1. Check the battery status. Starting difficulties are mainly caused by loss or expiration of battery life. When the battery power is low, the speed is low when starting the car and only a click will be heard. When the contact is turned back on, the click will gradually turn into a click. Do not turn on continuously to avoid running out of battery.
2. Replace the appropriate engine oil. As the temperature decreases, the viscosity of the engine oil will increase, making it difficult for the oil to flow, thereby increasing engine resistance. If it is difficult to start, please check whether the engine oil used is of poor quality.
3. Replace the spark plugs in time. After several years of use, spark plugs can easily cause problems such as carbon deposits, leaks, excessive gaps, ablation, etc.., which can cause difficulties in starting the car. cold start, or even hot start of the engine, often requiring multiple ignitions. So, if you have traveled a certain number of kilometers or if you feel that the vehicle is having difficulty starting, running weakly, vibrating, increasing fuel consumption or stalling for no apparent reason, please check the condition of the spark plug and the replace. on time.
Detailed information:
1. The vehicle is more difficult to start than usual, it has to be turned on more than once, and it appears that the starting power is insufficient. .
2. When the vehicle is idling, the headlights quickly change from bright to dark, indicating that the battery power is insufficient and needs to be replaced.
3. When the dBattery life is approaching, it will affect the work of the generator. Usually, the generator will make an abnormal noise when starting the vehicle, usually a slight grinding sound, but it may disappear in three to two seconds or less. As the power decreases, the frequency and duration of this sound will gradually increase.
4. The car usually drives normally, but sometimes the entire car will lose power when restarting after parking. This is because when the battery life comes to an end, the starting current is not enough, resulting in increased oxides in the battery connectors, putting the entire vehicle without power.

The first is to hear the sound of the starter, but the engine cannot start. The other is that after turning the key, there is no sound.
Causes:
1. Battery Loss
When the car battery loses power, the car will not be able to start, which will cause the car battery to fail. Power loss reasons, such as battery lack of water, battery is defective, and air conditioner is used for too long, etc., which may cause the car battery to lose power. When the car won't start, you should first check whether there is a problem with the car battery and what the problem is, then send it to a 4S workshop for repair.
2. The temperature is too low
The weather is cold in winterWhen it is cold, cars often do not start. Indeed, in the vicinityLow temperature rumbles, the viscosity and speed of the car's engine oil decrease, resulting in a decrease in battery ignition energy and reduced molecular activity. Therefore, no flammable gases can form, making it difficult to start the car. .
If this happens, don't panic. It's not that the car has a malfunction, it's a normal phenomenon. You can try pressing the clutch first, then turning on the ignition. Getting started might be easier. the car.
3. Carbon Deposits in Automobiles
Carbon deposits in automobile engines can cause many problems. The most common problem is that the car cannot start. Carbon deposits in the engine can have many causes, such as high humidity in gasoline, poor quality fuel type, poor sealing of engine seats.valve, etc. So, if the car does not start well, you might as well check whether the car engine has a lot of carbon deposits. If so, clean it in time.
