Is Your 2010-2012 Buick Enclave Stalling, Cranking with No Start, or Showing a Check Engine Light?
As a technician with over two decades of experience, I’ve seen this scenario countless times. Your Enclave suddenly refuses to start, or it stalls unexpectedly in traffic, leaving you stranded. When you scan it, you likely find trouble code P069E or U0109 (Lost Communication With Fuel Pump Control Module). The issue isn’t always the fuel pump itself; more often than not, it’s the brain that controls it: the Fuel System Control Module (FSCM).
This module is the critical link between your vehicle’s main computer (ECM) and the fuel pump. It regulates the voltage sent to the pump, ensuring precise fuel pressure for optimal performance and efficiency. When it fails, your fuel delivery becomes erratic, leading to the frustrating and potentially dangerous symptoms you’re experiencing.

Expert Pro Tip: Check Your Connectors
Before installing your new FSCM, take 30 seconds to inspect the wiring harness connector. On the Enclave, the module is located on the rear crossmember, exposed to road salt and moisture. I’ve seen many repairs fail prematurely because of corrosion on the connector pins. A quick spray with an electronics-safe contact cleaner and a visual check for any green or white powder can prevent intermittent communication issues and ensure a solid, long-lasting repair.
Plug-and-Play Installation: Get Back on the Road Fast
Replacing the FSCM on your Buick Enclave is a straightforward job that a confident DIYer can handle. You’ll find the module mounted to the rear crossmember, typically near the fuel tank.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Access the Module: Safely raise and support the rear of the vehicle to gain access to the underside.
- Locate the FSCM: Find the module mounted on the rear crossmember. It will be a small, black box with electrical connectors.
- Disconnect and Remove: Carefully unclip the electrical connectors. Then, remove the bolts or nuts securing the old module to the frame.
- Install the New Module: Mount your new, pre-programmed FSCM in the exact same location and secure it with the original hardware.
- Reconnect: Firmly plug the electrical connectors into the new module until they click into place.
