How can you tell if the oil pump of the car is broken? What is the phenomenon?

The common causes of fuel pump damage are as follows:

1. The fuel level warning light in the instrument with insufficient oil in the oil tank is on, because the liquid level is too low, the fuel pump motor cannot be cooled and lubricated sufficiently, which will cause the motor to overheat or even not work. In the long run, the damage of the gasoline pump will be accelerated.

2. The quality of gasoline is too poor. There are impurities or foreign matters in the gasoline. If the gasoline pump is too dirty, these impurities enter the internal bearing of the gasoline pump, which will accelerate the wear of the bearing and cause the damage of the gasoline pump.

3. the gasoline filter is not replaced for a long time, the gasoline filter is blocked, and the internal part of the gasoline pump is under high load for a long time, causing damage to the gasoline pump.
