Restore Your Acadia’s Performance and Reliability
Is your 2013-2014 GMC Acadia experiencing frustrating issues like stalling, sputtering, or a complete no-start condition? A faulty Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM), is one of the most common culprits I see for these exact symptoms. As a technician with over two decades of experience, I’ve seen how a failing FPCM can leave you stranded and facing a confusing diagnosis. This module is the brain behind your fuel pump, and when it fails, your engine is starved of the precise fuel pressure it needs to run smoothly.
We offer a dependable and straightforward solution. This genuine GM control module, part number 20964305, arrives at your door fully programmed with the latest factory software, specifically matched to your vehicle’s VIN. This critical step eliminates the need for an expensive trip to the dealership for programming, saving you both time and money. You get a part that’s ready to install right out of the box, restoring your vehicle’s fuel delivery system to its original operating standards.
Real-World Repair Story
Real-World Repair Story
A customer brought in their 2014 Traverse—which uses the same FPCM as the Acadia—with an intermittent stalling problem that two other shops couldn’t solve. The engine would die at stoplights, but there was no consistent Check Engine Light. When I hooked up my scan tool and monitored live data, I saw the fuel pump duty cycle dropping to zero right before the engine quit. There were no fuel pump circuit codes, just a stored P069E (Fuel Pump Control Module Requested MIL Illumination). These modules, often mounted on the frame or crossmember, are exposed to water and road salt, which corrodes the internal circuits over time. We replaced it with a VIN-programmed module, and the Traverse has been running flawlessly ever since. It’s a classic failure I’ve seen dozens of times.
Is Your Vehicle Showing These Symptoms?
- ✔ Engine cranks but refuses to start.
- ✔ Stalling, especially when coming to a stop or at idle.
- ✔ Severe hesitation or sputtering during acceleration.
- ✔ Reduced engine power and poor fuel economy.
- ✔ A Check Engine Light with diagnostic trouble codes (DTCs) like P069E, P0230, or U0109.
- ✔ A whining noise from the fuel pump area as it struggles to maintain pressure.
A Straightforward Guide to Installation
Replacing the FPCM on your Acadia is a manageable job for a DIYer with basic tools. The module is typically located on the rear subframe crossmember, near the fuel tank. Always consult a service manual for your specific vehicle’s procedure.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Safely raise the rear of the vehicle and secure it on jack stands. You will find the FPCM mounted to the rear crossmember. It’s a small black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle to avoid breaking the locking tabs. Then, unbolt the module from the frame.
- Install the New Module: Bolt your new, pre-programmed FPCM into place. Ensure it is securely fastened.
- Reconnect: Plug the electrical connectors firmly into the new module until they click into place.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10-15 seconds to allow the system to prime before starting the engine. Your vehicle is ready to go!
