Restore Your Vehicle’s Reliability and Performance
Is your 2009 Buick Enclave or other GM vehicle suddenly stalling, hesitating during acceleration, or refusing to start? Before you condemn the fuel pump, the real culprit is often the Fuel Pump Control Module (FPCM), also known as a Fuel Pump Driver Module. This critical component regulates the voltage sent to your fuel pump, ensuring precise fuel pressure for optimal engine performance. When it fails, it can leave you stranded and frustrated. This module is a direct-fit, reliable solution to get you back on the road with confidence.
Case Study: A Tricky Diagnosis
I remember a 2009 GMC Acadia that came into my shop with classic ‘bad fuel pump’ symptoms: it would crank but not start, and sometimes it would stall at idle. The owner had already replaced the fuel pump himself, but the problem persisted. A quick scan showed a U0109 code—Lost Communication With Fuel Pump Control Module. Instead of throwing more parts at it, we inspected the FPCM located on the frame rail. It was heavily corroded from road salt and moisture. We installed a new, pre-programmed module, and the vehicle fired right up and ran perfectly. This simple part saved the customer hundreds in further misdiagnosis.
The Plug-and-Play Advantage: Programmed Specifically for You
One of the biggest hurdles in replacing electronic modules is the need for expensive dealership programming. We eliminate that step entirely. When you purchase this 2009 Enclave Fuel Pump Module, we use the Vehicle Identification Number (VIN) you provide to flash the unit with the latest, most stable software updates directly from GM. This means the part arrives at your door ready for installation, with no extra tools or trips to the mechanic required. It’s a true plug-and-play fix that restores factory performance.
Is Your Vehicle Showing These Symptoms?
A failing FPCM can cause a variety of confusing issues. If you’re experiencing any of the following, this module is a likely solution:
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly, especially when warm
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
A Straightforward Guide to Installation
Replacing your 2009 Enclave Fuel Pump Module is a job most DIYers can handle in their own driveway. While the exact location varies by model (see fitment list), the process is generally the same.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most GM trucks and SUVs, the FPCM is mounted to the driver-side frame rail, near the spare tire. On vehicles like the Enclave or Traverse, it may be on a rear crossmember. Check your specific model for its location.
- Disconnect and Remove: Unplug the electrical connectors. Be gentle with the locking tabs, as they can become brittle. Then, unbolt the old module from the frame.
- Install the New Module: Bolt the new, pre-programmed module in place. Reconnect the electrical harnesses, ensuring they click securely into place.
- 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 initialize. Start the vehicle and check for proper operation.

Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN is required so we can program the module with the exact software and calibrations for your vehicle’s specific configuration. This ensures perfect compatibility and function without needing a trip to the dealer.
Is this part difficult to install?
No, installation is straightforward for most people with basic tools. It involves unbolting the old module and plugging in the new one. Since it comes pre-programmed, no special electronic tools are needed.
What happens if I install it without programming?
An unprogrammed Fuel Pump Control Module will not work correctly. It may prevent the vehicle from starting or cause severe performance issues, as it cannot communicate properly with the vehicle’s other computers.
Where is the FPCM located on my 2009 Enclave?
On the 2009 Buick Enclave, the FPCM is typically mounted to the rear crossmember, accessible from underneath the vehicle.
Is this the same as a fuel pump relay?
No. A relay is a simple on/off switch. This is a computer module that precisely controls the fuel pump’s speed by varying voltage, which is essential for modern fuel injection systems.
