Restore Your Vehicle’s Reliability and Performance
There’s nothing more frustrating than a vehicle that won’t start, stalls unexpectedly, or hesitates under acceleration. If your 2009 Buick Enclave or another compatible GM vehicle is experiencing these issues, a faulty Fuel Pump Control Module (FPCM) is a very common cause. This critical component, also known as a Fuel System Control Module (FSCM), regulates the voltage sent to your fuel pump. When it fails, it can starve your engine of fuel, leading to a host of drivability problems and leaving you stranded. In my 20+ years as a technician, I’ve seen these modules, often mounted on the frame rail and exposed to the elements, fail due to corrosion, vibration, and heat cycling.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and the expensive trip to the dealership out of the equation. By providing us with your vehicle’s VIN at checkout, you will receive a 2009 Enclave Fuel Pump Module that has been professionally flashed with the latest GM-certified software specifically for your vehicle. This ensures perfect communication with your vehicle’s computer systems and restores factory performance right out of the box.
Case Study: A Tricky Diagnosis
I remember a 2008 Tahoe that came into my bay with an intermittent stalling issue. The owner had already replaced the in-tank fuel pump twice, convinced it was the problem. The truck would run fine for days, then suddenly die at a stoplight. No codes were stored initially. We checked fuel pressure, and it was erratic. Instead of just throwing another pump at it, we monitored the command signal to the FPCM. We found the module was getting power and ground, but its output to the pump was dropping off randomly. The module itself was overheating. A new, properly programmed FPCM fixed the issue permanently. It’s a classic example of how diagnosing the entire system saves time and money.
Is Your GM Truck or SUV Showing These Signs?
A failing FPCM can mimic other fuel system problems. Here are the most common symptoms and diagnostic trouble codes (DTCs) I’ve seen associated with this part:
- ✔ Vehicle cranks but will not start (crank-no-start).
- ✔ Engine stalls while driving, especially when coming to a stop.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Reduced engine power and poor fuel economy.
- ✔ Check Engine Light illuminated with codes such as P069E, U0109, P0230, or P025A.
- ✔ A buzzing or whining noise from the fuel pump that is inconsistent.
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIY enthusiasts can handle with basic tools. While the exact location varies by model, the process is generally similar. Always consult a service manual for your specific vehicle.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs (Tahoe, Silverado, Sierra), it’s mounted to the driver’s side frame rail, often near the spare tire. On crossovers (Enclave, Traverse, Acadia), it’s typically on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connector. Be sure to press the release tab to avoid breaking it. Then, remove the bolts or nuts (usually 2 or 3) securing the module to the frame.
- Install the New Module: Mount your new, pre-programmed FPCM in the same location and secure it with the original hardware.
- Reconnect: Plug the electrical connector back in until it clicks securely. Reconnect the negative battery terminal.
- Final Check: Turn the key to the ‘On’ position for a few seconds to allow the system to prime, then start the engine. Your vehicle should now run smoothly.

Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) is required so we can program the module with the exact software and calibrations for your specific vehicle’s configuration. This ensures 100% compatibility and prevents communication errors, making it a true plug-and-play installation.
Is this part difficult to install myself?
For most individuals with basic mechanical skills, this is a very manageable job. It typically involves removing a few bolts and one electrical connector. The main challenge can be accessing the module on the frame, but no special tools are required.
What happens if I install it without programming?
An unprogrammed module will not work. The FPCM must be able to communicate with the Engine Control Module (ECM) and other vehicle systems. Without the correct VIN-specific software, your vehicle will likely not start or will run very poorly.
How is this different from a part from the local auto parts store?
Most aftermarket modules sold locally are blank and require expensive programming with specialized scan tools at a dealership or qualified shop. Our service includes this programming, saving you time, towing fees, and additional labor costs.
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 fault with the FPCM. While you should always perform a full diagnosis, a faulty FPCM is the leading cause for this code.
