Fuel Pump Driver Module For 08-09 Chevrolet Avalanche GMC Cadillac Hummer Saturn

Fuel Pump Driver Module for Chevrolet, GMC, Cadillac, Hummer, Saturn

This fuel pump driver module controls the electric fuel pump on 2008-2009 Chevrolet Avalanche, GMC, Cadillac, Hummer, and Saturn vehicles. It replaces a failed module and restores consistent fuel pressure and pump function.

Overview

The fuel pump driver module is an electronic control unit that regulates voltage to the in-tank fuel pump based on engine demand. When the original module fails on 2008-2009 model year trucks and SUVs from Chevrolet, GMC, Cadillac, Hummer, and Saturn, the pump may run erratically or stop entirely. This replacement module plugs into the existing harness and returns proper fuel pressure for starting, idle, and full-throttle operation.

Built For Performance

• Direct plug-and-play connector matches OEM wiring for a quick install
• Solid-state circuitry handles high-current draw without voltage drop
• Sealed housing protects internal components from road spray and moisture
• Thermal management prevents overheating during extended low-fuel operation
• Mounts in the factory location near the spare tire or frame rail
• Tested to maintain correct voltage output across a full pump cycle

Fits These Machines

• for Chevrolet Avalanche 2008-2009
• for GMC Sierra 1500 2008-2009
• for Cadillac Escalade 2008-2009
• for Hummer H2 2008-2009
• for Saturn Vue 2008-2009

On-The-Job Use

• Getting a truck back on the road when the original module leaves you stranded
• Fixing a hard-start or no-start condition traced to fuel pump control
• Addressing a sudden loss of power while towing or under load
• Resolving intermittent fuel gauge or pump prime faults
• Performing a preventive swap when the module shows corrosion or cracks

Good To Know

Q: Can a failing driver module cause the fuel pump to run constantly? A: Yes, a stuck relay or shorted circuit in the module may keep the pump running with the key off, draining the battery and wearing out the pump prematurely.

Q: Do I need to reprogram the module after installation? A: Typically no, this module is plug-and-play and does not require dealer programming, but confirming voltage values with a scan tool after install is a good practice.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
