Fix Stalling & No-Start Issues with a VIN-Programmed Fuel Module
If your 2009 Buick Enclave, or another compatible GM vehicle, is experiencing frustrating issues like stalling, hesitation on acceleration, or a complete no-start condition, a failing Fuel Pump Control Module (FPCM) is a very common cause. This isn’t just an inconvenience; it’s a reliability issue that can leave you stranded. This module, also known as a Fuel System Control Module (FSCM), is the brain behind your fuel pump, regulating voltage to ensure precise fuel pressure. When it fails, your engine is starved of the fuel it needs to run properly.
We offer a dependable and straightforward solution. This is a direct-replacement 2009 Enclave Fuel Pump Module that comes fully programmed with the latest GM software updates specifically for your vehicle’s Vehicle Identification Number (VIN). This critical step means you can skip the expensive trip to the dealership for programming. It arrives at your door ready for installation, making it a true plug-and-play fix for both professional technicians and DIY enthusiasts.
Case Study: A Tricky Diagnosis
I had a 2008 Chevy Tahoe in my bay that was a real head-scratcher for its owner. The truck would run fine for days, then suddenly stall at a stoplight and refuse to restart for 20 minutes. The owner had already replaced the in-tank fuel pump, but the problem persisted. When I hooked up my diagnostic scanner, I saw DTC P069E (Fuel Pump Control Module Commanded On) stored in memory. Instead of just throwing parts at it, I monitored the FPCM’s commanded fuel pressure versus the actual pressure reading from the fuel rail sensor. The commanded pressure was steady, but the actual pressure would erratically drop to zero right before a stall. This told me the PCM was doing its job, but the FPCM wasn’t executing the command. We installed a new, pre-programmed module, and the Tahoe has run flawlessly ever since. It’s a classic example of how this small module can cause major headaches.
Is Your Vehicle Showing These Symptoms?
A failing FPCM can manifest in several ways. If you’re experiencing any of the following, this module is the likely solution:
- âś” Engine cranks but will not start
- âś” Stalling, especially when coming to a stop or under load
- âś” Severe hesitation or sputtering during acceleration
- âś” Reduced engine power and poor fuel economy
- âś” An illuminated Check Engine Light with specific trouble codes
- âś” Common Diagnostic Trouble Codes (DTCs): P069E, P0230, P025A, U0109 (Lost Communication with FPCM)
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle with basic tools. The module is typically located on the vehicle’s frame rail or crossmember, away from excessive heat. Our pre-programmed module makes the process simple.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the old FPCM. On most GM trucks and SUVs like the Tahoe or Sierra, it’s mounted to the driver-side frame rail, near the spare tire. On vehicles like the Enclave or Traverse, check the rear crossmember.
- Disconnect and Remove: Unplug the electrical connectors. Be gentle with the locking tabs. Then, unbolt the module from the frame.
- Install the New Module: Bolt the new, pre-programmed module into the same location. Ensure it is securely mounted.
- Reconnect: Firmly plug in the electrical connectors until they click into place.
- Final Step: Reconnect the negative battery terminal. Start the vehicle to verify the repair.

Frequently Asked Questions
Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and it will arrive ready to install with the latest GM software.
How do I provide my VIN?
You can add your 17-digit VIN in the notes section at checkout or send it to us in a message after you place your order. We cannot ship the module until we receive your VIN.
What is the difference between the fuel pump and the fuel pump control module?
The fuel pump is a motor located in your fuel tank that physically pumps fuel. The FPCM is a small computer that tells the fuel pump how fast to run to maintain correct fuel pressure, making it a critical part of the fuel delivery system.
Where is this part located on my vehicle?
On most GM trucks and large SUVs, it’s mounted on the driver-side frame rail near the spare tire. On crossover SUVs like the Enclave, Acadia, and Traverse, it’s typically on the rear subframe or crossmember.
My old part has a different number on it. Will this still work?
Yes, this part is a compatible replacement for multiple part numbers, including 13501024, 20759945, 25866052, and others listed above. As long as your vehicle is on the compatibility list, this module will work correctly.
