Restore Your Vehicle’s Fuel System and End Stalling Issues
Is your GMC Acadia or other GM vehicle suddenly stalling, hesitating during acceleration, or refusing to start? These are classic signs of a failing Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This critical component regulates the voltage sent to your fuel pump, ensuring your engine receives the precise amount of fuel it needs. When it fails, it can leave you stranded and facing a frustrating diagnosis. In my 20+ years as a technician, I’ve seen countless vehicles sidelined by this exact issue, often caused by the module’s exposed location on the frame rail where it’s vulnerable to water, salt, and corrosion.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and high cost of dealership programming out of the equation. Simply provide us with your vehicle’s VIN after purchase, and we will flash this module with the latest, most stable software directly from GM. This ensures perfect compatibility and restores your vehicle’s performance and reliability. This is the most efficient way to install a new 2009 Acadia Fuel Pump Control Module and get back on the road with confidence.
Case Study: A Tricky Diagnosis
A customer brought in a 2009 GMC Acadia with an intermittent no-start condition and a P069E code stored in the ECM. The fuel pressure would sometimes be perfect, and other times drop to zero. After confirming the fuel pump itself was functional, I inspected the FPCM located on the rear crossmember. While the module looked fine externally, the connector was packed with green corrosion from years of exposure to road grime and moisture. This poor connection was causing the erratic voltage to the pump. Replacing it with a pre-programmed module like this one, and applying dielectric grease to the new connector, provided a permanent, reliable fix. It’s a repair I’ve done hundreds of times on these platforms.
Common Symptoms of a Failing FPCM
- ✔ Engine cranking but failing to start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Hesitation or sputtering during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ An illuminated Check Engine Light
- ✔ Common Diagnostic Trouble Codes (DTCs): P069E, P0230, P064A, or U0109 (Lost Communication with FPCM)
A Straightforward Guide to Installation
Replacing your 2009 Acadia Fuel Pump Control Module is a job most DIY mechanics can handle with basic tools. The location varies slightly by model but is generally accessible.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and large SUVs (Tahoe, Silverado, Escalade), the FPCM is mounted on the driver’s side frame rail, often near the spare tire. On crossovers (Acadia, Traverse), it’s typically on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connector. You may need to press a release tab. Then, remove the bolts or nuts (usually 10mm or 13mm) securing the old module to the frame.
- Clean the Area: Before installing the new module, clean the mounting surface and the electrical connector pins to ensure a solid connection and proper grounding. Applying a small amount of dielectric grease to the connector seal is highly recommended.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Reconnect the electrical harness, ensuring it clicks securely.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds before starting the engine to allow the system to prime. Start the vehicle and check for proper operation.

Frequently Asked Questions about the 2009 Acadia Fuel Pump Control Module
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is required so we can program the module with the exact software calibration specified by GM for your vehicle’s specific configuration. This ensures seamless communication and perfect operation right out of the box.
Do I need any special tools to install this?
No special tools are required. Basic hand tools like a socket set and ratchet are all you need for the physical installation. Because we pre-program the module, you do not need any expensive dealership scan tools.
Where is the FPCM located on my 2009 Acadia?
On the 2009 GMC Acadia and similar platforms like the Traverse and Enclave, the fuel pump control module is typically mounted to the rear subframe or crossmember, near the fuel tank.
Is this part a direct replacement for part number 20759945?
Yes, this module is a fully compatible, direct replacement for a wide range of GM part numbers, including 20759945, 25967325, 13501024, and several others listed in the description.
What happens if I install it without programming?
An unprogrammed FPCM will not work. The vehicle’s computer systems will not recognize it, and the fuel pump will not operate. This will result in a no-start condition. Our service eliminates this problem by delivering a part that is 100% ready for installation.
