Restore Your Vehicle’s Performance and Reliability
Is your 2009 Buick Enclave or other GM vehicle experiencing frustrating issues like engine stalling, hesitation during acceleration, a long crank time, or a complete no-start condition? Before you consider replacing the entire fuel pump, the culprit is often a faulty Fuel Pump Control Module (FPCM). As a technician with over 20 years of experience, I’ve seen countless drivers spend hundreds on unnecessary parts when this module was the simple, effective fix. This FPCM, also known as a Fuel System Control Module (FSCM), is the brain behind your fuel delivery, and when it fails, it can bring your vehicle to a standstill.
We solve the biggest hurdle in this repair: programming. This module arrives at your door pre-programmed with the latest GM software updates, specifically matched to your vehicle’s Vehicle Identification Number (VIN). This means you can skip the expensive trip to the dealership for flashing. It’s a direct-fit, plug-and-play solution designed to restore proper fuel pressure and get you back on the road with confidence.
Case Study: A Tricky Diagnosis
A customer brought in a 2009 GMC Acadia with an intermittent stalling problem. They had already replaced the in-tank fuel pump, but the issue persisted. The scanner showed code P069E – Fuel Pump Control Module Commanded OFF. Instead of guessing, we hooked up a scope to the FPCM. We found the module was erratically cutting power to the pump, especially under load. This is a classic failure mode. We installed a VIN-programmed 2009 Enclave Fuel Pump Control Module (the same part fits the Acadia), and the fuel pressure stabilized immediately. The customer saved the cost of a second, incorrect repair and drove away with a permanently fixed vehicle.
Common Signs of a Failing FPCM
- ✔ Check Engine Light with codes like P069E, P0230, or U0109 (Lost Communication with FPCM).
- ✔ Engine cranks but will not start.
- ✔ Vehicle stalls unexpectedly, especially when warm or under load.
- ✔ Noticeable loss of engine power and poor acceleration.
- ✔ Rough or unstable idle.
- ✔ A loud whining noise from the fuel pump as it’s being overworked or underpowered.
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle in their own driveway. On the 2009 Enclave, you’ll typically find it mounted to the rear crossmember. Always consult a service manual for the exact location on your specific model.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FPCM. On many of the listed SUVs and trucks, it’s mounted on the driver-side frame rail or a rear crossmember, exposed to the elements.
- Disconnect and Remove: Carefully unplug the electrical connectors. Use a small screwdriver to gently release the locking tabs if they are stuck. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed FPCM into place. Ensure it is securely fastened.
- Reconnect: Plug the electrical connectors firmly into the new module. You should hear a click as they lock in.
- Final Step: Reconnect the negative battery terminal. Start the vehicle to confirm the repair is successful. The engine should start and run smoothly.

Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN is essential for us to program the module with the correct, vehicle-specific software from GM. This ensures perfect compatibility and function without requiring a trip to the dealer, making it a true plug-and-play part.
Is this part difficult to install?
No, for most DIYers with basic tools, this is a straightforward repair. The module is typically mounted to the vehicle’s frame or a crossmember and is accessible from underneath. The most important part is ensuring the electrical connectors are securely fastened.
What happens if I don’t replace a failing FPCM?
Ignoring a failing FPCM can lead to more severe problems, including leaving you stranded with a no-start condition. It can also cause the new in-tank fuel pump to fail prematurely due to incorrect voltage and commands.
Will this fix a P069E code?
Yes, the Diagnostic Trouble Code P069E is one of the most common indicators of a failed Fuel Pump Control Module. Replacing it with this pre-programmed unit is the correct and reliable fix for that code.
