What's the reason for a car not starting or responding?

[DeNicole]

The reasons for a car not starting are as follows: 1. Improper fuel quality, lack of antifreeze, excessive carbon buildup, excluding improper human operation. 2. Starter motor failure, fuel pump supply issues, injector problems, sensor malfunctions, etc. These more complex situations require professional handling. Below are some vehicle usage precautions: 1. Fuel quality issues: During repairs, it was found that the fuel tank contained water and sludge. Using such fuel will inevitably damage the car. Always refuel at reputable gas stations, and when traveling, you can use a gauze filter over the fuel nozzle to filter out impurities. 2. Lack of antifreeze: Using water or substandard antifreeze in extremely cold winter conditions can cause the entire cooling system to freeze, potentially cracking the engine block, rendering the water pump inoperable, preventing the car from starting, and damaging other engine components. 3. Excessive carbon buildup in the vehicle can also prevent it from starting. Regular use of the car helps reduce carbon buildup.
