Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If you’re experiencing erratic engine behavior, a sudden loss of power, or a frustrating no-start condition in your 2009 Buick Enclave or other compatible GM vehicle, a faulty Fuel Pump Control Module (FPCM) is a very likely culprit. This critical component, also known as a Fuel System Control Module (FSCM), is the brain behind your vehicle’s fuel delivery system. It doesn’t just turn the fuel pump on and off; it precisely regulates the voltage sent to the pump, controlling its speed and the resulting fuel pressure. This ensures your engine gets the exact amount of fuel it needs for optimal performance and efficiency under all driving conditions.
The Common Point of Failure
Unfortunately, on many GM trucks and SUVs, these modules are mounted on the frame rail, where they are constantly exposed to water, road salt, dirt, and vibrations. This harsh environment can lead to internal corrosion, failed electronic components, and compromised electrical connections, causing a variety of perplexing symptoms. A failing FPCM can mimic a bad fuel pump, leading to misdiagnosis and costly, unnecessary repairs. Before you consider replacing the in-tank fuel pump, a much more labor-intensive job, a thorough inspection of the FPCM is essential.
From the Diagnostic Bay
I once had a 2008 Silverado 1500 towed in with a classic ‘crank, no start’ complaint. The owner had already replaced the fuel pump himself, a tough job, but the truck still wouldn’t fire up. He was convinced he had a major electrical problem. After plugging in my scanner, I saw the code P069E – ‘Fuel Pump Control Module Commanded OFF.’ Instead of diving into complex wiring diagrams, I went straight to the FPCM on the driver’s side frame rail. The module’s casing was swollen and the connector was green with corrosion. We installed a new, pre-programmed module, cleaned the connector, and the truck started on the first try. The customer could have saved himself a whole weekend of work and the cost of a fuel pump by checking this component first.
Your Plug-and-Play Solution: The Programmed 2009 Enclave Fuel Module
This isn’t just a replacement part; it’s a complete solution. We remove the biggest headache associated with FPCM replacement: the need for expensive dealership programming. Simply provide us with your vehicle’s Vehicle Identification Number (VIN) during checkout, and our technicians will flash this module with the latest, most stable software directly from GM. This ensures perfect communication with your vehicle’s other computers, like the ECM, and corrects potential software glitches that may have existed from the factory. When the part arrives at your door, it’s ready for a straightforward, plug-and-play installation.
Common Symptoms of a Failing FPCM:
- ✔ Engine stalls unexpectedly, especially under load.
- ✔ Vehicle cranks but will not start.
- ✔ Noticeable hesitation or stumbling during acceleration.
- ✔ Reduced engine power and poor performance.
- ✔ Check Engine Light is on with codes like P069E, P0230, P025A, or U0109.
- ✔ A humming or whining noise from the fuel pump that is inconsistent.
- ✔ Rough or unstable idle.

Frequently Asked Questions About the 2009 Enclave Fuel Module
Do I need to take my vehicle to a dealer for programming?
Absolutely not. The main benefit of this part is that we program it for you before it ships. Just provide your VIN when you order, and it will arrive ready to install. This saves you the time, towing costs, and programming fees associated with a dealership visit.
Where is this module located on my vehicle?
On most trucks and large SUVs like the Silverado, Tahoe, and Escalade, the FPCM is mounted to the driver’s side frame rail, near the spare tire. On other models like the Traverse or Acadia, it may be on a rear crossmember. Always consult a service manual for your specific vehicle if you are unsure.
What happens if I forget to provide my VIN?
Programming is essential for this module to function in your vehicle. We cannot ship the part until we receive your VIN. Our customer service team will contact you to get the necessary information if it’s missing from your order.
Will this fix a P069E trouble code?
Yes, the P069E code is one of the most common indicators of a failed Fuel Pump Control Module. While you should always perform a complete diagnosis, replacing a faulty FPCM is the standard and effective repair for this code.
Is installation difficult? Can I do it myself?
For someone with moderate mechanical experience, the installation is straightforward. It typically requires basic hand tools, such as a socket set, to remove a few bolts. The most important steps are to disconnect the vehicle’s battery first and carefully inspect the electrical connector for any corrosion or damage that needs to be cleaned.
