Restore Your Vehicle’s Performance and Reliability
Is your 2009 Buick Enclave or other GM vehicle experiencing frustrating issues like stalling, hesitation on acceleration, or a dreaded no-start condition? Before you consider replacing the entire fuel pump—a costly and labor-intensive job—the culprit is often a faulty Fuel Pump Control Module (FPCM). As a technician with over two decades of experience, I’ve seen this exact scenario hundreds of times. This module is the electronic brain that tells your fuel pump how much fuel 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 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 already installed, eliminating the need for a costly trip to the dealership for programming. This is the most efficient way to get your truck or SUV back to factory-spec operation.
A Technician’s Notebook
I remember a 2008 Silverado that came into the shop with a classic “bad fuel pump” complaint. The owner had already replaced the in-tank pump himself, but the truck would still randomly stall and show ‘Reduced Engine Power’ on the dash. He was frustrated and out of ideas. After hooking up the scan tool, I saw a U0109 code—Lost Communication with Fuel Pump Control Module. Instead of diving into the fuel tank again, we checked the FPCM mounted on the frame rail. It was heavily corroded from road salt and moisture. We installed one of these pre-programmed modules, and the truck ran perfectly. It’s a powerful reminder to always check the FPCM first; it can save you hundreds of dollars and hours of unnecessary work.
Is Your Vehicle Showing These Symptoms?
- ✔ Engine cranks but refuses to start
- ✔ Vehicle stalls unexpectedly, especially under load
- ✔ Hesitation or stumbling during acceleration
- ✔ ‘Reduced Engine Power’ message on the instrument cluster
- ✔ An active Check Engine Light with codes like P069E, P0230, or U0109
- ✔ A buzzing or whining noise from the fuel pump that is inconsistent
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle with basic tools. While the exact location varies slightly by model, the process is generally the same. For the 2009 Enclave, you’ll typically find it mounted on or near the rear crossmember.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FPCM. On most GM trucks and SUVs like the Tahoe or Sierra, it’s mounted on the driver’s side frame rail, just in front of the spare tire. On crossovers 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 module from the frame or chassis. These bolts can sometimes 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 mounted.
- Reconnect Everything: Plug the electrical connectors firmly into the new module. 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 vehicle. Your fuel delivery issues should be resolved.

Frequently Asked Questions
Why does this module need to be programmed?
Modern vehicles use a communication network (CAN bus) where components are coded to the vehicle’s specific VIN. Programming ensures this module communicates correctly with your vehicle’s main computer (ECU/PCM) for proper fuel delivery and diagnostics. We do this for you before shipping.
Where is the VIN located on my vehicle?
You can find your 17-digit VIN on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this a difficult part to replace myself?
For most individuals with basic mechanical skills and tools, this is a very manageable repair that can be completed in under an hour. Since our module is pre-programmed, no special electronic tools are needed.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function in your vehicle. We will contact you after your purchase to get this information to prevent any delays.
Will this fix a P069E code?
Yes, a faulty FPCM is the most common cause of a P069E (Fuel Pump Control Module Requested MIL Illumination) diagnostic trouble code. Replacing it with this pre-programmed unit is the correct fix in most cases.
