Restore Your Truck’s Fuel System with a Reliable, Programmed Module
If your 2008-2009 Chevrolet Avalanche 1500 is experiencing frustrating issues like stalling, hesitation during acceleration, or a dreaded no-start condition, the culprit is often a failing Fuel Pump Control Module (FPCM). This critical component, also known as a Fuel System Control Module (FSCM), regulates the voltage sent to your fuel pump, ensuring your engine gets the precise amount of fuel it needs. When it fails, it can leave you stranded. This isn’t just a replacement part; it’s a complete, ready-to-install solution for your truck’s long-term health.
From the Diagnostic Bay: The All-Too-Common No-Start Scenario
I’ve seen this hundreds of times in my shop. A customer’s truck, usually a Silverado, Tahoe, or Avalanche from this era, gets towed in. It cranks perfectly but won’t fire up. The owner often suspects the fuel pump, but a quick scan with a professional tool reveals DTCs like P069E (Fuel Pump Control Module Commanded On) or U0109 (Lost Communication with FPCM). The root cause? The original FPCM, mounted on the driver-side frame rail, has succumbed to years of exposure to water, salt, and road debris, causing internal corrosion and failure. This isn’t just a theory; it’s a pattern I’ve diagnosed and fixed time and time again.
The Plug-and-Play Advantage: VIN-Programmed for Your Vehicle
The biggest headache with replacing modern electronic modules is the need for expensive, dealer-only programming. We eliminate that problem entirely. Before this part ships, our technicians will flash it with the latest GM software updates, specifically matched to your vehicle’s VIN. This means the 2008-2009 Avalanche FPCM arrives at your door ready for a direct, bolt-in installation. You save time, money, and the hassle of a trip to the dealership. It’s the most efficient way to get your truck back on the road and running right.
Is Your Avalanche Showing These Signs of FPCM Failure?
A faulty FPCM can cause a range of symptoms beyond a simple no-start. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Severe engine hesitation or sputtering
- ✔ Reduced Engine Power message on the dash
- ✔ An active Check Engine Light with codes like P069E, P0230, or U0109
- ✔ Inconsistent fuel pressure readings
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle with basic tools. Since we’ve handled the programming, the physical swap is all that’s left.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the Module: On most GM trucks and SUVs of this generation, including the Avalanche, the FPCM is mounted to the driver-side frame rail, typically above the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, remove the bolts or nuts securing the old module to the frame. It may be corroded, so some penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Ensure it is securely fastened to the frame.
- Reconnect and Finalize: Plug the electrical connectors firmly into the new module. Reconnect your battery’s negative terminal. The vehicle may require a few key cycles to fully recognize the new module before starting.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential for us to program the module with the correct, vehicle-specific software and the latest updates from GM. This ensures perfect compatibility and function right out of the box.
Is this part difficult to install for a DIYer?
No. Since we handle all the programming, the physical installation is very straightforward. It involves unbolting the old module from the frame rail, plugging in the new one, and bolting it back on. Basic hand tools are all that’s required.
Where is the FPCM located on my 2008 Avalanche?
The Fuel Pump Control Module is typically mounted on the outside of the driver-side frame rail, often near or above the spare tire area. Its location makes it vulnerable to the elements, which is a common reason for its failure.
Will this fix a check engine light with code P069E?
Yes, in the vast majority of cases. The diagnostic trouble code P069E specifically points to a performance or circuitry issue within the Fuel Pump Control Module. Replacing the faulty module with our pre-programmed unit is the correct repair for this code.
What happens if I install a module that isn’t programmed?
An unprogrammed module will not communicate correctly with your vehicle’s Engine Control Module (ECM). This will result in a no-start condition, persistent error codes, and improper fuel pump operation. Our pre-programming service prevents this entirely.
