These may be the reasons why the car won't start. Don't be cheated when repairing the car.

Many drivers have many years of driving experience, and they often encounter situations where their cars can't start, and most of them happen suddenly. For example, if they stop for a while and come back, the car will not catch fire. Most drivers don't know what causes the car to fail to start. When they send it to be repaired, they will replace it everywhere. As for whether they need to change drivers, they don't know. Here are some reasons why cars can't start, so that everyone can learn to find their own faults.

The battery is low.

When the battery is dead, the car won't start. This situation generally does not happen suddenly. For example, the car was still in use just now, but it won't start after stopping for a while. This situation is generally not caused by battery power failure. It is very hot in summer. Turning off the engine and blowing the air conditioner in the car can easily lead to dead batteries. So when our car doesn't catch fire, we can first check whether the battery is short of power or damaged. To detect the battery power shortage, you can buy a cigarette lighter that can display the voltage, try to start the car, and pay attention to the change of the voltage value. If the voltage is displayed above 1 1V at startup and does not drop immediately, there is a high probability that the battery will not display or drop sharply. Old drivers usually judge by the sound of the engine when starting, but it is not accurate enough.

Ignition system failure

If it's not the battery, we must rule out whether the ignition system can't start the car. The ignition system regularly supplies high-voltage electricity to the spark plug. If there is a problem or leak in the wiring connection in the ignition system, the ignition system will fail and the car will naturally be difficult to start. Pay attention to safety when checking the circuit, don't touch and disassemble it, take protective measures, and it is best to go to a professional repair shop for repair to avoid life-threatening faults such as electric shock or broken lines.

Starter failure

Another situation is that the car won't catch fire, that is, the starter is faulty. Starter faults are common, which will inevitably age after a long time of use, leading to the weakness of the starter and the difficulty of starting the car. If the starter is broken, the car won't move, so you can only let the trailer drag the car to the repair shop and let him check and repair the starter for you. After the general repair shop confirms that it is a starter, it will directly replace it with a new one, saving time and effort.

Conclusion: After knowing the reasons why the above cars can't start, when your car can't catch fire, you can try to judge what caused it first. Don't change your battery, fuse and starter when you arrive at the repair shop, which is a waste of money.
