Fault performance of gasoline pump

1. The gasoline pump is broken, usually it is unable to accelerate, and there is a phenomenon of car damage when refueling. 2. It is difficult to start when starting, and it needs a long time to turn the key. 3. Abnormal noise. There is a buzzing noise when driving. 4. The engine fault light is on. 5. Abnormal phenomenon of engine shaking.
Fault of gasoline pump:
The check valve of the gasoline pump is damaged: there is no residual pressure, which makes it difficult to start.
Centrifugal pump impeller wear: oil supply pressure decreases and acceleration is weak.
Carbon brush wear: the gasoline pump stops running and cannot be started. In this case, you can knock the bottom of the oil tank and the oil pump can still operate.
Mechanical faults such as rotor sticking: the working current of the oil pump rises, causing damage to the relay or fuse
The gasoline pump is an important fuel supply system on the vehicle. If it does not work during driving, it will directly cause the vehicle to be unable to run, work poorly, and cause the vehicle to accelerate and gasp. If there is a fault, there is no warning, and it cannot be started. It is also inconvenient to deal with it. Therefore, it is very important to find and judge faults and solve them in time.
