttle when igniting (mine occasionally has this situation, just click a foot of the throttle, ours are all electronic throttle, I guess it's the circuit reason,), my C30 also has the same problem, this is an expedient solution that I figured out myself, I hope it can help you.

The motorcycle does not catch fire for any reason.

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 not being ignited, and all vehicles that cannot ignite the mixture cannot be started.

Fuel injection system: It may be in the fuel injection system, the fuel injector is faulty, the fuel supply pressure of the gasoline pump is insufficient, and the fuel injection nozzle line is faulty, so the vehicle cannot be started.

Starting system: It may be that the battery in the starting system is damaged and does not have enough power to drive the starting motor, so the vehicle cannot start, and another may be caused by damage to the starting motor.

My car only appeared in this situation a while ago, and I can play for the first time every day, and sometimes when I am stuck in traffic or walking on a bad road, because of the poor coordination under my feet (it seems to be), the engine suddenly turns off, and I can't hit for half a day, but after a while, I can play again. But if you drive normally, it won't turn off, I went to the repair shop to replace all the spark plugs, cleaned the throttle injectors, and changed the oil, three filters or something, and maintained the whole thing, but the problem has not been ruled out. I couldn't find a problem with them when I went to the garage again.

What is the reason for this? Help me.

It would be nice to replace it with a new car starter, commonly known as a motor.

The biggest possibility is that the spark plug is aging.

If you hit the speed of the train and raise the throttle yourself, there will be unstable belt speed, and black smoke will come out of the back, don't ask me how I know.

Go and check the automotive crankshaft sensor.

It may be a spark plug or something that is not in good contact.

The initial suspicion is that it is a battery problem, the power is insufficient due to power loss, and the engine speed is not enough when starting the car, so the car cannot be started. The car battery is broken and cannot be charged, it is recommended to replace the battery.

When the engine starts, the starter needs to work, the oil supply system needs to work, and the ignition system needs to work, all of which are inseparable from electricity. If there is a problem with the circuit, that will also cause the engine to fail to start.

After starting the engine, the generator will supply power to the electronic equipment of the whole car, and the generator will also charge the battery. Generally, the battery life of a car is 3 to 4 years, but the battery of many cars does not last that long and breaks, which is caused by the owner's incorrect use habits.

Do not use the electronic devices in the car for a long time, do not turn on the air conditioner, and do not turn on the headlights when the engine is not started.

The battery is dead, 1, test what is the starting voltage, the battery voltage cannot be lower than 10 when starting, 2, when idling, the generator works, whether the voltage is 12V, whether the battery can be charged normally.

Summary. The reasons why the car cannot catch fire in the morning are: 1. The car cannot fire in the morning may be due to insufficient battery power, the output voltage of the start in the morning is less than 12 volts, and the speed of the starter cannot be reached, so check whether the battery electrolyte needs to be replenished.

It is generally recommended to replace the battery in time after 2 years. 2. Human factors cause failure to ignite, such as frequent start of the vehicle, the battery is easy to be damaged due to long-term high-load discharge, resulting in failure to ignite. 3. Too much carbon deposition in the vehicle will also cause the vehicle to fail to ignite, and often running at high speed can reduce carbon deposition.

4. In the morning, the engine temperature is low, the viscosity of the lubricating oil increases, the volatility of the fuel becomes worse and the working capacity of the battery is weakened, which leads to the failure to ignite. In winter, it is better not to store the car in the open air, but to park it in a garage with heating equipment. If you choose to park in the open air, you should also place it in a place where the sun can easily reach it.

This heats up faster and is easier to start. After 30 seconds to one minute after the car starts, but at this time do not drive at high speed, should be kept at a low speed, about 3-5 minutes, the speed is generally kept below 2000 rpm, and then resume normal driving after the engine temperature rises to the normal working temperature.

The car does not catch fire in the morning, but it does in the afternoon. What is the reason for this?

The reasons why the car cannot catch fire in the morning are: 1. The car cannot catch fire in the morning may be due to insufficient battery power, the output voltage of the start-up in the morning is less than 12 volts, and the speed of the starter cannot be reached. It is generally recommended to replace the battery in time after 2 years.

2. Human factors cause failure to ignite, such as frequent start of the vehicle, the battery is easy to be damaged due to long-term high-load discharge, resulting in failure to ignite. 3.

In winter, it is better not to store the car in the open air, but to park it in a garage with heating equipment. If you choose to park in the open air, it should also be placed in a place where the sun can easily shine. This heats up faster and is easier to start.

After 30 seconds to one minute after the car starts, but at this time do not drive at high speed, should be kept at a low speed, about 3-5 minutes, the speed is generally kept below 2000 rpm, and then resume normal driving after the engine temperature rises to the normal working temperature.

There was no fire in the morning and afternoon.

The reasons why the car cannot catch fire are: 1. The car battery loses power; 2. The temperature is low, and the viscosity speed of the source oil of the automobile containing the mountain ruler is reduced; 3. There is a problem with the ignition system; 4. The amount of fuel in the car is insufficient; 5. There is a lot of carbon deposition inside the vehicle engine; 6. The fuel pump is damaged, resulting in the fuel in the fuel tank being unable to participate in combustion. ”

Man-made reasons.

Type 1: The battery is dead. It may be due to the loss of power or the expiration of the battery life due to the long-term headlights have not been turned off, and it is generally recommended to replace the battery in time after 2 years.

In addition, the installation of xenon headlights, high-power audio, etc. are also the causes of vehicle circuit failures. The situation of the vehicle without power is easy to check, just press the horn to know.

Type 2: The gear is wrong. When the automatic transmission car starts, the gear must be placed on the P or N gear, if it is placed on the R or D gear, it will not ignite. There are also some manual transmission cars that will not catch fire if you don't step on the clutch.

Reasons for vehicle use: improper oil, no antifreeze, excessive carbon deposit.

In addition to the reasons for improper human operation, there may also be motor failure, or oil pump oil supply, fuel injector problems, sensor failure, etc., encountering these more complex situations, need to be dealt with by professionals. However, pay more attention to the following items when using a car to avoid these complications.

Is there a warm-up for a taxi? Does the taxi turn the motor but the engine doesn't?

Summary. Hello! The reasons and solutions for the car to catch fire after running for half an hour are as follows:

1. If the car battery loses power, you can find other vehicles to take the power to rescue, and you need to turn off the electrical appliances on the loss car before taking the power, so as to avoid a short circuit in the vehicle circuit caused by the negative pole of the battery due to negligence, and damage to the electronic equipment of the vehicle. 2. If the car can not be started, it may be that the wire is not thick enough, generally when buying a car wire, you should choose the best quality assurance wire, try to choose a thicker, outer diameter of at least 10mm. 3. The car may not be able to start the charging time enough, and it is generally necessary to start the rescue vehicle to run for a period of time after taking the power, wait for about 5-10 minutes, and then start the vehicle with power loss.

If it can be started, the car needs to continue to run for about 30 minutes to allow the generator to charge the battery. 4. If it still can't start, it may be a car engine failure and needs to go to a repair shop or 4S shop for maintenance. 5. If the battery is used for too long, vulcanization may occur.

If the vulcanization is not serious, the battery can be charged with a small current, which generally needs to be charged for more than 12 hours. If the vulcanization of the battery is severe, the electrolyte needs to be replaced before charging.

Is it time to change the battery?

Hello! The reasons and solutions for the car to fail to ignite after running for half an hour are as follows: 1. If the car battery loses power, you can find other vehicles to take the power to rescue, and before taking the power, you need to turn off the friendly electric appliances on the loss tram, so as not to connect the positive and negative poles of the battery due to negligence, resulting in a short circuit in the vehicle circuit and damage to the electronic equipment of the vehicle.

2. If the car can not be started, it may be that the wire is not thick enough, generally when buying a car to take the wire to touch the state, you should choose the best quality assurance wire, try to choose a thicker, outer diameter of at least 10mm or more. 3. The car may not be able to start the charging time enough, and it is generally necessary to start the rescue vehicle to run for a period of time after taking the power, wait for about 5-10 minutes, and then start the vehicle with power loss. If it can be started, the car needs to continue to run for about 30 minutes to allow the generator to charge the battery.

4. If it still can't start, it may be that the car is noisy and knows the engine failure and needs to go to the repair shop or 4S shop for maintenance. 5. If the battery is used for too long, vulcanization may occur. If the vulcanization is not serious, the battery can be charged with a small current, which generally needs to be charged for more than 12 hours.

If the vulcanization of the battery is severe, the electrolyte needs to be replaced before charging.
