What are the symptoms of a faulty fuel pump in Wuling Rongguang?

[McMiguel]

Automobile fuel pump failure symptoms:1. Complete failure: When the fuel pump is completely damaged, it cannot pump any fuel at all, causing the fuel supply system to collapse and the vehicle to be unable to start.2. Partial failure: If the fuel pump check valve is damaged, it will result in no residual pressure, and the fuel pressure will not reach the specified value, greatly reducing the atomization effect, making it difficult to start the engine and requiring multiple ignition attempts over a long period. If the centrifugal pump impeller is worn, it will lead to reduced fuel supply pressure, absence of the fuel pump operation sound, insufficient fuel supply, weak acceleration, and abnormal noises such as buzzing sounds while driving.3. Mechanical failures such as rotor jamming: The working current of the fuel pump increases, causing damage to the relay or fuse.4. Engine malfunction light on: The engine shakes abnormally.
