First point, test if the battery has enough power to start. Press the horn to see if the volume changes. Turn on the high beams to see if they reach a reasonable brightness. Second, it has nothing to do with starting the car. the generator and mainly depends on the generator. Starter, when you turn on the ignition switch, does the starter speed reach the cranking speed? If the ignition switch is on and the starter makes a “click” sound, that means the magnetic switch? on the starter is damaged and must be replaced. If the ignition switch (i.e. door key) is turned to the start position and the starter turns very slowly, this means the battery is discharged and needs to be replaced. be loaded. After starting the car, use a multimeter to measure the generator output current to see if it meets the charging standard. HabiCurrently, 1.5V more than the battery is considered good, finally check if the battery has reached its level. lifespan and must be replaced.
What is the reason why the car stops turning on while driving and cannot restart?
1. Reasons why the car cannot turn on without electricity:
< p >1. Human operation reasons: the battery is discharged, the fuel tank is out of fuel, and the gear is incorrect(1) Lack of fuel. Once we went out to save a car. The fuel gauge indicated that it was below the red line, so naturally it couldn't start the fire.
(2) The battery is discharged. This may be due to loss of power or expiry of battery life for reasons such as leaving the headlights off for a long period of time. It is generally recommended toe replace the battery every two years. Additionally, the installation of xenon headlights, high-power audio, DVD, etc. is possible. are also the cause of vehicle circuit failures. It's easy to check if the vehicle is off, just press the horn to find out.
(3) The equipment is incorrect. When starting a car with an automatic transmission, the gear must be placed in P or N. If it is placed in R or D, it will not start. There are also manual transmission cars that will not start unless the clutch is depressed.
2. Reasons for using vehicle: improper oil, no antifreeze, excessive carbon deposits
(1) Oil problems. When we were repairing a car, we found water and mud in the fuel tank after we took it apart. With such oil, it would be impossible for the car to break down. Therefore, car owners are remindedto go to regular gas stations to refuel. When you go out, you can take a gauze bag to the refueling nozzle to filter impurities.
(2) No antifreeze added. Some car owners add water or poor quality antifreeze to their car. As a result, when the winter is extremely cold, the entire waterway is frozen and the engine is cracked, causing the car's water pump to fail to work and catch fire. and damage other parts of the engine.
(3) Excessive carbon deposits in the vehicle will also prevent the vehicle from igniting. The solution is to reduce carbon deposits by frequently driving at high speeds. Additionally, there is a little trick if you are unable to initiate contact. Before driving the car, turn the key to the ON switch, then turn it back on, then turn the STRAT switch to turn on. Temperaturee water and appropriate air intake, and the ignition will be relatively smooth.
2. Other reasons:
1. When the battery is at low temperature, due to the increase in electrolyte viscosity, the penetration capacity decreases, the resistance increases, and the output power is reduced, causing the starter to lag. The engine has difficulty reaching minimum starting speed, which affects engine starting. If the car takes a taxi, the engine does not turn over or runs very slowly when it is on fire, it is very likely that the battery is dead or malfunctioning.
2. At this point, check the spark plug to see if it is aging or has significant carbon deposits, and replace it with a new one if necessary.
3. When lighting, lightly press the accelerator to allow the gasoline to flow more quickly, making ignition easier.
4. If it is a diesel vehicle, the problemnon-ignition is more serious in winter. The main solution is to replace the diesel in advance, especially for old diesel vehicles when the ambient temperature is close. 0 degrees, it is recommended Replace with minus 10 diesel.
3. How to start the car in winter:
1. After starting the engine in winter, turn on the lights, radio and other electrical equipment. Before parking, turn off these energy-consuming electrical appliances and then turn off the engine.
2. When the car cannot start for the first time, do not start it a second or third time... This will only accelerate the consumption of electric power. Therefore, when it fails to start for the first time, it is better to wait 30 seconds before making a second attempt to start. Also, do not rush to drive at high speed after starting the car. Give the vehicle some warm-up time, so the vehicle is less likely to wear out and can improve fuel economy. Generally, wait for the water temperature to rise before refueling and driving fast.
Hello car owner, I am happy to answer your questions. There are many reasons for this factor, I will give you some examples
1. does not generate electricity, so the battery power consumption cannot operate the oil pump.
2. The oil level sensor is damaged, indicating there is oil but not the fuel tank.< /p>
3. The oil pump relay and insurance, or the oil pump itself, are damaged, leading to oil failure.
4. The spark plug and ignition coil are damaged, or driving stalling is caused by heavy carbon deposits
5. The engine timing belt is damaged, or there is a problemmechanical theme. failure inside the engine.
I hope my answer will be useful to you. If you still have questions, you can continue to ask me. I wish you a happy life and a successful career. If you have any questions about your car, ask them. the master of the car. Professional technicians from 4S stores can solve the problem within 10 minutes.
