Ford Explorer Mercury Mountaineer Fuel Pump Module Assembly 2002-2003 4.0L V6 4.6L V8 Replacement E2334M BDFHYK

Extended cranking, low measured fuel pressure, hesitation under load, intermittent stalling, or an inaccurate fuel gauge can indicate an in-tank module fault after the fuse, relay, power supply, ground, wiring, and fuel lines have been tested. This E2334M replacement module is intended for specified 2002 and early-production 2003 Ford Explorer and Mercury Mountaineer gasoline applications with the 4.0L V6 or 4.6L V8. Confirm the vehicle build date, seven-terminal connector, OE number, two fuel outlets, flange, module height, and float-arm layout before ordering.

Fuel Pump Module Fitment for 2002–Early 2003 Explorer and Mountaineer

Verified coverage includes 2002 vehicles with the matching seven-pin connector and selected 2003 vehicles produced through approximately December 9–10, 2002. Later-production 2003 vehicles or assemblies with a different connector require another module.

Fitment Verification

• Confirm the 4.0L V6 or 4.6L V8 gasoline engine and read the production date from the door-jamb certification label.
• For 2003 vehicles, verify production through December 9 or before December 10, 2002 according to the application catalog.
• Match E2334M, FG0867, SP2334M, P76126M, or the verified Ford 1L2Z-9H307-LD series reference.
• Compare the seven-pin connector, two fuel outlets, flange, regulator, module height, reservoir, and float arm.

Module Functions and Included Components

• Electric in-tank pump supplies fuel to the engine-side delivery system.
• Integrated regulator, reservoir, inlet strainer, fuel-level sender, and float arm support pressure control and gauge reporting.
• Two fuel outlets and the seven-terminal connector are critical identification features.
• The verified configuration does not include a fuel-tank pressure sensor.

Symptoms and Diagnostic Checks

Measure fuel pressure before replacing the module. Test voltage and ground under load, inspect the fuse and relay, and check both fuel outlets and the seven-pin connector. Tank contamination, restricted lines, sender faults, EVAP problems, or an incorrect early-versus-late production module can produce similar symptoms.

Installation Notes

Relieve fuel-system pressure and disconnect the battery before opening the tank. Clean the tank and sealing surface, install a new compatible seal, keep the float arm clear, and reconnect both fuel lines correctly. Prime the system, inspect for leaks, measure pressure, and confirm normal gauge operation.
