Restore Your Truck’s Performance and Reliability
Is your 2007-2009 GMC Sierra 1500, Silverado, or other GM truck experiencing frustrating issues like stalling, hesitating on acceleration, or refusing to start altogether? Before you condemn the fuel pump, the real culprit is often a faulty Fuel Pump Control Module (FPCM). As a technician with over two decades of experience, I’ve seen this exact scenario play out countless times. These modules, often mounted on the frame rail, are exposed to harsh elements, leading to internal corrosion and electronic failure. This module, part number 25866052, is the definitive solution to restore proper fuel delivery and engine performance.
The biggest challenge with replacing an FPCM has always been the mandatory, and often expensive, trip to the dealership for programming. We eliminate that step entirely. When you purchase this module, we use your vehicle’s VIN to flash it with the very latest GM-approved software. This isn’t just a convenience; it ensures your new module has all the necessary updates to correct factory flaws and communicate perfectly with your truck’s powertrain control module (PCM). It arrives at your door ready for a true plug-and-play installation, saving you hundreds in diagnostic and programming fees.
From the Diagnostic Bay: The P069E Puzzle
A customer brought in his ’08 Silverado 1500 that would crank but not start. He had already replaced the in-tank fuel pump himself, but the problem persisted. His scanner showed a hard fault for code P069E (Fuel Pump Control Module Commanded OFF). A quick check confirmed the new pump was good. We then inspected the FPCM on the driver-side frame rail. It was heavily corroded. After installing one of our pre-programmed modules, the truck fired up on the first try and the code was gone. It’s a classic case I’ve diagnosed over 100 times—the module fails, cutting power and communication, making it seem like the pump is bad. Always check the FPCM first!
Is Your Vehicle Showing These Symptoms?
- ✔ Engine cranks but will not start
- ✔ Stalling while driving, especially under load
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes like P069E, P0230, or U0109 (Lost Communication with FPCM)
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery.
- ✔ Locate the Module: On most trucks like the Sierra/Silverado, the FPCM is mounted to the driver’s side frame rail, often near the spare tire. On other models, it may be on a rear crossmember or in the engine bay.
- ✔ Disconnect Connectors: Carefully press the release tabs and unplug the electrical connectors from the old module. Inspect the connectors for any corrosion or damage.
- ✔ Remove Old Module: Use a socket wrench to remove the bolts or nuts securing the FPCM to the frame.
- ✔ Install New Module: Mount your new, pre-programmed FPCM in the same location and secure it with the original hardware.
- ✔ Final Steps: Plug the electrical connectors firmly into the new module. Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds before starting to allow the system to prime.

Frequently Asked Questions
Why do you need my VIN?
Your VIN is required to load the exact, vehicle-specific software and the latest updates from GM. This ensures perfect compatibility and function without needing a trip to the dealer for programming.
Is this part difficult to install for a DIYer?
Not at all. For most trucks, it’s a simple bolt-off, bolt-on process that requires basic hand tools and can be completed in under 30 minutes. Since it’s pre-programmed, there’s no complex computer work involved.
Will this fix my P069E check engine light code?
In our extensive shop experience, a faulty FPCM is the most common cause of a P069E code on these GM vehicles. While other issues can cause it, replacing the module is the most probable fix.
Where is this module located on my 2008 Sierra?
On the 2007-2009 Sierra and Silverado, the FPCM is almost always found mounted on the outer side of the driver-side frame rail, typically just ahead of the rear axle.
Is this a new or used part?
This is a brand new replacement part, not a salvaged or rebuilt unit. It is loaded with fresh, updated software to provide long-lasting reliability.
