Is Your GM Vehicle Stalling, Hesitating, or Refusing to Start?
A faulty Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM), is a very common issue on many 2007-2009 GM trucks and SUVs, including your 2009 Buick Enclave. This critical component is responsible for precisely managing the voltage sent to your fuel pump. When it fails, it can starve your engine of fuel, leading to a host of frustrating and potentially dangerous drivability problems. This isn’t just an inconvenience; it’s a critical failure that can leave you stranded. Symptoms often start intermittently but will inevitably worsen, making a reliable replacement essential.
From the Diagnostic Bay
We had a 2009 Tahoe come in on the hook—it would crank but not start. The owner had already replaced the in-tank fuel pump himself, assuming it was the culprit, but the problem persisted. A quick scan showed a P069E code: ‘Fuel Pump Control Module Commanded OFF.’ Instead of throwing more parts at it, we checked the FPCM, located on the driver-side frame rail. It was heavily corroded from road salt and moisture. We installed a new, VIN-programmed module, and the truck fired right up. It’s a classic case where diagnosing the controller saved the customer from replacing a perfectly good fuel pump a second time.
Common Symptoms of a Failing Fuel Pump Control Module
- ✔ Engine cranks but will not start.
- ✔ Stalling while driving, especially under load.
- ✔ Hesitation or stumbling on acceleration.
- ✔ Reduced engine power and ‘limp mode’ activation.
- ✔ Check Engine Light with codes like P069E, P0230, P025A, or U0109.
- ✔ A whining noise from the fuel pump as it receives erratic voltage.
- ✔ Inconsistent fuel pressure readings on a diagnostic tool.

Frequently Asked Questions
Why does this fuel pump module need to be programmed?
The Fuel Pump Control Module must be programmed with your vehicle’s specific VIN to ensure it can communicate correctly with the other computer systems, like the Engine Control Module (ECM). Without correct programming, the vehicle will not start or run properly, and you will likely set communication error codes.
Is this a plug-and-play installation after I receive it?
Yes! Because we program the module to your VIN before shipping, it is a direct plug-and-play installation. No further programming or dealer visits are required. Simply disconnect the old module and connect this new one.
How do I provide my VIN?
After placing your order, please send us a message with your 17-digit VIN. We cannot ship your part until we receive this information. You can typically find your VIN on your driver’s side door jamb sticker, the corner of your dashboard (viewable through the windshield), or on your vehicle’s registration and insurance documents.
Where is the FPCM located on my 2009 Enclave?
On the 2009 Buick Enclave, as well as the Acadia and Traverse, the FPCM is typically located on the rear crossmember. On trucks and large SUVs like the Tahoe or Sierra, it is most often found on the inside of the driver-side frame rail, near the spare tire.
Will this fix a P069E check engine light code?
A P069E code (‘Fuel Pump Control Module Commanded OFF’) is a very strong indicator that the FPCM has failed. While you should always perform a complete diagnosis, replacing a faulty FPCM is the most common and effective repair for this specific trouble code.
