When the vehicle suddenly stops running, it cannot be started.

The reason why the vehicle stopped suddenly is: 1. Circuit failure: During driving, due to low-voltage power failure and flameout, you can mainly check the ignition and starter switch and fuse box; 2. The short circuit of the low voltage line leads to flameout: in this case, the flameout is intermittent, and the low voltage line can be checked; 3. Device failure: including ignition coil, capacitor and electronic ignition module; 4. Oil circuit failure: the gasoline pump is damaged, the oil pipe is broken, the oil inlet of the carburetor is blocked, and the oil tank is out of oil; 5. Ignition system failure: If there is a problem with the engine overheating explosion system, it will turn off. The treatment of sudden engine flameout during driving is as follows: 1. When the car suddenly turns off during driving, turn on the danger warning light in time to remind the passing cars. In this process, we must control the steering wheel of the car and try our best to stabilize the car, because once the engine of the car is turned off, it will lose the steering power and the steering wheel will be heavy, which requires the owner to control the direction; 2. Stop properly. After the engine is turned off, the hydraulic pump of the brake will stop working, and the brake may not be able to step on it. Therefore, this foot brake is very important. If the operation is not good, the safety hazard is very great. Use the gear to slow down and step on the brakes when the right time comes. After parking, observe the situation outside the car, open the door and put warning signs as required.
