Restore Your Enclave’s Reliability and Performance
Is your 2010-2012 Buick Enclave experiencing frustrating issues like stalling, hesitation during acceleration, or a dreaded no-start condition? Before you consider replacing the entire fuel pump, the problem often lies with a failing Fuel System Control Module (FSCM). As a technician with over two decades of experience, I’ve seen countless vehicle owners and even other shops misdiagnose these symptoms. This module is the brain behind your fuel pump, and when it fails, it can mimic a bad pump, leading to wasted time and money. This replacement 2010-2012 Enclave Fuel Module is the definitive solution to restore your vehicle’s fuel delivery system to factory specifications.
What makes this part the smart choice is that it arrives at your door completely programmed and ready for installation. We take your vehicle’s VIN and flash the module with the latest, most stable software updates directly from GM. This eliminates the need for an expensive trip to the dealership for programming, saving you hundreds of dollars and significant hassle. It’s a true plug-and-play solution designed for both professional mechanics and determined DIYers.
Case Study: A Tricky Diagnosis
I remember a 2011 Acadia—which shares its platform with the Enclave—that was towed into my bay. The customer had already spent a weekend replacing the in-tank fuel pump, but the engine would still crank and never start. His scanner showed a U0109 (Lost Communication with Fuel Pump Control Module) and a P069E (Fuel Pump Control Module Requested MIL Illumination) code. Instead of just throwing more parts at it, we checked for power at the FSCM connector. The module had power going in, but nothing coming out to the pump. The original FSCM, exposed to years of road salt and moisture on the rear crossmember, had failed internally. A pre-programmed module like this one would have been the correct fix from the start, saving him an entire weekend and the cost of a new pump he didn’t need.
Is Your Enclave Showing These Symptoms?
- âś” Engine cranks but will not start.
- âś” Stalling or sputtering, especially under load or when coming to a stop.
- âś” Hesitation or lack of power during acceleration.
- âś” Reduced fuel economy and poor engine performance.
- âś” Check Engine Light is on with codes like P069E, P0230, or U0109.
- âś” A buzzing or whining noise from the fuel pump that is inconsistent.
A Straightforward Guide to Installation
- âś” Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- âś” Locate the Module: On the 2010-2012 Enclave, the FSCM is typically mounted on the rear crossmember, near the fuel tank. You may need to safely lift and support the vehicle for access.
- âś” Disconnect Electrical Connectors: Carefully press the release tabs on the electrical connectors and pull them straight off the module. Inspect them for any corrosion or damage.
- âś” Remove the Old Module: Unbolt the old FSCM from the frame or crossmember. Note the orientation of the module before removing it.
- âś” Install the New Module: Mount your new, pre-programmed FSCM in the same location and orientation. Secure the mounting bolts.
- âś” Reconnect and Finalize: Plug the electrical connectors firmly into the new module until they click. Reconnect the negative battery terminal. The vehicle is now ready to start with no further programming required.

Frequently Asked Questions
Do I need a scan tool to program this module?
No. This is the biggest benefit of our service. We program the Fuel System Control Module to your vehicle’s specific VIN before we ship it. It arrives ready to install, requiring no additional programming or dealer intervention.
Where is the FSCM located on my 2011 Buick Enclave?
On the Buick Enclave, GMC Acadia, and Chevy Traverse, the FSCM is almost always located on the rear subframe/crossmember, exposed to the elements. This location is a primary reason for its high failure rate due to moisture and corrosion.
What happens if I install this without providing my VIN?
We cannot ship the module until we receive your VIN. The programming is essential for the module to communicate correctly with your vehicle’s other computers, like the ECM and BCM. An unprogrammed module will not work.
Is this the same as a Fuel Pump Driver Module (FPDM)?
Yes, different manufacturers use different names. For these GM vehicles, it’s called a Fuel System Control Module (FSCM), but it performs the same function as what Ford calls a Fuel Pump Driver Module (FPDM)—it regulates the voltage sent to the fuel pump.
Could a bad ground cause the same symptoms?
Absolutely. It’s always wise to check the module’s ground connection to the chassis before ordering a new part. A corroded or loose ground can cause intermittent power and similar running issues. In my experience, however, internal module failure is far more common on these vehicles.
