What's the reason when a Buick car won't start?
1 Answers
There are several reasons why a Buick car may fail to start: Battery depletion: Vehicle failure to start due to a depleted battery is generally manifested by the starter not working or showing significantly insufficient rotation speed during ignition. Fuel flow obstruction: This typically presents as a lack of oil pressure in the engine's fuel supply line. At extremely low temperatures, water mixed with debris can block the fuel line, preventing the car from starting. Poor ignition system performance: In cold weather, due to low intake air temperature, fuel atomization in the cylinder is poor. If combined with insufficient ignition energy, this can lead to cylinder flooding—where excessive fuel accumulates in the cylinder, exceeding the ignition limit concentration and making the car unable to start.
