Restore Your Enclave’s Performance and Reliability
If your 2013-2014 Buick Enclave is experiencing frustrating issues like engine stalling, hesitation during acceleration, or a dreaded no-start condition, a failing Fuel Pump Control Module (FPCM) is a very common culprit. As a technician with over two decades of experience, I’ve seen this exact problem countless times. The FPCM, also known as a Fuel System Control Module (FSCM), is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to unreliable and potentially unsafe performance.
Don’t just replace the fuel pump and hope for the best. This is a direct-fit, VIN-programmed 2013-2014 Enclave Fuel Pump Module that solves the root cause. We take the guesswork out of the repair by flashing the module with the latest GM software specific to your vehicle’s VIN before we ship it. This means no expensive trips to the dealership for programming—it’s a true plug-and-play solution you can install yourself.
From the Diagnostic Bay: The Overlooked Culprit
I remember a 2013 Traverse (which shares its platform with the Enclave) that came into my shop. The owner had already replaced the in-tank fuel pump twice, but the intermittent stalling persisted. He was frustrated and out of money. A quick scan showed a U0109 code (Lost Communication With Fuel Pump Control Module). I put the vehicle on the lift and went straight to the FPCM on the rear crossmember. Just as I suspected, the module’s casing was swollen and the connectors were green with corrosion from years of exposure to road salt and water. A new, programmed module fixed the issue in 20 minutes. It’s a classic case of diagnosing the whole system, not just the loudest part.
Is Your Buick Showing These Symptoms?
A failing FPCM can mimic a bad fuel pump. Watch for these specific warning signs before you spend money on the wrong part. This module is the solution for:
- âś” Engine stalling, especially when warm or under load
- âś” Extended cranking time before the engine starts
- âś” Hesitation or stumbling on acceleration
- âś” Reduced engine power and poor fuel economy
- âś” An active Check Engine Light with codes such as P069E, U0109, or P0230
A Straightforward Guide to Installation
Installing your new 2013-2014 Enclave Fuel Pump Module is a job most DIYers can handle with basic tools. On the Enclave, the module is typically located on the rear subframe crossmember, making it accessible without dropping the fuel tank.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Safely raise the rear of the vehicle and locate the FPCM mounted to the rear crossmember, just ahead of the rear differential.
- Disconnect Connectors: Carefully press the release tabs and disconnect the two electrical connectors from the old module. Inspect the harness connectors for any corrosion and clean if necessary.
- Remove the Old Module: Using a socket wrench, remove the bolts securing the old module to the crossmember.
- Install the New Module: Mount your new, pre-programmed module in the same location and secure it with the original bolts.
- Final Connections: Plug the electrical connectors firmly into the new module until they click. Reconnect the negative battery terminal.
- Cycle the Key: Turn the ignition to the ‘On’ position (without starting) for 10 seconds to allow the system to prime. Start the vehicle and check for proper operation.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN allows us to program the module with the exact software and calibrations from GM for your specific engine, transmission, and options. This ensures perfect communication and flawless performance, just like a part from the dealer, but without the extra cost and hassle.
Is this part difficult to install on my 2014 Enclave?
No, it’s one of the more straightforward module replacements. On the Enclave, it’s mounted on the rear crossmember, which is accessible from underneath the vehicle. With basic hand tools, most DIYers can complete the job in under an hour.
Will this fix a P069E check engine light code?
Yes, in the vast majority of cases, a faulty FPCM is the direct cause of a P069E code (Fuel Pump Control Module Requested MIL Illumination). Replacing the module with this pre-programmed unit is the correct fix for that specific diagnostic trouble code.
What is the difference between an FPCM and an FSCM?
There is no functional difference. FPCM (Fuel Pump Control Module) and FSCM (Fuel System Control Module) are two different names for the same part. GM service information often uses the terms interchangeably.
Is this a new or used part?
This is a high-quality, tested, and verified used component that has been professionally programmed with the latest software for your vehicle, ensuring reliable operation and a perfect fit.
