What are the symptoms of a faulty fuel pump in a car?

[DiSawyer]

When a car's fuel pump is damaged, the engine typically exhibits symptoms such as poor acceleration and abnormal noises. Below are detailed descriptions of car conditions when the fuel pump is faulty: 1. Poor Acceleration: There is a jerking sensation during rapid acceleration; the car is difficult to start, requiring prolonged turning of the key. 2. Abnormal Engine Noises: Unusual noises occur while driving; the engine shakes, and the engine warning light comes on. 3. Fueling Precautions: When refueling the car, do not wait until the fuel warning light comes on to add fuel, as this will shorten the fuel pump's lifespan. 4. The fuel pump is a critical component of the car's fuel supply system: If the fuel pump fails while driving, it can directly cause the vehicle to become inoperable, perform poorly, and exhibit symptoms like labored acceleration.
