Diagnosis

The first step in diagnosing fuel pump flow problems is to check the fuel pressure.

Repair

If a problem with the fuel pump is suspected, it will need to be replaced. Before replacing the fuel pump, the vehicle’s fuel tank will need to be drained of gasoline to prevent the risk of fire.

When replacing the fuel pump, it’s important to use a pump that is recommended by the vehicle manufacturer. After the new fuel pump has been installed, the fuel pressure should be checked again to ensure that it falls within the manufacturer’s specifications.

If the fuel pressure is still low, the fuel pressure regulator may need to be replaced.
