What are the reasons why a car suddenly cannot start?

Reasons why a car suddenly cannot start: 1. Dead battery: Sometimes you may find that the car cannot start normally in the morning, which is likely because the trunk was not completely closed, causing the trunk light to stay on and drain the battery; 2. Spark plug failure: Spark plugs themselves are prone to damage, and a short circuit in the high-voltage line can prevent the spark plug from igniting. Another reason is that poor-quality spark plugs can also cause the car to fail to start normally; 3. Starting circuit malfunction: When starting, there is only a slight click sound and no further response, which is caused by a stuck starting relay. To identify the cause of the fault, first check the battery to determine whether the engine's failure to start is due to insufficient battery power. To inspect the starting system, first examine the circuits in the engine starting system. Generally, the starting system's circuits include the battery, the starter motor, and the cables connecting these components.
Oh, I remember one time when my car suddenly wouldn't start, and I was running around in a panic. That morning, as I was getting ready for work, I inserted the key and turned it, but the engine didn't respond at all—not even a sound. I guessed it might be a battery issue, possibly low charge, especially since I hadn't changed it in five years. Later, I had to call a friend to jump-start it to get it going. Don't ignore starter failure—if you hear a clicking sound, it's time to check it. Fuel system problems could also be the culprit, like an empty tank or a damaged fuel pump. Dirty ignition coils or spark plugs can affect ignition too. It's a good idea to keep a jump-starter handy for emergencies, and preheating the car in cold winters helps. Regular maintenance is especially important to avoid such embarrassing situations. Remember to check if the battery terminals are loose—a simple thing can save you a lot of trouble.
