Restore Peak Performance and Reliability to Your GM Vehicle
Is your 2010-2012 Buick Enclave, or another compatible GM vehicle, suddenly stalling, hesitating, or refusing to start? Are you staring at a frustrating Check Engine Light with codes like P069E or P0230? Before you consider replacing the entire fuel pump, the issue is often a faulty Fuel System Control Module (FSCM). I’ve seen this exact scenario play out countless times on my service floor. This module is the brain behind your fuel pump, and when it fails, it starves your engine of the fuel it needs. This isn’t just an inconvenience; it can be a serious safety issue if your vehicle stalls in traffic.
We offer a simple, permanent solution. This genuine OEM-spec Fuel System Control Module arrives at your door fully programmed with the latest GM software updates. We handle the complex part—the programming—so you don’t have to. Simply provide your vehicle’s VIN at checkout, and our experts will flash the module specifically for your car or truck. This eliminates the need for an expensive trip to the dealership, saving you time, money, and the headache of scheduling appointments. This is the direct-fit, plug-and-play fix you’ve been looking for to get your vehicle running smoothly and reliably again.
Case Study: A Tricky Diagnosis
A customer brought in their 2011 Buick Enclave with a classic complaint: intermittent stalling at low speeds and an occasional no-start. They had already replaced the fuel pump based on a friend’s advice, but the problem persisted. After hooking up my scanner, I saw code P069E (Fuel Pump Control Module Commanded OFF). Instead of just throwing parts at it, we tested the FSCM’s output. Sure enough, it was erratic. We installed one of our pre-programmed modules, and the Enclave fired right up and ran perfectly. The customer saved hundreds by avoiding a second, unnecessary fuel pump job and got a reliable fix that addressed the root cause.
Is Your Vehicle Showing These Symptoms?
A failing FSCM can mimic a bad fuel pump. If you’re experiencing any of the following, this module is the likely culprit:
- ✔ Engine cranks but won’t start
- ✔ Stalling, especially during acceleration or at idle
- ✔ Rough or unstable idle
- ✔ Loss of power and poor acceleration
- ✔ Check Engine Light active with DTCs P069E, P0230, or U0109
- ✔ Reduced fuel economy
A Straightforward Guide to Installation
Replacing the 2010-2012 Enclave Fuel System Control Module is a job most DIYers can handle with basic tools. On the Enclave, Acadia, and Traverse, it’s typically located on the rear crossmember, making it accessible without dropping the fuel tank.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FSCM mounted to the vehicle’s frame or crossmember. On trucks, it’s often on the driver-side frame rail. On the Enclave, check the rear crossmember area.
- Disconnect Electrical Connectors: Carefully press the release tabs and unplug the electrical connectors from the old module. Inspect them for any corrosion or damage.
- Remove Old Module: Unbolt the old FSCM from its mounting bracket. It’s typically held on by two or three small bolts.
- Install New Module: Bolt your new, pre-programmed FSCM into place. Ensure it is securely fastened.
- Reconnect Everything: Plug the electrical connectors firmly into the new module. Reconnect the negative battery terminal.
- Final Check: Start the vehicle. It should now run smoothly without the previous issues. The Check Engine Light may clear on its own after a few drive cycles, or you can clear it with a standard OBD-II scanner.
