Is Your 2010-2012 Buick Enclave Stalling or Refusing to Start?
As a technician with over two decades of experience, one of the most common issues I see on these GM platforms is a sudden no-start or stalling condition that leaves owners stranded. Just last month, a 2011 Enclave was towed to my shop. It would crank perfectly but wouldn’t fire up. The owner had already replaced the fuel pump, thinking that was the obvious culprit, but the problem persisted. A quick scan revealed the tell-tale trouble code: P069E – Fuel Pump Control Module Requested MIL Illumination. The real issue wasn’t the pump; it was the brain telling it what to doโthe Fuel System Control Module (FSCM).
This FSCM, also known as a fuel pump driver module, is the direct solution to this frustrating and widespread problem. It’s not just a part; it’s a complete, ready-to-install fix that saves you a trip to the dealership and the high cost of programming.
The Plug-and-Play Advantage: Programmed Specifically for Your Enclave
The biggest headache with replacing modern vehicle electronics is the need for expensive, dealer-level programming. We eliminate that completely. Before we ship this module, we use your vehicle’s VIN to flash it with the latest, most stable software directly from GM. This ensures perfect communication with your Enclave’s other computers, like the ECM and BCM, right out of the box. This isn’t a generic part; it’s prepared for your specific vehicle.
Common Symptoms of a Failing FSCM:
- โ Engine cranks but will not start
- โ Vehicle stalls while driving, sometimes intermittently
- โ Check Engine Light with code P069E, P0230, or other fuel-related codes
- โ Reduced engine power or hesitation during acceleration
- โ Inconsistent fuel pressure readings
Expert Pro Tip from a 20-Year Technician
Before you install your new FSCM, take a moment to closely inspect the electrical connector harness. These modules are often mounted on the frame or crossmember, exposed to moisture and road salt. I’ve seen countless cases where corrosion on the connector pins was the root cause of the failure. Cleaning the connector with a dedicated contact cleaner and a small brush can prevent damage to your new module and ensure a solid, long-lasting repair.
Easy Installation on Your 2010-2012 Enclave FSCM
You don’t need to be a master mechanic to replace this part. For the Buick Enclave, GMC Acadia, and Chevy Traverse, the module is typically located on the rear subframe/crossmember, making it accessible with basic hand tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FSCM mounted to the rear crossmember, near the fuel tank.
- Disconnect: Carefully unplug the electrical harness connector(s) from the old module.
- Remove Old Part: Unbolt the old FSCM from its mounting location.
- Install New Part: Bolt your new, pre-programmed FSCM into place.
- Reconnect: Securely plug the electrical connector(s) into the new module. You should hear a click.
- Power Up: Reconnect the negative battery terminal.
- Start the Engine: Your Enclave should now start and run smoothly, with the Check Engine Light off.
