Is your 2013 or 2014 GMC Acadia suddenly stalling, hesitating, or refusing to start? As a mechanic with over two decades of experience, I’ve seen these exact symptoms countless times. The culprit is often a failing Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This small but critical component is responsible for managing the voltage sent to your fuel pump, ensuring your engine gets the precise amount of fuel it needs. When it fails, it can leave you stranded and frustrated.
This isn’t just another part off the shelf. This is a complete, reliable solution. We are offering a genuine GM Fuel Pump Control Module, part number 20964304, that comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This crucial step, which we handle before shipping, ensures perfect communication with your vehicle’s computer systems. You get the latest GM software updates without ever stepping foot in a dealership, saving you time and hundreds in programming fees.
A Technician’s Notebook: The Intermittent Stall
A customer brought in their 2014 Acadia with a problem that was driving them crazy: it would run perfectly for days, then suddenly stall at a stoplight. No check engine light, no warning. They had already replaced the fuel pump itself with no luck. After hooking up my scan tool and monitoring live data, I noticed the fuel pump duty cycle was erratic, dropping to zero just before the engine quit. This pointed directly to the FPCM. We installed a VIN-programmed module, and the problem was solved instantly. The original module was failing intermittently under heat soak, a common issue for these parts located on the vehicle’s frame.
Is Your Acadia Showing These Signs of FPCM Failure?
A faulty FPCM can mimic other fuel system problems. Here are the most common indicators I’ve diagnosed in my shop that point directly to this module:
- ✔ Engine cranks but will not start.
- ✔ Sudden stalling, especially when warm or at idle.
- ✔ Vehicle enters ‘Reduced Power’ mode.
- ✔ Hesitation or stumbling during acceleration.
- ✔ An active Check Engine Light with codes like P069E, P0230, or U0109 (Lost Communication With Fuel Pump Control Module).
- ✔ Inconsistent fuel pressure readings.
A Straightforward Guide to Installation
Replacing the 2013-2014 Acadia Fuel Pump Module is a job most DIYers with basic tools can handle. Because we program it for you, there are no complex computer steps required on your end. The module is typically located on the rear crossmember.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the FPCM mounted to the rear crossmember, near the spare tire area. It’s a small, black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note their orientation. Then, unbolt the module from the frame. These bolts can be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed module into the same location. Ensure it is secure.
- Reconnect: Plug the electrical connectors firmly into the new FPCM. You should hear a click as they lock into place.
- Final Step: Reconnect the negative battery terminal. Start the vehicle and let it idle for a few minutes to confirm the repair.

Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN is required so we can program the module with the exact software and calibrations for your vehicle’s specific configuration. This ensures 100% compatibility and prevents communication errors that cause check engine lights or running issues.
Is this part difficult to install?
No, this is a straightforward replacement. Since the module comes pre-programmed, it’s a plug-and-play installation. Basic hand tools are all that’s needed. For the Acadia, it’s located on the rear crossmember.
What happens if I install a module that isn’t programmed?
An unprogrammed module will not work correctly. Your vehicle will likely not start, or it will run poorly and set multiple trouble codes. Our pre-programming service eliminates this problem entirely.
Is this the same as a fuel pump driver module?
Yes, the terms Fuel Pump Control Module (FPCM), Fuel Pump Driver Module (FPDM), and Fuel System Control Module (FSCM) are often used interchangeably for this component.
How do I send you my VIN?
After you complete your purchase, simply send us a message with your 17-digit VIN. We will program the module and then ship it out to you, typically within one business day.
