Pressure relief performance of oil pump

In general, there are eight manifestations and solutions to the pressure relief fault of gasoline pump:

1. When the vehicle is started, there are problems that the vehicle can't catch fire and it is difficult to start.

Solution: Replace the oil pump.

2. The engine fault light of the vehicle instrument cluster is always on.

Solution: Replace the oil pump.

3. When the vehicle is driving, under the back seat, the gasoline pump makes a "buzzing" sound.

Solution: Replace the oil pump.

4. If the vehicle can't accelerate, especially when it accelerates rapidly, there will be a sense of frustration.

Solution: Replace the oil pump.

5. Engine jitter.

Solution: Replace the oil pump.

6. The hand pump reduces the oil supply (the hand pump is a machine that pumps the fuel in the fuel tank into the oil circuit).

Solution: Replace the oil pump.

7. Negative pressure appears in the fuel tank.

Solution: Replace the oil pump.

As the most basic component in the fuel supply system of the engine, the fuel pump is responsible for pumping the fuel out of the fuel tank during the operation of the engine, and continuously delivering it to the engine through the oil supply pipeline at a certain pressure, and then pressurizing it by the high-pressure oil pump for the second time, so as to provide a certain amount of fuel for each cylinder according to the working sequence of the engine.
