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 even refusing to start? Before you consider replacing the entire 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 this exact scenario countless times. This module, also known as an FSCM, is the brain behind your fuel delivery system, and when it fails, it can mimic a bad fuel pump, leading to incorrect and costly repairs.
We offer a simple, effective solution. This is a direct-fit replacement FPCM, part number 15213110, that comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This isn’t just a convenience—it’s a necessity. Without the correct software flashed to the module, your vehicle’s main computer (ECM) cannot communicate with it properly, leading to persistent drivability problems or a no-start condition right out of the box. We handle the programming for you, loading the latest GM software updates to ensure optimal performance and longevity. All you have to do is install it.
From the Diagnostic Bay: The Tahoe That Wouldn’t Quit Stalling
A customer brought in a 2008 Chevy Tahoe that was driving him crazy. It would stall intermittently, sometimes at a stoplight, sometimes on the highway. He had already paid another shop to replace the in-tank fuel pump, but the problem persisted. When I hooked up my scanner, I found a U0109 code—Lost Communication With Fuel Pump Control Module. I went straight to the FPCM, mounted on the driver-side frame rail. These modules are notorious for failing due to their exposure to water, salt, and road debris, causing corrosion and internal shorts. After installing a new, VIN-programmed module, the Tahoe ran perfectly. It was a 20-minute fix that solved a month-long headache for the owner.
Common Signs of a Failing FPCM
- ✔ Vehicle cranks but won’t start
- ✔ Engine stalls unexpectedly while driving or at idle
- ✔ Loss of power or hesitation during acceleration
- ✔ Noticeable decrease in fuel economy
- ✔ Check Engine Light with codes like P069E, U0109, P0230, or P025A
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle in their own driveway. The location varies slightly by model, but it’s typically mounted to the vehicle’s frame or crossmember.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the old FPCM. On most GM trucks and SUVs (like the Tahoe, Silverado, Enclave), it’s on the driver-side frame rail, near the spare tire. On others, it may be on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connector(s). Then, remove the bolts or nuts holding the module to the frame.
- Install the New Module: Bolt the new, pre-programmed module into place. Be sure to clean the mounting surface to ensure a good ground connection.
- Reconnect and Test: Plug the electrical connector(s) into the new FPCM. Reconnect the negative battery terminal. Turn the key to the ‘On’ position for a few seconds to prime the system before starting the engine.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is required so we can program the module with the exact software calibration for your vehicle’s specific systems. This ensures perfect compatibility and prevents communication errors that cause drivability problems.
Is this part difficult to install?
Not at all. For most DIYers with basic hand tools, this is a straightforward replacement. The module is typically mounted on the vehicle’s frame and is easily accessible once you’re under the vehicle.
What happens if I install a module that isn’t programmed?
An unprogrammed module will not work. Your vehicle will likely not start, and you will see a Check Engine Light. Our pre-programming service saves you a trip to the dealership and the high cost of their programming service.
Is this a new part?
Yes, this is a quality replacement part that is tested and then programmed with the latest stable software from GM before being shipped to you.
How do I find the FPCM on my vehicle?
On most GM trucks and full-size SUVs from this era, it’s mounted to the inside of the driver-side frame rail, often above the spare tire. On crossovers like the Traverse or Enclave, it’s frequently on the rear subframe crossmember.
