What happens when a car starts and turns off automatically?

The reasons for the automatic shutdown of the car after starting are: serious carbon deposition in the car engine, the car's anti-theft system, ignition switch failure, and low pressure in the car fuel system.

1. Serious carbon deposition in automobile engines

If the engine of the automobile has serious carbon deposit, and the fuel is not effectively burned in the cylinder, the vehicle will turn off after starting. In this case, the carbon deposits of the engine should be cleaned up in a timely manner.

2. Trigger the car's anti-theft system:

If the car's anti-theft system is triggered, the car's engine can start but cannot run normally, so the car will automatically turn off after starting. This situation is generally prone to occur after a new car key is replaced, so be sure to recode the key after replacing the car key or replacing the new battery.

3. Ignition switch failure:

If the ignition switch of the car fails, the car will automatically turn off after starting, and the vehicle fault warning light will turn on. This situation is more complicated, and it is necessary to go to the car repair shop or 4S shop to find a professional person for inspection and repair.

4. The pressure of the automobile fuel system is low.

If the pressure of the fuel system of the car is low, the fuel will not be burned effectively, and the fuel system needs to be checked.

This situation should have nothing to do with the battery, go to overhaul and check it, focus on checking whether there is a problem with the air flow meter, ignition coil, throttle, engine computer motherboard, my friend's old Toyota car is the same as yours, and then a check is that the throttle is dirty, and then the computer motherboard is broken, and the fault is eliminated after cleaning the throttle and replacing the computer motherboard. Hope, thank you.

Caused by the driver's driving technique or a problem with the car itself.

Driver's driving technical reasons: This situation generally appears in driving manual transmission models, low gear high speed, that is, the speed of the car is too low, the gear is high, the speed of the car does not match the gear, it will stall.

There are many reasons for the problem of the car itself, such as the oil circuit system, ignition system, air intake system, and circuit system, and any part of the problem will lead to stalling.

If you usually maintain it on time, the most common reason is that the oil used is unqualified and there are too many impurities, which leads to the blockage of the oil inlet and the unsmooth oil path, which in turn leads to the flameout.

In this case, it is necessary to contact a 4S shop or a professional auto repair shop as soon as possible, so that professionals can conduct an inspection, and only by determining where the problem is, can the symptoms be repaired.

Hello, there are the following reasons: 1. The use of inferior fuel causes the engine to stall due to carbon deposit.

2. The reason for the stalling of the new car (automatic transmission) is mainly caused by the lack of skillful driving skills, and another possibility is the problem of the car engine or oil circuit, but for the new car, the problem of the engine itself is less likely, and most of the reasons are the problem of the oil circuit.

3. Or the use of substandard oil to make the engine carbon collection caused by the flameout.

4. The main reason for the failure of the car to stall in the idle state is due to too much dust in the air, and there is a lot of dirt deposited at the valve core of the idle motor and the throttle seat when the engine is running. The solution to this problem is simple: just clean the idle motor.

5. The reason for starting and turning off the engine is that the clutch is loose too fast, step on the clutch to hang up to the first gear, slowly lift the clutch, when the clutch is in a semi-linkage state, the front of the car shakes, at this time put down the handbrake, the left foot must be stable and don't move, wait for the car to go for a second or two and then slowly lift all the clutch, refuel and shift.

Most of today's car engines are electronically controlled fuel injection gasoline engines, and there are many reasons for idle shutdown, so first of all, we must analyze the symptoms of idle shutdown.

If the engine will stall as soon as it enters idle operation, we call it "no idling", and the causes of this failure generally are: damage to the engine idle motor or the idle motor's wiring; Leakage of the vacuum tube of the brake vacuum booster; Broken membrane of the brake vacuum booster; air leakage in the intake manifold; There is a problem with the idle control module in the engine electronic control unit (ECU).

The reasons for the automatic shutdown of the car after starting are: 1. The oil used is unqualified; 2. The oil circuit is not smooth; 3. The spark plug is faulty; 4. The fuel injector and fuel filter are abnormal; 5. The contact of the line plug is not good; 6. Driving skills are not skilled enough; 7. Short circuit and power failure of the engine or car computer; 8. Loosen the clutch too quickly when starting or going uphill; 9. The oil pressure of the oil pump is too low; 10. The idle speed control system is not working well. The repair steps for the car to turn off automatically are:

1. Turn on the car point switch, observe whether the indication of the gasoline gauge is normal, and see if there is oil in the fuel tank; 2. Check whether the lower circuit is faulty; 3. Check whether the connecting wires of the starter and the battery are connected reliably.

There are several reasons why the car automatically turns off after starting: serious carbon deposition in the car engine, triggering the car's anti-theft system, ignition switch system failure, low pressure in the car's fuel system, etc. The engine of the car has serious carbon deposits, and the fuel cannot be effectively burned in the cylinder, which will cause the vehicle to stall after starting.

In this case, the engine carbon deposits should be cleaned up on time.

The car anti-theft system is triggered, the car engine is locked, so that the engine can start, but it cannot run, and the key is released and the flame is turned off after one or two clicks, and the anti-theft light is on at the same time. This kind of situation usually occurs in Volkswagen Audi models, most of which are because the owner of the car has equipped a key without a chip without authorization in order to prevent the loss of the key, or the key has been knocked to weaken the signal, and the system cannot recognize it. Then there is because the car engine computer or anti-theft system components are not matched after replacement, and the wiring is damaged.

When the ignition line is in operation, there is electricity, and if the key is released, the current will be disconnected and the ignition will suddenly turn off. This kind of situation is usually caused by poor contact of the contacts in the ignition switch, most of which are accompanied by the phenomenon that the instrument panel battery light, oil lamp, engine failure light is not lit, etc. Some of them intermittently produce system failures such as no air conditioning and heating, headlights not lit, and electric doors and windows malfunctioning a while before the failure.

The working pressure of the fuel system is too low, such as low working pressure of the oil pump, oil leakage in the pipeline, low current in the power supply system, damage to the oil pressure regulator, etc. When the working pressure of the fuel system is too low, the gasoline injected by the normal injection time is too little, and the mixed steam formed cannot be compressed and ignited, but during operation, the injection time corrected by the starting program is greatly extended, although the working pressure of the fuel system is too low, the gasoline injected can be compressed and ignited, and the automobile engine can be started. After starting, if the normal fuel injection is transferred, the ignition will be extinguished.

In addition, the oil pump does not pump oil, and in the first dozen starts, it is also the same phenomenon - it can be started, but the ignition is turned off immediately after starting.

This situation should have nothing to do with the battery, go to overhaul and check it, focus on checking whether there is a problem with the air flow meter, ignition coil, throttle, engine computer motherboard, my friend's old Toyota car is the same as yours, and then a check is that the throttle is dirty, and then the computer motherboard is broken, and the fault is eliminated after cleaning the throttle and replacing the computer motherboard. Hope, thank you.

Hello, the car automatically turns off after starting, and the idle speed is too low. The oil supply is not smooth, the spark plug is not ignited, and the starting gear is too high.

Hello, the engine stall after the cold start is generally caused by dirty throttle or air leakage in the intake system and insufficient gasoline pressure.

Hello question, there is no carbon deposit, the bar pressure oil pump, the spark plug, all checked are normal, that is, as soon as the car is cold, it will appear, and it will start, but it will automatically turn off in 3 seconds, and it will be normal until two or three times. I also suspect that it is the engine anti-theft system, what is going on, and I forgot to answer the teacher [handshake].

Ask what kind of practice it should be and how much it will cost.

There may be several reasons for the automatic shutdown of the car engine: 1. Operation errors: especially for novices, such as hanging the wrong gear, such as pressing the brake too hard, such as oil separation coordination problems, etc., or accidentally touching the car key and turning off the car and getting on the car again.

2. The throttle idle motor is too dirty: it mostly occurs when idling, often accompanied by engine shake failure, and when you start again, you can get on the car by lightly stepping on the accelerator and giving some oil. It is recommended to clean the throttle in time.

Summary. Hello friends. There are many reasons for automatic shutdown after starting, mainly including triggering the car anti-theft system, ignition switch failure, serious carbon deposition in the car engine, and low pressure in the car fuel system.

It is recommended to go to the maintenance organization for maintenance as soon as possible, and the maintenance personnel will make accurate judgments through professional diagnostic equipment.

Hello friends.

It is recommended to go to the maintenance agency as soon as possible for maintenance and repair, and the maintenance staff will make accurate judgments through professional diagnostic equipment.

There are many reasons why it automatically turns off after starting. Here are the details: 1

Trigger the car anti-theft system: If the car anti-theft system is triggered, the car engine can start but cannot run normally, then the car will turn off after starting. Workaround:

This usually happens easily after a car key has been replaced, so the key needs to be re-encoded after the car key is replaced or the battery is replaced. 2.Ignition switch failure:

If the ignition switch of the car fails, the car will automatically turn off after starting, and the vehicle fault warning light will be on. Solution: This situation is more complicated, you need to go to the auto repair shop or 4S shop to find a professional to check and repair.

3.Serious carbon deposition in automobile engines; If the car's engine has a serious carbon deposit, the fuel cannot be burned effectively in the cylinder, and the vehicle will stall after starting. Workaround:

In this case, it is necessary to clean up the carbon deposits in the engine when it is eliminated. 4.Low pressure in the automotive fuel system:

If the pressure in the vehicle's fuel system is low, the fuel will not burn efficiently. Solution: In this case, a professional should be asked to check the fuel system of the car.

Summary. The reason for the automatic shutdown of the car after starting is the serious carbon deposition of the car engine, the failure of the car anti-theft system, the ignition switch, and the low pressure of the car fuel system. Serious carbon deposition in the automobile engine, serious carbon deposition in the automobile engine, and insufficient fuel combustion in the cylinder, will cause the vehicle to stall after starting.

In this case, the engine carbon deposits should be cleaned up in time. <>

What's going on with the automatic shutdown of the car after it starts.

Hello, Skoda Xinrui automatic transmission car, what's going on when you take a taxi and turn off.

The reason for the automatic shutdown of the car after starting is the serious carbon deposition of the car engine, the failure of the car anti-theft system, the ignition switch, and the low pressure of the car fuel system. Serious carbon deposition in the automobile engine, serious carbon deposition in the automobile engine, and insufficient combustion of fuel in the cylinder, will cause the vehicle to stall after the Kaikai operation. In this case, the engine carbon deposits should be cleaned up in time.

The repairman said that the computer does not communicate.

Dear, the reason why the automatic transmission car turns off after ignition is that the oil circuit is not smooth: the quality of the oil used in the blind travel is not enough, and too much grease will block the oil circuit, resulting in poor oil supply. The oil circuit, including the injector, throttle stool valve and tank, should be cleaned regularly. <>

The headlights, warm air, and ceiling lights are not on.

It should be a problem with the circuit.

Dear, the computer does not communicate to do an ECU upgrade. <>

Do repairmen upgrade with computers.

Dear, the headlights and air conditioner use the same insurance as the blue lead, there is no problem with the electric check ignition and repentance. Ceiling light: 1

The bulb is damaged, it is recommended to replace it with a new one, 2The fuse is blown out and disassembled, it is recommended to replace it with a new one, 3The switch is not turned on.

After turning on the switch, check if the internal dome light is on.

Kiss, it's a problem with the circuit. <>

Dear, repairmen don't do computer upgrades.

How to upgrade it.

Dear, use a specially upgraded computer to do ECU upgrades. <>

Kiss, expand: The method of automatic shutdown of the house car: clean the oil circuit, including the fuel injector, throttle, fuel tank, and keep the oil circuit unblocked.

The engine speed sensor is too dirty. Remove the sensor and wash it. The low-voltage power-off excitation chain causes the flame to stall.

At this time, you can mainly check the ignition and starter switches, as well as the fuse box. There is a lot of dirt deposited on the spool of the idle motor and the throttle seat. Carry out the clear imitation of Sun Li with dirt and dirt.

The reasons for the automatic shutdown of the car after starting are: 1. The engine has serious carbon deposits; 2. Trigger the car anti-theft system; 3. Ignition switch failure:4. Low pressure of fuel system.

1. Serious carbon deposition in the automobile engine: If the carbon deposition of the automobile engine is serious and the fuel is not effectively burned in the cylinder, the vehicle will stall after starting.

2. Trigger the car's anti-theft system: If the car's anti-theft system is triggered, the car engine can be started but cannot run normally, and the vehicle will automatically turn off after starting.

3. Ignition switch failure: If the ignition switch of the car fails, the car will automatically turn off after starting, and the vehicle fault alarm light will be on, which is more complicated, and you need to go to the car repair shop or 4S shop to find a professional person for inspection and maintenance.

4. Low pressure of automobile fuel system: If the pressure of the fuel system of the vehicle is low in the steam section, the fuel will not be effectively combusted, and the fuel system needs to be checked.

What to do if your car turns off?

1. First of all, it is necessary to determine the reason for turning off the ignition.

If the automatic transmission car stalls, it is generally caused by the use of inferior fuel, in this case, the general operation is as follows:

Hold the steering wheel with your left hand to stabilize the direction, press the brake with your right foot to reduce the speed as much as possible, and then quickly turn the AT gear to N gear, then turn the key back one notch, and then re-ignite, and then return the AT gear to D gear for normal driving.

2. Secondly, if the car with manual transmission has stalled, under the premise of quickly improving their driving skills, they must first judge whether the oil circuit is smooth, often due to this simple reason, the result is a waste of time.

Completely dredge the oil circuit, including the fuel injection cavity slip adjustment, throttle and fuel tank, etc., it may be that the quality of the engine oil you add has not passed, and there is too much glue, which blocks the oil circuit.

At the same time, the possible cause of stalling is too much dirt in the valves. When the engine is running, a lot of dust accumulates at the valve core and throttle seat of the motor, and when too much dust accumulates, the engine will have too low idle speed, poor idle stability, and finally cause idle stalling.

At this time, it is only necessary to wash the idle motor, and at the same time, the use of high-quality fuel that meets the standard is also the key to solving the problem of car stalling and avoiding excessive carbon deposition in the cylinder.
