Signs that the fuel pump is not working properly

The fuel pump is responsible for supplying the required amount and pressure to the engine injectors.

Vehicles work thanks to the work of many mechanical and electrical components, and each of them has a high degree of importance. This is why preventive maintenance work must be carried out on an ongoing basis to ensure that everything is in good condition.

Gasoline is one of the most important fluids in a car.. Without this fluid, the car simply does not work, and in order for fuel to get everywhere you need to have fuel pump works correctly.

What does a fuel pump do?

The function of the fuel pump is to supply the necessary pressure to the engine injectors.

La fuel pump stock fuel to the injection system or to the carburetor, depending on your vehicle. Through these mechanisms, the liquid reaches the combustion chamber and allows engine works properly

The fuel pressure that the fuel pump raises must be constant, as is the amount that is supplied.

How to understand that the fuel pump is faulty?

Faults indicating fuel pump failure:

– The car does not start or starts intermittently

If the fuel pump fails, the car will not start. Since the pressure does not reach the injectors, the fuel does not reach the cylinders, so the engine lacks the necessary means to start.

– Lack of power

A faulty fuel pump will result in a loss of power when the vehicle is running hard or the engine needs to be boosted. This is caused by low pressure or a small amount of fuel ejected by the pump.

- Jerks during acceleration

If the fuel pre-filter is clogged, the pump will not work well, as it will not be able to pump gasoline out of the tank at a constant and sufficient pressure, this will cause the car to jerk during acceleration.

acceleration delay

- If during acceleration the car reacts as if it is about to stall, then it reacts and accelerates, it's time to check the fuel pump.
