Restore Your Vehicle’s Performance and End Frustrating Fuel Issues
Is your 2013-2014 Buick Enclave or other GM vehicle experiencing sudden stalling, extended cranking times, or a loss of power? Before you condemn the fuel pump, the culprit is often its electronic controller. As a technician with over two decades of experience, I’ve seen countless drivers spend a fortune on a new fuel pump only to discover the real problem was a faulty Fuel Pump Control Module (FPCM). This module is the brain of your fuel delivery system, and when it fails, it can leave you stranded without warning.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine OEM-quality module and professionally program it with the latest GM software updates specifically for your vehicle’s VIN. This critical step ensures perfect communication with your car’s computer, restoring original performance and efficiency. By providing your VIN at checkout, you eliminate the need for an expensive trip to the dealership for programming, saving you both time and money.
From the Diagnostic Bay: The Intermittent Stall Case
I remember a 2013 GMC Acadia (which shares its platform with the Enclave) that came into my shop with a maddeningly intermittent problem. The owner complained it would run perfectly for days, then suddenly lose power and stall at a stoplight. No check engine light was on, but stored history codes pointed to U0109 (Lost Communication with Fuel Pump Control Module) and P069E (Fuel Pump Control Module Requested MIL Illumination). Instead of jumping to the most expensive part—the in-tank fuel pump—we checked the FPCM located on the rear crossmember. We found corrosion on the connector pins from road salt and moisture. Replacing it with a pre-programmed 2013-2014 Enclave Fuel Pump Module like this one solved the problem permanently. It’s a classic example of how diagnosing the controller first can save hundreds in unnecessary repairs.
Is Your Vehicle Showing These Fuel System Symptoms?
A failing FPCM can mimic a bad fuel pump. Watch for these common warning signs before making a costly misdiagnosis. A faulty module is often the root cause.
- ✔ Engine cranks but refuses to start.
- ✔ Vehicle starts but stalls moments later, especially under load.
- ✔ Noticeable loss of engine power and poor acceleration.
- ✔ A “Service Fuel System” message appears on your driver information center.
- ✔ Stored Diagnostic Trouble Codes (DTCs) such as P069E, U0109, P0230, or P025A.
- ✔ Inconsistent fuel pressure readings during diagnostic checks.
A Straightforward Guide to Installation
Installing your new 2013-2014 Enclave Fuel Pump Module is a manageable job for a confident DIYer. Since it arrives pre-programmed, no special electronic tools are needed.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Module: On the Enclave, Traverse, and Acadia, the FPCM is typically mounted on the rear subframe/crossmember, near the fuel tank. On trucks and SUVs like the Tahoe or Yukon, it’s often on the driver’s side frame rail.
- Disconnect and Remove: Carefully unplug the electrical connector. Inspect the harness side for any corrosion and clean if necessary. Then, unbolt the old module from its mounting location.
- Install the New Module: Bolt the new, pre-programmed module securely in place. Reconnect the electrical harness, ensuring it clicks firmly into position.
- Final Steps: Reconnect the negative battery terminal. The vehicle may require a few key cycles (turning the key to ‘On’ for 10 seconds, then ‘Off’) to re-initialize all systems before starting the engine.

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 it works perfectly with your engine and other electronics, preventing compatibility issues and saving you a trip to the dealer.
Is this part difficult to install?
For most DIY mechanics with basic tools, this is a straightforward replacement. The module is typically mounted on the vehicle’s frame or subframe with a few bolts. Since it comes pre-programmed, no computer or special tools are needed for the installation.
What is the difference between an FPCM and a fuel pump?
The fuel pump is a mechanical device inside the fuel tank that moves gasoline. The Fuel Pump Control Module (FPCM) is the electronic ‘brain’ that tells the pump how fast to run based on engine demand. The FPCM often fails before the pump itself.
Will this fix a P069E code?
Yes, a P069E trouble code is one of the most common indicators of a failing FPCM. Replacing the module with this pre-programmed unit is the correct and reliable fix for that specific code.
Is this compatible with part number 20964304?
Yes, this module, part number 20964305, is a fully compatible and updated replacement for the earlier part number 20964304.
