If your 2009 GMC Acadia or other compatible GM vehicle is experiencing frustrating issues like stalling, hesitation, or a complete no-start condition, a failing Fuel Pump Control Module (FPCM) is a very likely culprit. As a technician with over two decades of experience, I’ve seen these symptoms countless times. The FPCM, also known as a Fuel System Control Module (FSCM), is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to poor performance and leaving you stranded.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra cost out of the repair by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN). This means it arrives at your door with the latest GM software updates already installed. You can skip the expensive trip to the dealership for programming—a step that is absolutely required for a non-programmed module to function. This direct-fit module, part number 25967325, ensures your fuel system operates exactly as the manufacturer intended.
From the Diagnostic Bay: The Intermittent Stall
A customer brought in a 2009 Acadia with a tricky complaint: it would run perfectly for days, then suddenly stall at a stoplight and refuse to restart for 10-15 minutes. Initial fuel pressure tests in the bay were normal. The check engine light wasn’t on, but a deep scan revealed a history code U0109 – ‘Lost Communication with Fuel Pump Control Module.’ These modules, often mounted on the frame rail, are exposed to water, salt, and vibrations, leading to internal corrosion and intermittent connection failures. Replacing the FPCM with a pre-programmed unit permanently solved the phantom stalling issue.
Is Your GM Vehicle Showing These Symptoms?
A faulty FPCM can manifest in several ways. If you’re noticing any of the following, this module is the likely solution.
- ✔ Engine cranks but will not start
- ✔ Vehicle starts and then immediately stalls
- ✔ Severe engine hesitation or sputtering during acceleration
- ✔ Loss of power under load, such as climbing a hill
- ✔ An active Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109
- ✔ Reduced fuel economy
A Straightforward Guide to Installation
Installing your new, pre-programmed FPCM is a manageable job for a DIYer with basic tools. While the exact location varies by model (check your service manual), the general process is consistent.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Module: On most GM trucks and SUVs (like the Tahoe, Sierra, Silverado), the FPCM is mounted on the driver’s side frame rail, near the spare tire. On vehicles like the Acadia or Traverse, it’s often on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note their orientation. Then, unbolt the old module from its mounting bracket. These bolts can be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Ensure it is securely fastened.
- Reconnect and Finalize: Plug the electrical connectors firmly into the new module. Reconnect your battery’s negative terminal. Your vehicle is now ready to start with no additional programming needed.

What is the purpose of a Fuel Pump Control Module?
What is the purpose of a Fuel Pump Control Module?
The FPCM regulates the voltage sent to the electric fuel pump. Instead of running the pump at full speed all the time, the module adjusts its speed based on engine demand. This provides precise fuel pressure, improves the lifespan of the fuel pump, and enhances fuel efficiency.
Why do I have to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to program the module with the exact software and calibrations for your specific vehicle’s engine, transmission, and options. This ensures it works perfectly right out of the box, without requiring a trip to a dealer for expensive programming.
Can I install this module myself?
Yes, this is a common DIY repair. The module is typically in an accessible location on the vehicle’s frame or crossmember. With basic hand tools and our pre-programmed module, you can complete the job without needing specialized diagnostic equipment.
What happens if I install a module that isn’t programmed?
A non-programmed FPCM will not operate the fuel pump. The vehicle will crank but will not start because the module cannot communicate with the vehicle’s main computer (ECM/PCM). Our service saves you from this problem.
Will this fix a check engine light for code P069E?
Yes, in most cases. DTC P069E (Fuel Pump Control Module Requested MIL Illumination) is a very common code indicating a fault within the FPCM itself. Replacing the module is the standard, effective repair for this code.
