The engine didn't respond when Le Feng struck a light. What happened?

Because sometimes even if the headlights and other electrical appliances have electricity, the engine can't start, because the current required for the engine to start is very large. If the battery is dead, it can drive the electrical appliances in the car, but it may not drive the starter. The phenomenon you are talking about may be the performance of the battery losing power. It may be caused by excessive carbon deposition in throttle, idle motor, air intake and combustion chamber. Due to too much carbon and dirt in the air inlet, the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle intake air volume, resulting in the mixture being too rich or too thin and the engine unable to start. It is also possible that the fuel constant pressure performance of the electronic control system is poor and the fuel pressure is low, which leads to poor atomization of fuel injection at low temperature and difficult starting. It is suggested that you can turn the key to the fully open position of the instrument light when starting, and wait for a while, or the engine can complete the self-test procedure, which is also beneficial to the whole engine and other electrical equipment. At this time, you can hear the noise of the oil pump. When the sound ends, close the key door, then repeat the above operation for two or three times, and then start it again. The increase of fuel consumption is also related to the poor atomization of mixed gas caused by low temperature. What is the reason why Chevrolet Sail will automatically refuel?
