Restore Your Vehicle’s Performance and Reliability
Is your 2009 Buick Enclave or other GM vehicle suddenly stalling, hesitating, or refusing to start? Before you condemn the fuel pump, the real culprit is often the Fuel Pump Control Module (FPCM). As a technician with over two decades of experience, I’ve seen countless vehicles sidelined by this small but critical component. The FPCM is the brain of your fuel delivery system, precisely managing the voltage sent to the fuel pump. When it fails, you get inconsistent fuel pressure, leading to a host of frustrating and potentially dangerous engine performance issues.
This isn’t just a replacement part; it’s a complete solution. We take the hassle and expense 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, ready for a direct, plug-and-play installation. You get to skip the costly trip to the dealership for programming, saving you both time and money. This is the definitive fix for getting your truck or SUV running smoothly again.
From the Diagnostic Bay: The Intermittent Stall
A customer brought in his 2008 Sierra 1500 with a problem that was driving him crazy: it would run perfectly for days, then suddenly stall at a stoplight. No check engine light, no consistent codes—just a random, intermittent no-start. He’d already replaced the fuel pump with no luck. After hooking up my scan tool and monitoring live data, I noticed the fuel pump duty cycle was dropping to zero right before the stall. The pump was fine; the signal telling it what to do was disappearing. The FPCM, mounted on the frame rail, had developed an internal fault from years of heat and vibration. A new, pre-programmed 2009 Enclave Fuel Pump Control Module (which shares the same architecture) had him back on the road permanently, stall-free.
Common Signs of a Failing FPCM
If your vehicle is experiencing any of the following, a faulty fuel pump control module is a likely cause. A failing FPCM can often trigger diagnostic trouble codes (DTCs) such as P069E, U0109, or P0230.
- ✔ Engine stalling, especially when coming to a stop or at idle
- ✔ Extended cranking time before the engine starts
- ✔ Complete no-start condition where the engine turns over but won’t fire
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light illumination with fuel system-related codes
A Straightforward Guide to Installation
Installing your new 2009 Enclave Fuel Pump Control Module is a manageable job for a DIYer with basic tools. Location varies by model, but it’s typically mounted on the vehicle’s frame or crossmember.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most GM trucks and SUVs (like the Sierra, Tahoe, Escalade), the FPCM is on the driver’s side frame rail, near the spare tire. On crossovers (like the Enclave, Acadia, Traverse), it’s often on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connector(s) from the old module. Then, unbolt the module from the frame. These bolts can sometimes be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed FPCM into the same location. Ensure it is mounted securely.
- Reconnect and Finalize: Plug the electrical connector firmly into the new module. Reconnect the negative battery terminal. The vehicle is now ready to start with no further programming required.

Frequently Asked Questions
Why do you need my VIN to program the module?
Your VIN allows us to load the exact, vehicle-specific software and the latest GM updates onto the module. This ensures perfect communication with your vehicle’s other computers, like the ECM and BCM, for flawless operation right out of the box.
Is this part really plug-and-play?
Yes. Because we program it before shipping, you do not need a scan tool or a trip to the dealer. Simply install the module, and your vehicle is ready to go. It’s the easiest way to complete this repair.
Where is the FPCM located on my 2009 Enclave?
On the 2009 Buick Enclave, as well as the similar Acadia and Traverse, the Fuel Pump Control Module is typically mounted to the rear subframe crossmember, accessible from underneath the vehicle.
Will this fix a P069E trouble code?
Yes, the DTC P069E (Fuel Pump Control Module Requested MIL Illumination) is one of the most common codes indicating a failed FPCM. Replacing the module with this pre-programmed unit is the correct and definitive repair for this code.
Is this different from the fuel pump driver module?
No, the terms Fuel Pump Control Module (FPCM) and Fuel Pump Driver Module (FPDM) are often used interchangeably. They both refer to the same component that controls the vehicle’s fuel pump.
