Are you battling frustrating fuel delivery issues with your 2009 Buick Enclave or another GM vehicle? If you’re experiencing symptoms like engine stalling, hesitation on acceleration, a persistent Check Engine Light, or a dreaded no-start condition, the problem might not be your fuel pump. In my 20+ years of diagnostics, I’ve seen countless vehicle owners and even other shops mistakenly replace the fuel pump, only to have the same issues return. The real culprit is often a failed Fuel Pump Control Module (FPCM).
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the repair by pre-programming this module to your vehicle’s specific VIN with the latest GM software updates. This means you can skip the trip to the dealership and avoid their costly programming fees. This is the definitive fix that restores proper communication between your vehicle’s computer and the fuel pump, ensuring reliable performance and peace of mind.
A Technician’s Notebook: The Misdiagnosed Fuel Pump
A customer brought in a 2008 Chevy Tahoe that was on its second new fuel pump in six months, yet it still stalled randomly at red lights. The fuel pressure would test fine one minute and drop to zero the next. Instead of throwing a third pump at it, we looked upstream. We found the FPCM, mounted on the frame rail, was corroded from years of exposure to road salt and moisture. The module was intermittently failing to command the pump. We installed a new, pre-programmed FPCM, and the problem was solved for good. It’s a classic case where checking the FPCM first saved hundreds of dollars and immense frustration.
Is Your GM Vehicle Showing These Symptoms?
A failing FPCM can manifest in several ways that are often mistaken for a bad fuel pump. Before you spend time and money on a more complex repair, check if you’re experiencing any of the following:
- âś” Engine cranks but won’t start
- âś” Vehicle stalls unexpectedly while driving or at idle
- âś” Noticeable hesitation or sputtering during acceleration
- âś” Reduced engine power and poor fuel economy
- âś” Check Engine Light is on with codes like P069E, P0230, or U0109
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIY enthusiasts can handle with basic tools. Because this module comes pre-programmed, no special electronic equipment is needed.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Module: On most trucks and SUVs like the Tahoe or Sierra, the FPCM is mounted on the driver’s side frame rail, near the spare tire. On other vehicles like the Enclave or Traverse, it’s often on a rear crossmember. Consult a repair manual for your specific vehicle if you’re unsure.
- Disconnect and Remove: Carefully unplug the electrical connector(s). Then, remove the bolts or nuts securing the old module to the frame. It may be corroded, so some penetrating oil can be helpful.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Ensure the electrical connector is clean and free of debris before plugging it in securely. You should hear a ‘click’.
- Final Steps: Reconnect the negative battery terminal. The vehicle is now ready to start. The system will perform a self-check, and your fuel delivery issues should be resolved.

Frequently Asked Questions
Frequently Asked Questions
What exactly does a Fuel Pump Control Module do?
The FPCM acts as a smart controller for your fuel pump. Instead of the pump running at full speed all the time, the FPCM receives commands from the Engine Control Module (ECM) and adjusts the voltage to the pump. This provides precise fuel pressure based on engine load, which improves efficiency and prolongs the life of the fuel pump.
Why is VIN programming so important for this part?
The FPCM must be calibrated to your vehicle’s specific operating parameters and security system. Without correct VIN programming, the module won’t communicate properly with the ECM, leading to a no-start condition or a persistent Check Engine Light. Our service handles this for you, so it’s ready to install out of the box.
What do I need to do after I place my order?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit Vehicle Identification Number (VIN). Our technicians will use this to program the module with the latest GM software before we ship it to you.
Will this fix a P069E trouble code?
Yes, DTC P069E (Fuel Pump Control Module Requested MIL Illumination) is one of the most common codes indicating a faulty FPCM. Replacing the module with this pre-programmed unit is the correct repair for this code, assuming the wiring and connectors are in good condition.
Is this a difficult part to replace for a DIYer?
For most of the listed vehicles, this is a very manageable DIY job. It typically involves removing a few bolts and unplugging a connector. Since our module is pre-programmed, you eliminate the most difficult part of the job—the electronic setup.
