I'm Kerry Yousheng. Why can't I start the car when it's cold?

There are many reasons why the cold car doesn't start. Please refer to the following points for inspection: 1, there is no strong smell of gasoline in the exhaust pipe, indicating that the cylinder is short of oil, which may be a problem with the fuel pump, oil circuit or oil pump circuit. 2. After flameout, the water temperature is too high for thermal protection. It is recommended to check the electronic fan and clean up the fault of the water tank or water temperature sensor. 3. The throttle is too dirty, that is, there is too much carbon and dirt on the throttle and the surrounding air intake.
