Restore Your Enclave’s Performance and Reliability
Is your 2010-2012 Buick Enclave, or another GM vehicle, suddenly stalling, refusing to start, or showing a ‘Reduced Engine Power’ message? Before you condemn the fuel pump, the real culprit is often the Fuel System Control Module (FSCM). As a technician with over two decades of experience, I’ve seen this exact scenario countless times. This module is the brain that tells the fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to frustrating and unpredictable problems.
We solve this problem by providing a direct-replacement FSCM that is pre-programmed to your vehicle’s specific VIN. You get the latest GM software updates without ever stepping foot in a dealership. This isn’t just a part; it’s a complete, ready-to-install solution that restores proper fuel delivery and gets you back on the road with confidence.
Case Study: A Tricky Diagnosis
A customer brought in a 2011 Chevy Traverse—a vehicle that shares its platform with the Enclave—with a complaint of intermittent stalling at stoplights. They had already spent hundreds replacing the in-tank fuel pump, but the problem persisted. A quick scan revealed DTC P069E (Fuel Pump Control Module Commanded OFF). Instead of guessing, we checked the FSCM, which is mounted on the rear crossmember. We found tell-tale signs of water intrusion and corrosion at the connector. Installing a new, properly programmed FSCM like this one solved the issue in under 30 minutes. The customer was relieved to have a reliable vehicle again and wished they had started with the module first.
Common Signs of a Failing FSCM
- ✔ Engine cranks but will not start.
- ✔ Vehicle starts and then stalls immediately or after a few minutes.
- ✔ Sudden stalling while driving, especially during low-speed maneuvers.
- ✔ ‘Reduced Engine Power’ message illuminated on the dash.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Diagnostic Trouble Codes (DTCs) such as P069E, P0230, or U0109 stored in the computer.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical mishaps.
- ✔ Locate the Module: On the Buick Enclave, Acadia, and Traverse, the FSCM is typically mounted on the rear crossmember, accessible from underneath the vehicle. On trucks and vans, it’s often on the driver-side frame rail.
- ✔ Disconnect and Remove: Carefully unplug the electrical connector(s). Be gentle with the locking tabs, as they can become brittle. Then, remove the bolts or nuts holding the old module to the frame or crossmember.
- ✔ Install the New Module: Mount your new, pre-programmed FSCM in the same location using the original hardware. Ensure it is securely fastened.
- ✔ Reconnect and Finalize: Plug the electrical connector(s) firmly into the new module. Reconnect the negative battery terminal. Start the vehicle to confirm the repair is successful.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential for us to program the module with the exact software and calibrations your vehicle requires from the factory. This ensures perfect communication between the FSCM and your vehicle’s other computers, guaranteeing a seamless, plug-and-play installation.
Is this part difficult to install?
For someone with basic mechanical skills, this is a very manageable job. The module is typically held on by two bolts and has one electrical connector. The most difficult part is safely accessing it underneath the vehicle. Our installation guide above provides the key steps.
Will this fix a P069E code?
Yes, in a vast majority of cases, the DTC P069E is caused by a failing Fuel System Control Module. While other issues like wiring problems can be a cause, a faulty FSCM is the most common culprit I’ve diagnosed in my shop for this specific code.
What if my original part number is different?
This module is a direct replacement for several part numbers, including 20827745, 20877116, and 20850927. GM often consolidates part numbers over time. As long as your vehicle is on our compatibility list, this part will work perfectly.
Is any other learning procedure required after installation?
No. Because we program the module to your VIN before shipping, no further dealership visits or special scan tools are needed. Simply install the part, and you’re ready to go. This is the key benefit of our service.
