What are the aftereffects after replacing the fuel pump?

[Adeline]

After replacing the fuel pump, the main aftereffect is reduced power. Replacing the car's fuel pump can affect the vehicle's performance, leading to a certain degree of power loss. Precursors of a failing fuel pump include: the engine struggling to accelerate; difficulty starting the vehicle, requiring multiple ignition attempts; unstable or shaky engine operation; unusual noises, such as a humming sound while driving; a jerking sensation during sudden acceleration; and abnormal engine vibrations. Causes of fuel pump damage include: insufficient fuel in the tank, as the fuel pump relies on the fuel passing through it for cooling—without adequate cooling and lubrication, the fuel pump can be damaged; long-term neglect of cleaning or replacing the fuel filter, leading to severe blockage in the fuel supply system, forcing the fuel pump to work harder and increasing the risk of damage under prolonged high-load conditions; and poor-quality gasoline containing impurities that enter the fuel pump's internal bearings, accelerating wear and leading to damage.
