Is your GMC Acadia or other GM vehicle suddenly stalling, hesitating, or refusing to start? Before you condemn the expensive in-tank fuel pump, the real culprit is often the Fuel Pump Control Module (FPCM). As a technician with over two decades of experience, I’ve seen this exact scenario play out hundreds of times. This module, often exposed to the elements on the frame rail, is a common failure point that can leave you stranded. This listing is for a direct-replacement FPCM, delivered to your door fully programmed with the latest GM software specifically for your vehicle.
We take the guesswork and extra cost out of the repair. Simply provide your Vehicle Identification Number (VIN) during checkout, and our experts will flash the module before it ships. This means no extra trip to the dealership and no need for expensive diagnostic tools for programming. You get a part that is truly plug-and-play, designed to restore proper fuel pressure and get your vehicle running reliably again.
From the Diagnostic Bay: The $800 Misdiagnosis
A customer brought in their 2008 Silverado with a classic complaint: it would crank but not start, and sometimes it would die while driving. Another shop had quoted them nearly $800 to replace the in-tank fuel pump. I scanned the truck and found code U0109 – Lost Communication with Fuel Pump Control Module. Instead of jumping to the pump, I located the FPCM on the driver-side frame rail. It was covered in corrosion from years of road salt and moisture. A quick test confirmed the module was dead. We installed a new, programmed FPCM, and the truck fired right up. The customer saved over $600 by correctly diagnosing the issue. This is why checking the FPCM first is critical on these vehicles.
Is Your Vehicle Showing These Symptoms?
A failing FPCM can mimic a bad fuel pump. Watch for these common warning signs:
- âś” Engine cranks but will not start
- âś” Stalling, especially under load or when coming to a stop
- âś” Hesitation or stumbling during acceleration
- âś” Reduced engine power and poor fuel economy
- âś” Check Engine Light with codes like U0109, P0230, or P025A
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle in their driveway. While the exact location varies, the process is generally the same.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs (Silverado, Tahoe, Escalade), it’s on the driver-side frame rail. On vehicles like the Acadia or Traverse, it’s often on a rear crossmember. For the VUE, check the passenger-side rear of the engine compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, unbolt the module from its mounting location. These bolts can sometimes be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed module into place. Reconnect the electrical connectors, ensuring they click securely.
- Final Step: Reconnect the negative battery terminal. The vehicle is now ready to start with no further programming required.

Frequently Asked Questions
What does the Fuel Pump Control Module do?
The FPCM, or Fuel Pump Driver Module, regulates the voltage sent to the electric fuel pump. Instead of running the pump at full speed all the time, this module varies the pump’s speed based on the engine’s demand for fuel. This improves efficiency and extends the life of the fuel pump.
Why do you need my VIN?
Your vehicle’s VIN is required so we can program the module with the correct, vehicle-specific software from GM. This ensures it communicates properly with your vehicle’s computer (ECM) and controls the fuel pump as the factory intended. Without this step, the part will not work.
Is this part difficult to install?
For most individuals with basic mechanical skills, this is a straightforward repair. It typically involves removing a few bolts and unplugging connectors. Since our module comes pre-programmed, there is no complex computer work needed on your end, making it a simple plug-and-play process.
Are there any other parts I should check?
Before replacing the module, it’s always a good idea to check the associated fuse in your vehicle’s fuse box and inspect the wiring harness connected to the FPCM for any obvious damage or corrosion. However, in most cases, the module itself is the point of failure.
What if I have a different part number on my old module?
This module replaces a long list of previous GM part numbers. The compatible numbers include 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. If your module has one of these numbers, this part is the correct replacement.
