Restore Your Vehicle’s Performance and Reliability
Is your 2009 GMC Acadia or other GM vehicle experiencing frustrating issues like stalling, hesitation, or a complete no-start condition? Before you condemn the fuel pump, the real culprit is often the Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This critical component regulates 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 facing a confusing diagnosis. This module is the definitive solution, providing a reliable and permanent fix to these common problems.
Case Study: A Tricky Diagnosis
I remember a 2009 Chevy Traverse—which shares its platform with the Acadia—that came into my shop on a tow truck. The owner had already replaced the fuel pump himself, but the vehicle would still intermittently stall at red lights and sometimes refuse to restart for 20-30 minutes. He was frustrated and out of ideas. A quick scan showed a P069E code (Fuel Pump Control Module Requested MIL Illumination). Instead of just guessing, we hooked up a scope to the FPCM output. The voltage to the pump was erratic and would sometimes drop to zero, starving the engine of fuel. The new, pre-programmed FPCM fixed it instantly. It’s a classic case where throwing the most expensive part at the problem (the fuel pump) wasn’t the right answer.
Is Your GM Vehicle Showing These Signs?
- ✔ Engine stalls unexpectedly while driving or at idle
- ✔ Vehicle cranks but refuses to start
- ✔ Hesitation or stumbling during acceleration
- ✔ “Reduced Engine Power” message on the dashboard
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P025A, or P0230
A Straightforward Guide to Installation
One of the biggest benefits of this module is that it arrives programmed and ready for installation. For a DIYer with basic tools, this is a very manageable job. On the 2009 Acadia, the module is typically located on the rear crossmember, making it accessible without dropping the fuel tank.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FPCM. On many GM SUVs and trucks, it’s mounted to the frame rail or a crossmember near the spare tire. Check your specific model’s service information for the exact location.
- Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle with the locking tabs, as they can become brittle over time. Then, unbolt the old module from its mounting location.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Reconnect the electrical connectors, ensuring they click securely into position.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds (without starting) to allow the system to prime, then start the engine. Your vehicle should now run smoothly.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We will program the module with the latest GM software specific to your vehicle before shipping it out.
What does the Fuel Pump Control Module (FPCM) do?
The FPCM acts as a smart relay. It receives commands from the Engine Control Module (ECM) and precisely controls the speed of the fuel pump. This ensures optimal fuel pressure and efficiency under all driving conditions, which is something a simple on/off relay cannot do.
Is this part truly plug-and-play?
Yes. Because we program the module to your specific VIN before shipment, it arrives ready to be installed without any need for additional programming or calibration from a dealership. This saves you significant time and money.
Will this fix a P069E trouble code?
A P069E code is one of the most common indicators of a failing FPCM. While you should always perform a complete diagnosis, in a vast majority of cases I’ve seen in my shop, replacing the FPCM with a correctly programmed unit is the proper fix for this code.
How do I know if my fuel pump or the FPCM is bad?
It can be tricky. A common sign of FPCM failure is intermittent stalling, whereas a completely failed fuel pump usually results in a consistent no-start condition. The best way to be certain is to test the voltage going to the fuel pump from the FPCM. If the voltage is erratic or absent when it should be present, the FPCM is the likely cause.
