Fuel Pump Resistance

CAUTION: Fuel pump and fuel sending unit are separate components. Fuel pump is accessible through vehicle interior, but fuel pump connector is accessible through luggage compartment (near fuel sending unit).

Remove trim cover from behind rear seat in luggage compartment. Disconnect 2-pin fuel pump connector (NOT the sending unit connector). Measure resistance between female terminals of fuel pump connector. Replace fuel pump if resistance is not 0.2-3.0 ohms at 68°F (20°C).
