Restore Your Vehicle’s Fuel Delivery and Performance
Is your 2009 GMC Acadia or other GM vehicle experiencing frustrating and potentially dangerous issues like stalling, engine hesitation, or a complete no-start condition? Before you condemn the in-tank fuel pump—an expensive and labor-intensive job—consider the component that controls it. This is a direct-fit Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM), that arrives at your door pre-programmed to your vehicle’s specific VIN. We handle the complex part, so you can handle the simple installation.
A Technician’s Notebook: The Misleading No-Start
I remember a 2009 Acadia that was towed into the shop. The owner had already replaced the fuel pump himself, but the vehicle still wouldn’t start. He was convinced he got a bad pump. My first check wasn’t the pump, but the FPCM, located on the rear crossmember. These modules are exposed to road salt, water, and debris, and this one was heavily corroded. A quick scan showed code U0109 – Lost Communication With Fuel Pump Control Module. We swapped in a VIN-programmed module, and the engine fired right up. It’s a classic case I’ve seen dozens of times; the FPCM fails far more often than the pump itself, saving customers hundreds in parts and labor when diagnosed correctly.
Why Choose a VIN-Programmed Module?
Modern vehicles rely on precise communication between modules. A new FPCM won’t work correctly out of the box; it must be programmed by a dealer or a shop with expensive scan tools. We eliminate that entire step. By providing us with your VIN during checkout, you receive a module that is truly plug-and-play. We load the latest GM software updates, which often address factory bugs and improve fuel delivery logic. This ensures your 2009 Acadia Fuel Pump Module operates exactly as the engineers intended, restoring stable fuel pressure and engine performance.
Is Your GM Vehicle Showing These Signs?
A failing FPCM can mimic a bad fuel pump. Look out for these common symptoms before making a costly misdiagnosis:
- ✔ Engine cranks but will not start
- ✔ Intermittent stalling, especially under load or when warm
- ✔ Stuttering or hesitation during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can tackle in their own driveway with basic hand tools. Follow these general steps for a successful repair.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Module: On most GM trucks and SUVs (like the Tahoe, Silverado, Sierra), the FPCM is mounted on the driver’s side frame rail, near the spare tire. On crossovers (like the Acadia, Traverse, Enclave), it’s typically on the rear subframe or crossmember. On vans, it’s also on the LH frame rail.
- Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly. Then, remove the bolts or nuts securing the old module to the frame. It may be corroded, so a little penetrating oil can help.
- Install the New Module: Bolt your new, pre-programmed FPCM into place. Ensure it is mounted securely.
- Reconnect and Finalize: Plug the electrical connectors back in until they click, ensuring a solid connection. Reconnect the negative battery terminal.
- Prime the System: Turn the key to the ‘On’ position (without starting the engine) for a few seconds to allow the fuel pump to prime the system. Start the vehicle and check for proper operation.

Frequently Asked Questions
What does a Fuel Pump Control Module do?
The FPCM is a small computer that receives commands from the main Engine Control Module (ECM) and precisely regulates the voltage sent to the fuel pump. This controls the pump’s speed and the vehicle’s fuel pressure for optimal efficiency and performance.
Why do you need my VIN to program it?
Every GM vehicle has specific software calibrations. Programming the module to your Vehicle Identification Number (VIN) ensures it has the exact software and updates required for your specific model, engine, and emissions equipment. This makes the part work perfectly right out of the box.
Is this a difficult part to replace myself?
For most individuals with basic mechanical skills, this is a very manageable job. The module is typically located on the vehicle’s frame or subframe and is accessible with common hand tools. Since we pre-program it, no special electronic tools are needed.
What happens if I ignore a failing FPCM?
Ignoring the symptoms can lead to more severe problems, including leaving you stranded with a no-start condition, causing catalytic converter damage from an improper fuel mixture, and decreased fuel economy.
How can I be sure this is the problem and not my fuel pump?
While symptoms overlap, a key indicator is the location. FPCMs on the frame are highly susceptible to corrosion. A visual inspection can often reveal a swollen or corroded module. Diagnostic codes like U0109 (loss of communication) point directly to the module or its wiring, not the pump.
