The car suddenly stalled while driving, but the power was uninterrupted

There are generally three reasons why a car suddenly stalls while driving.

One is circuit failure. This possibility is that the power is cut off due to low voltage during driving. At this time, you can mainly check the ignition and starter switches, as well as the fuse box.

A short circuit in a low-voltage line causes a flameout, in which case it is an intermittent flameout. Check your low-voltage lines.

One is device failure. This problem is generally the ignition coil, capacitive electric, electronic ignition module. It starts at the beginning, turns off after a while, and then starts again and turns off again.

There is also the failure of the oil circuit. The gasoline pump was damaged, the oil line was ruptured, the carburetor inlet was clogged, and the fuel tank ran out of oil. But in this case the car can be restarted, but it is difficult.

Ignition system, engine overheating and detonation system will turn off if there is a problem, you check it, it is the best problem.

How did you solve your problem, and I have that problem too.

The sudden engine stalling is mainly due to the engine fuel injection failure, air intake failure, complete damage to the engine battery or loose positive and negative poles of the battery.

Engine fuel injection system failure.

During the normal driving of the vehicle, if the engine suddenly has a fuel injection failure, the engine fuel injector is blocked, or the engine fuel pump is blocked, the engine can not supply fuel normally, and the vehicle is in the process of driving, if the N gear is sliding, the engine stalls more commonly.

However, if it is driven in D or M gear, the engine is unlikely to stall, because in this case, the engine relies on the inertia of the vehicle to run backwards, and the engine does not need fuel auxiliary work.

Engine intake system failure.

For the engine intake system, if the vehicle is driving, when idling in N gear, the engine takes in air through the throttle bypass valve, but if the bypass valve is closed, the engine air intake is zero, which naturally leads to no gas supply in the engine cylinder, and the engine fuel injection is also reduced accordingly, and there will be no fuel combustion inside the engine at this time, which naturally causes the engine to stall.

In addition, if the intake flow sensor and intake pressure sensor of the vehicle are abnormal, it will also cause the engine to inject abnormal fuel and then cause the engine to stall.

Failure of the vehicle's power supply system.

If the engine suddenly stalls, it is also possible that there is an abnormality in the vehicle's power supply system. After all, if the vehicle battery is completely damaged, there is no power at all, or the positive and negative poles of the battery are not firmly connected, and there are traces of loosening, at this time, the engine cannot inject fuel normally through the fuel injector, and the engine fuel injector is likely to fail to open normally, resulting in abnormal engine work and stalling.

The reasons why a car suddenly stalls while driving are:

1. Circuit failure: In the process of driving, due to low-voltage power failure, check the ignition and starter switches and fuse boxes;

2. Flameout caused by short circuit of low-voltage line: In this case, it is intermittent flame-out, check the low-voltage line, etc.

Hello I want to consult, my car is 21 business class 652T premium version on the road, that is, yesterday afternoon in the right turn waiting for the car is, suddenly turned off, I look at how it became N gear, what's going on.

Hello, there are several common possibilities for the car to suddenly turn off during driving, the more common thing to encounter is that the fuel pump is broken, and the generator is damaged so that the car does not generate electricity, the power is exhausted, and the module cannot work automatically turned off, and there are some engine control systems, such as oxygen sensors, intake manifold absolute pressure sensors, air flow meters, so the specific needs to be eliminated step by step, and the engine has no relevant fault codes.

There was no alarm prompt for the question, I tried it last night, and I opened it this morning and it was fine.

Just bought it for more than a month.

Do you use N gear when waiting for a red light? Or D gear to hit the brakes.

Answer: If it happens occasionally, for example, there is a problem in the module, the fault code will be stored, although there is no problem now, there will be a historical fault code detected by the diagnostic computer, so you can use the computer to check it first.

Generally speaking, the brakes are stepped on in D gear, but depending on the traffic light time, you can draw neutral, after all, it is too tiring to step on it all the time, but pay attention to walking in neutral gear.

Ask whether it is better to turn off the automatic start and stop or not.

The answer to my suggestion is to turn it off, because I have encountered the owner of the car when it rained heavily and did not turn off this function, resulting in the car starting 2 times, and the engine was damaged due to water ingress, but this is more troublesome, and it has to be turned off manually every time.

First of all, don't panic, quickly observe the surrounding traffic conditions, if the surrounding traffic conditions and conditions allow, you can try to restart the engine without stopping, because the automatic transmission car has a neutral safety switch, the vehicle can only start in P gear and N gear, because the vehicle is still coasting by inertia, so you can not push the gear lever directly to P gear, but you can change into N gear first; The method of restarting the engine is: quickly push the gear lever to neutral, generally do not need to step on the brake to shift the gear lever from D gear to N gear, turn the ignition switch to the starting position, restart, and then quickly pull the gear lever to D gear after success, you can drive normally; If the engine still fails to start after many attempts, it means that the fault is more serious, then you should pull over, turn signal first, and stop slowly while observing the traffic conditions; The ignition switch of some cars has the function of preventing secondary starting, and it must be turned back to the closed position before it can be restarted, but you must be careful not to let the steering wheel lock; In addition, when the engine is turned off, the brakes and steering assist also fail, and more force is required to control the vehicle; If you are a novice, it is best to pull over to the side of the road first and call for help or rescue, remembering that at no time a vehicle equipped with an automatic transmission can be started with a reverse tow.

Hello 1The car runs out of fuel tank;

electrical problems; Faulty ignition coils, resulting in no high voltage for all spark plugs;

The gasoline pump is damaged and cannot pump oil;

Excessive carbon deposits at the throttle;

engine computer failure;

The timing belt breaks. The solution to the sudden shutdown of the car while driving: When it is found that the engine is turned off, according to the road conditions at the time, if there is no emergency, you can slowly step on the brakes to prevent rear-end collisions, after the speed of the car is reduced, slowly hit the direction, drive to the roadside lane, park the car on the side of the road, turn on the four flashing lights, place the tripod, and call ** rescue trailer.

Circuit failure, this may be due to low-voltage power failure during driving, flameout, at this time you can mainly check the ignition and starter switch and fuse box;

Electrical device failure, this problem is generally the ignition coil, capacitance, electronic ignition module, can be started at the beginning, after a while will be extinguished, and then it can be started again, and then extinguished;

Oil circuit failure, gasoline pump damage, oil pipe rupture, vaporizer inlet blocked, fuel tank out of oil, in this case the car can be restarted, but it is difficult;

Sensor failure, throttle position sensor, intake flow sensor, intake pressure sensor, crankshaft position sensor, camshaft position sensor failure, etc., if the sensor is faulty.

Sudden flameout? The automatic transmission is a vehicle failure, and the manual transmission may be that the gear is too high, and the engine speed is lower than idle.

Solution: You can step on the brakes and turn on the double flash. If it's a vacuum-assisted brake, there is only one chance to step on it, so don't waste it.

In general, there is no oil in this situation. Or if there is no power, don't panic when this happens, and check it after slowly parking the car.

There should be no problem, there are more electronic products, there are more things, it is good to be able to open, I want to start one, but unfortunately there is no 100 million on hand Now it is Magotan to open, and I can also encounter electronic problems once a year, all fine, and I didn't go to the Si'er store. Lock the car and wait for a while before opening, everything is OK

You can go to the repair shop and check it out.

Engine failure, either no gas, that's it.

Reasons for the sudden stalling of the car while driving:

1. Circuit fault;

2. Flameout caused by short circuit of low-voltage line: intermittent flameout; 3. Device failure: it can start at first, turn off after a while, and then start again, and then turn off again;

4. Oil circuit failure; The gasoline pump was damaged, the oil line was ruptured, the carburetor inlet was clogged, and the fuel tank ran out of oil.

5. There is a problem with the ignition system and the explosion-proof system for engine overheating.

When it is found that after the ignition is turned off, according to the road conditions at the time, if there is no emergency, you can slowly step on the brakes to prevent the tail light, after the speed is reduced, slowly play the direction, drive to the roadside lane, pay attention, the brake should be stepped on all the time, the power from small to large, do not step on it and then loosen, and then go to the pedal, which will lead to the only remaining vacuum is also consumed, and then step on it can not be stepped on, park the car on the side of the road, turn on the four flashing lights, place the tripod, and hit the ** rescue trailer.

The line from the battery to the fuse box should be inspected for damage or burning. Check the main circuit or main fuse of the fuse, and check whether the electrical appliances are burned or damaged. Check if the main switch of the key is damaged.

There should be a problem with the battery, or the circuit is short-circuited.

Hello, the automatic transmission car suddenly turned off while driving, and the whole car was powered off.

It's definitely a matter of the total power :

1. You first check whether the battery clip is firm.

2. Check whether the live wire and the iron wire are firmly fixed with the car body.

3. And check whether the main line is short-circuited or broken, that is, check whether there is a place in the main line that seems to be connected.

4. If necessary, try it with a new line.

5. If the fault is still there, try to change the level to see if the electrodes inside the battery are not welded well.

6. If your model has a total power relay, first check whether the total power relay is working properly, and try to change it if necessary.

7. Engineers are in accordance with conventional inspection methods, and some faults are exceptions, and repairing a lifetime car may not be able to meet once.

8. The outer skin of the wire is very good, but the inside seems to be broken, sometimes the work is still very normal, the whole car is powered off, and the computer is too late to record the fault code, so the detector is not used.

The reason for the sudden flameout.

1. Engine stalling is one of the common reasons:

a. Engine stalling is one of the common reasons for land wind stalling, which is manifested as the unstable operation of the engine when idling, and the exhaust pipe makes a purring and purring sound.

Solution: The main cause of the fault of the car stalling in the idle state is due to too much dust in the air, which can be solved by cleaning the idle motor.

b. The engine is shaking, followed by stalling, and the second start will be normal!

Solution: Replace the gasoline filter, clean the throttle, and check the spark plug combustion. Or you can turn the ignition switch to the power-on self-test state first, stay for dozens of seconds, let the oil, oil pump or something run for a while, and then ignite.

2. Troubleshooting method for automatic transmission car shutdown:

Pay attention to the place: for the phenomenon of automatic transmission car stalling, it is mainly caused by the use of inferior fuel ridge.

Practical operation: Hold the steering wheel with your left hand to stabilize the direction because there is no power assist, so you must stabilize it hard, press the brake with your right foot to reduce the speed as much as possible, and then quickly hit the AT gear to N gear, then take the key back one notch, and then re-ignite, and then restore the AT gear to D gear for normal driving.

3. Troubleshooting method for manual transmission car ignition:

Solution: Clean the oil circuit thoroughly, including fuel injectors, throttle valves, fuel tanks, etc. It may be that the quality of the oil you add is not up to standard, there is too much grease, the oil path is blocked, and the oil attack is not smooth.

4. Long-term parking is not used

Land breeze flameout is closely related to long-term parking and non-use, because long-term parking can lead to lubrication or electrical problems.

Solution: A thorough maintenance should be done before re-using Qingpei, replacing the oil, filter, etc., and checking the fuel and circuit as appropriate.

Summary. Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Suddenly turn off the engine while driving, and the whole car loses power?

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, I hope this time can be helpful to you. In this case, it is recommended to check the working condition of the battery, or it may be that the battery pile head is connected or the generator fails to cause the wild rush to start. The inspection is that the battery pile head, the grounding wire or the generator does not generate electricity, or the motor belt is broken or falling off.

After a minute, it was restored and it started normally again.

In this case, it is a problem with the module, ignition switch or fuse box, and if possible, you can use the diagnostic computer to read the fault code.
