Pump Fuel – MAZDA (AJ5113350)

Pump Fuel delivers fuel from the tank to the rail at the pressure the calibration expects. Output falls off gradually with wear, so the first symptom is usually a lean code or a misfire under load rather than a no-start.

Replace the Pump Fuel when a lean code appears under load, when the engine cranks without starting, or when rail pressure bleeds down overnight. Change the fuel filter with the pump, because the debris that killed one shortens the life of the other.
