What are the reasons why a BYD car has power but cannot start?

[MacHarmony]

BYD car has power but cannot start for the following reasons: Fuel flow obstruction: No oil pressure in the engine fuel supply pipe. This situation mostly occurs on particularly cold mornings and is caused by long-term dirt in the fuel pipeline. When the temperature is extremely low, water and debris mix, blocking the fuel pipeline, resulting in failure to start. Poor working condition of the ignition system: On particularly cold days, due to the low intake air temperature, the fuel does not atomize well in the cylinder. If combined with insufficient ignition energy, the result is a flooded cylinder phenomenon, where excessive fuel accumulates in the cylinder, exceeding the ignition limit concentration and preventing the car from starting. Blown fuse in the starting system: The car fuse is a type of current fuse. When the current exceeds the rated current power of the fuse, it often blows, which can cause many of the vehicle's electronic devices to malfunction and prevent the vehicle from starting normally.
