What happened when Subaru xv didn't start?

The first reason is battery damage. If this is the reason, it is difficult for ordinary car owners to find out for themselves, and they all need to be sent to a repair shop for testing through professional computer equipment. In addition, it is also possible that the battery is dead. If you often drive at a low speed in the urban area, the headlights, air conditioners, stereos and other equipment are always on, and the battery consumption is relatively large, which may lead to insufficient power. I suggest you run at high speed to fully charge the battery.

The second reason is that the fuel-air mixture ratio of vehicles is abnormal, which is also the most common and typical reason. In this case, the engine is usually normal, but it just won't start. This phenomenon usually occurs because the throttle valve, intake valve or idle motor are too dirty. If the valve is too dirty, gasoline will be sprayed on the back of the valve and absorbed by carbon deposits, so you can't touch the car. General cleaning can solve the problem.

The third reason may be that the supply voltage of the ignition system is unstable. In winter, the automobile has great starting resistance, including insufficient battery power, which leads to insufficient voltage of the whole ignition system. In addition, many car owners report that if the fuel supply is not continued, the car will turn off immediately. This is because the motor and nozzle are too dirty, so you can increase the throttle slightly, but if it doesn't work, you have to send it to the repair shop for thorough cleaning.
