Restore Your Buick’s Performance and Reliability
Is your 2010-2012 Buick Enclave experiencing frustrating and potentially dangerous issues like stalling, hesitating during acceleration, or refusing to start altogether? These are classic signs of a failing Fuel System Control Module (FSCM). This critical component is the brain behind your fuel pump, regulating fuel pressure and delivery to the engine. When it fails, it can leave you stranded. In my 20+ years of automotive diagnostics, I’ve seen countless vehicles where a faulty FSCM was the hidden culprit behind what seemed like a bad fuel pump.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra cost out of the repair by pre-programming this module to your vehicle’s specific VIN with the latest GM software updates. This means you can skip the expensive trip to the dealership for programming. You get a reliable part that communicates flawlessly with your vehicle’s computer system right out of the box, ensuring your engine runs smoothly and efficiently. This 2010-2012 Enclave Fuel Module is the definitive fix for restoring your vehicle’s proper fuel system operation.
Case Study: A Tricky Diagnosis
I remember a 2011 GMC Acadia—which shares its platform and FSCM location with the Enclave—that came into the shop with an intermittent no-start condition. The owner had already replaced the fuel pump, but the problem persisted. The scan tool showed a U0109 code (Lost Communication with Fuel Pump Control Module). Instead of just looking at the code, I went straight to the module’s location on the rear crossmember. As expected, years of exposure to road salt and moisture had corroded the connector pins and compromised the module’s internal circuits. A simple part swap with a pre-programmed module like this one had the vehicle running reliably in under 30 minutes. It’s a textbook example of why checking the FSCM is a crucial diagnostic step.
Common Signs of a Failing FSCM
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly, especially under load
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light (CEL) illuminated with specific codes
- ✔ Common Diagnostic Trouble Codes (DTCs): P069E, U0109, P0230, P0606
A Straightforward Guide to Installation
Replacing the 2010-2012 Enclave Fuel Module is a job most DIYers can handle with basic tools. On the Enclave, Acadia, and Traverse, it’s typically mounted on the rear subframe/crossmember.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Safely raise the rear of the vehicle and secure it on jack stands. The FSCM is a small, black box mounted to the rear crossmember, often near the spare tire area.
- Disconnect and Remove: Carefully unplug the electrical connector(s). Be gentle to avoid breaking the locking tabs. Then, remove the bolts or nuts holding the module to the frame.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location and secure it with the original hardware.
- Reconnect: Firmly plug in the electrical connector until it clicks into place. Reconnect the negative battery terminal.
- Final Check: Start the vehicle. It may take a few extra seconds of cranking to prime the fuel system. Your vehicle should now start and run smoothly.
