What is the solution for the buzzing sound of the fuel pump?

[DeAshlyn]

The solutions for the buzzing sound of the fuel pump are: 1. Replace the fuel filter; 2. Replace the fuel pump. Symptoms of a faulty fuel pump include: 1. Weak acceleration, with jerking during sudden acceleration; 2. Difficulty starting, requiring prolonged ignition; 3. Engine warning light turns on; 4. Abnormal noises while 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 and clogging of the fuel pump suction filter; 2. Failure to replace the fuel filter, which intercepts foreign particles and impurities, at regular intervals; 3. Delayed refueling, accelerating 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, thereby lubricating the main moving components of the engine and ensuring the oil is filtered.
