Fuel Pump Module Assembly E3781m For Pontiac Vibe Toyota Corolla Matrix L4 1.8l,L4 2.4l 2005-2013 Engine 1.8l/2.4l/L4

Extended cranking, low measured fuel pressure, hesitation during acceleration, intermittent stalling, or an inaccurate fuel gauge can indicate an in-tank module fault after the fuse, relay, voltage supply, ground, wiring, and fuel lines have been tested. This E3781M replacement module covers specified Pontiac Vibe, Toyota Corolla, and Toyota Matrix 1.8L or 2.4L applications, but the valid year range changes by model and engine. Confirm the exact year, engine, OE number, four-terminal connector, single outlet, flange, sender calibration, module height, and float-arm geometry before ordering.

Fuel Pump Module Fitment by Model and Engine

Verified catalog coverage includes Pontiac Vibe 1.8L applications from 2005–2010 and 2.4L applications from 2009–2010; Toyota Corolla 1.8L applications from 2005–2018 and selected 2.4L applications from 2009–2010; and Toyota Matrix 1.8L applications from 2005–2013 and 2.4L applications from 2009–2013. Engine size and a broad 2005–2013 range alone are not sufficient because OE numbers and sender calibrations vary.

Fitment Verification

• Confirm the exact Vibe, Corolla, or Matrix model year and the 1.8L or 2.4L engine.
• Match E3781M, MU1718, F2792A, FG1640, FG0938, FG1299, SP9047M, SP9165M, or P76659M.
• Compare the single four-terminal electrical connector and fuel outlet with the removed module.
• Verify the flange, reservoir, module height, float-arm direction, and application-specific sender calibration.

Module Functions and Service Components

• Electric 12-volt in-tank pump supplies fuel to the engine-side delivery system.
• Fuel-level sending unit and float arm report tank level to the instrument cluster.
• Reservoir and inlet strainer support fuel pickup around the pump inlet.
• The verified module family is listed without an integrated pressure sensor; replace the tank seal with the correct application-specific seal.

Symptoms and Diagnostic Checks

Measure fuel pressure before replacing the module. Test voltage and ground at the connector under load, inspect the fuse and relay, and check the fuel line and sender circuit. Incorrect model-year coverage, the wrong engine-specific OE number, damaged wiring, a restricted line, tank contamination, or an engine-management fault can create similar symptoms.

Installation Notes

Relieve fuel-system pressure, disconnect the battery, and access or support the tank safely. Clean the tank and sealing surface, install the correct new seal, keep the float arm clear, and secure the module evenly. Prime the system, inspect the flange and outlet for leaks, measure fuel pressure, and confirm that the gauge moves through its normal range.
