Transfer Pump (Protege 4WD)
Because of the rear drive shaft, the fuel tank is in 2 sections. A transfer pump keeps both sides of tank at equal fuel levels. An access panel is located under the rear seat. Transfer pump control unit is located under driver's seat. Disconnect the transfer pump connector at the fuel tank, and check continuity between Black/White and Yellow wires. If no continuity is present, replace transfer pump.
