What if the car doesn't catch fire? The dashboard flashed, but it didn't catch fire. Click.

The most common reason why the car can't catch fire is that the battery of the car is dead, which leads to the starter can't drive the engine to reach the starting speed, and the magnetic bag and the starting relay are repeatedly attracted to produce clicking sound. To judge whether the car battery is dead, you can turn on the headlights or interior lights before confirming the start, and observe whether there is any light and shade change during the start. If it is obviously black, it means that the battery voltage is insufficient. In addition to the dead battery of common cars, there are other reasons that cause the dashboard of the car to flicker, fail to catch fire and make abnormal noise: 1, too much carbon deposit in the intake pipe, throttle valve and idle motor, which makes the mixture of the engine fail to meet the required air-fuel ratio; 2. The fuel system is short of oil supply, and the air-fuel ratio of the mixture required by the engine cannot be reached; 3. The starting motor or related circuit fails, resulting in that the electromagnetic coil can't maintain the pull-in state and can't provide the torque needed for starting; 4. The engine can't be started because of the ignition system failure. If the key door is always in the start position, the start relay will be pulled in repeatedly and there will be a click. Good car habits of car owners can prolong the service life of car batteries, such as avoiding parking in open-air parking lots for a long time; Turn off the electrical equipment on the car after the flameout; If you don't run at high speed for a long time, start the car to charge the battery every once in a while.
