The symptoms of a bad car fuel pump are: 1. Weak acceleration, with jerking when accelerating suddenly; 2. Difficulty starting, requiring prolonged cranking; 3. Engine warning light illuminated; 4. Unusual noises during driving; 5. Abnormal engine vibration; 6. Failure of the fuel supply system. The causes of fuel pump damage are: 1. Use of low-quality gasoline, leading to excessive impurities clogging the pump's suction filter; 2. Failure to replace the fuel filter that traps foreign particles and impurities regularly; 3. Delayed refueling, causing accelerated damage to the fuel pump. The function of the fuel pump is: to pressurize the oil from the oil pan and deliver it to the oil filter and various lubrication channels, lubricating the engine's main moving components and ensuring the oil is filtered.
