Description Specifications FAQs Return & Support

Extended cranking, a no-start condition, stalling, weak acceleration, low fuel pressure, or an inaccurate fuel gauge can indicate a failing in-tank module after electrical and pressure tests are completed. The BDFHYK E3943M fuel pump module is an OE-style replacement for specified 1997–2000 Chevrolet S10, GMC Sonoma, and Isuzu Hombre pickups with the 2.2L engine. Confirm the VIN code, tank, flange, connector, line ports, module depth, and OE number before installation.

E3943M Fitment for S10, Sonoma, and Hombre 2.2L

  • 1997–2000 Chevrolet S10 pickup, 2.2L L4
  • 1997–2000 GMC Sonoma pickup, 2.2L L4
  • 1997–2000 Isuzu Hombre pickup, 2.2L L4

Fitment must be confirmed from the VIN, fuel-tank configuration, removed module, and OE/interchange number. Similar vehicles can use different flanges, connectors, fuel-line arrangements, module depths, or sender layouts.

What the E3943M Assembly Does

Supplies fuel from the tank and measures fuel level through the module sender. This is an OE-style aftermarket replacement intended to restore the original tank-side function when the application and physical module match.

Fitment Verification Before Installation

  • 2.2L engine and VIN code
  • Tank and flange configuration
  • Electrical connector and fuel-line ports
  • Module height and reservoir shape
  • Float arm and sender layout
  • E3943M or listed interchange number

Diagnosis Before Replacing the Fuel Module

  • Measure fuel pressure against the vehicle service specification.
  • Check fuse, relay, power, ground, and connector voltage drop.
  • Inspect fuel lines, regulator operation, and tank contamination.
  • Separate gauge-circuit faults from pump-pressure faults.

A failed fuel pump module should be confirmed with pressure, voltage, ground, and circuit testing. Do not replace the module solely because the engine does not start or the fuel gauge is inaccurate.

Installation and Post-Installation Checks

Relieve pressure, disconnect the battery, clean the tank opening, replace the seal, prime, and verify leaks, pressure, starting, and gauge operation. Do not energize an electric fuel pump outside fuel. Follow the vehicle service procedure for tank removal, sealing, and pressure testing.

Application Summary

Referenced E3943M applications commonly specify approximately 41–47 psi; diagnose pressure using the vehicle service specification. Compare all pictured components and listed references with the removed assembly before ordering or installation.
