Restore Your Truck’s Power and Reliability
Is your 2007-2009 GMC Sierra 1500 experiencing frustrating issues like stalling, hesitation under acceleration, or a dreaded crank-no-start condition? Before you consider replacing the entire fuel pump, the problem often lies with a failed 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 optimal fuel pressure and engine performance. When it fails, it can mimic a bad fuel pump, leading to costly and incorrect repairs.
This is a direct-replacement FPCM, part number 25854536, designed to solve these exact problems. The best part? We handle the programming for you. Simply provide your vehicle’s VIN at checkout, and our technicians will flash the module with the latest, most stable software updates directly from GM. This means it arrives at your door ready for a true plug-and-play installation, saving you a trip to the dealership and hundreds in programming fees. Get your truck running like new again with a reliable, properly configured fuel system.
Case Study: The Sierra That Wouldn’t Start
A customer brought in an ’08 Sierra 1500 that would crank but not fire up. He had already replaced the in-tank fuel pump himself, but the problem persisted. His scanner showed a U0109 (Lost Communication with Fuel Pump Control Module) and a P069E (Fuel Pump Control Module Requested MIL Illumination). Instead of throwing more parts at it, we went straight to the FPCM, located on the driver-side frame rail. It was heavily corroded from years of exposure to road salt and moisture—a common failure point I’ve seen on hundreds of these GMT900 trucks. We installed a new, pre-programmed module, and the truck fired up on the first try. This simple swap saved him hours of diagnostic headaches and the cost of another unnecessary part.
Common Signs of a Failing FPCM
- ✔ Engine cranks but will not start
- ✔ Stalling, especially when coming to a stop or under load
- ✔ Hesitation or sputtering during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
- ✔ A fuel pressure gauge showing low or erratic readings
A Straightforward Guide to Installation
Installing your new 2007-2009 Sierra 1500 FPCM is a job most DIYers can handle in their own driveway. The module is typically located on the driver-side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FPCM mounted to the vehicle’s frame. On most Sierra/Silverado models, it’s on the outside of the driver-side frame rail.
- Disconnect Connectors: Carefully press the release tabs and unplug the electrical connectors from the old module. Inspect them for corrosion or damage.
- Unbolt the Old Module: Remove the bolts or nuts securing the FPCM to the frame. These can sometimes be rusted, so a little penetrating oil might be helpful.
- Mount the New Module: Bolt your new, pre-programmed FPCM into place. Ensure it’s secure.
- Reconnect and Finalize: Plug the electrical connectors firmly into the new module. Reconnect the negative battery terminal. The vehicle may need to cycle the key a few times to re-pressurize the fuel system before starting.

Frequently Asked Questions
What is an FPCM and what does it do?
The Fuel Pump Control Module (FPCM) is a small computer that controls the voltage sent to your vehicle’s electric fuel pump. This allows it to precisely manage fuel pressure for better efficiency and performance, rather than having the pump run at full speed all the time.
Why does this module need to be programmed to my VIN?
Programming the FPCM with your Vehicle Identification Number (VIN) ensures it has the correct software and calibrations for your specific truck’s engine, fuel system, and other electronics. This prevents compatibility issues and ensures it functions as the factory intended.
Can I install this myself?
Absolutely. Because we program the module before shipping, it’s a plug-and-play part. Installation typically involves unbolting the old module from the frame rail and plugging in the new one, which is a common DIY repair.
Is this part a common failure on my 2007-2009 Sierra 1500?
Yes, the FPCM is a known failure point on this generation of GM trucks. Its location on the frame rail exposes it to water, salt, and debris, which can lead to corrosion and internal failure over time.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function correctly in your vehicle. Please be sure to send us your 17-digit VIN after purchase to avoid delays.
