Restore Your Truck’s Reliability and Performance
Is your 2008-2009 Chevrolet Avalanche 1500 experiencing sudden stalling, refusing to start, or showing a ‘Service Fuel System’ message on the dash? These are frustrating and often dangerous symptoms of a failing Fuel Pump Control Module (FPCM). Located on the frame rail, the original module is highly susceptible to corrosion from road salt, water, and debris, leading to intermittent or complete failure. This replacement FPCM is the definitive, long-term solution to restore your truck’s fuel delivery system to perfect working order.
Unlike parts that require a trip to the dealership, this module arrives at your door fully programmed with the latest GM software updates. We flash it specifically to your vehicle’s VIN, ensuring it’s a true plug-and-play component. You can get your truck back on the road quickly without the extra cost and hassle of dealer programming.
From the Diagnostic Bay
I remember a customer with an ’08 Sierra who was about to spend over $800 on a new in-tank fuel pump replacement. His truck would crank but not start intermittently. He was convinced the pump was dead. I advised him to check the FPCM first. We found the original module’s casing was swollen and the pins were green with corrosion—a classic failure. We swapped in a pre-programmed FPCM just like this one in under 15 minutes. The truck fired right up and has run flawlessly since. That simple check saved him a lot of money and a much more intensive repair. Always check the FPCM before condemning the fuel pump on these GM trucks.
Common Signs of a Failing FPCM
If your vehicle is exhibiting any of these symptoms, a faulty fuel pump control module is the most likely cause. Replacing the 2008-2009 Avalanche FPCM can resolve these issues:
- âś” Engine cranks but will not start
- âś” Stalling while driving, especially under load
- âś” Hesitation or stumbling during acceleration
- âś” Rough or inconsistent idle
- âś” Check Engine Light (CEL) with codes like P069E, U0109, or P0230
- âś” ‘Service Fuel System’ message on the instrument cluster
- âś” A noticeable lack of engine power
A Straightforward Guide to Installation
Installing your new 2008-2009 Avalanche FPCM is a simple process that most DIYers can complete with basic hand tools. Since it comes pre-programmed, no special electronic tools are needed.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most compatible trucks and SUVs, including the Avalanche, the FPCM is mounted to the driver’s side (LH) frame rail, typically near the spare tire.
- Remove the Old Module: Unplug the electrical connector. Be gentle, as the locking tab can be brittle. Then, remove the bolts holding the module to the frame.
- Install the New Module: Mount your new, pre-programmed FPCM onto the frame rail and tighten the bolts securely.
- Connect and Finalize: Plug the electrical connector firmly into the new module. You should hear a ‘click’ as it seats. Reconnect the negative battery terminal.
- Start the Vehicle: Turn the key to the ‘On’ position for 10 seconds to allow the system to prime, then start the engine. Your fuel system should now operate correctly.
