Can Unstable Fuel Pump Pressure Be Repaired?

[DeSawyer]

Unstable fuel pump pressure can be repaired. Symptoms of unstable fuel pump pressure: When the vehicle is moving, abnormal "buzzing" noises come from the fuel pump under the rear seat; the vehicle lacks power during acceleration, especially experiencing jerking during sudden acceleration; difficulty starting the vehicle, with problems like failure to ignite; the engine warning light on the vehicle's instrument cluster remains constantly lit. Normal values for fuel pump pressure: When the ignition is turned on without starting the engine, the fuel pressure should be around 0.3MPa; when the engine is started and idling, the fuel pump pressure should be around 0.25MPa.
