Restore Your Vehicle’s Performance with a Reliable Fuel System Solution
Is your 2010-2012 Buick Enclave, or another compatible GM vehicle, experiencing frustrating issues like engine stalling, a no-start condition, or an illuminated Check Engine Light? These are classic signs of a failing Fuel System Control Module (FSCM), also known as a fuel pump driver module. 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. This isn’t just an inconvenience; it’s a reliability issue that needs a definitive fix.
This is a direct-replacement FSCM that arrives at your door fully programmed to your vehicle’s specific VIN. We handle the complex part for you. By flashing the module with the latest GM software updates before it ships, we eliminate the need for an expensive trip to the dealership for programming. This is the efficient, cost-effective solution that both professional mechanics and DIY enthusiasts trust for a successful repair.
Case Study: A Tricky Diagnosis
I remember a 2011 Buick Enclave that came into my shop. The owner was frustrated with an intermittent no-start problem and a P069E code that kept reappearing. Another shop had already replaced the fuel pump, but the issue persisted. After checking fuel pressure and wiring, my diagnostic process pointed directly to the FSCM. These modules, often mounted on the frame or crossmember, are exposed to harsh conditions—heat, moisture, and vibration—which leads to internal failure. We installed one of our pre-programmed modules, and the problem was solved instantly. The customer was back on the road the same day, saving hundreds compared to a dealer visit and further misdiagnosis.
Is Your Vehicle Showing These Signs?
A failing FSCM can mimic other fuel system problems. Here are the most common indicators that point to this module being the culprit:
- ✔ Engine cranks but will not start
- ✔ Intermittent stalling, especially while driving
- ✔ Rough idle or engine hesitation
- ✔ Reduced engine power and poor acceleration
- ✔ Check Engine Light with codes like P069E, P0230, or U0109 (Loss of Communication with FSCM)
- ✔ A noticeable whining from the fuel pump or no sound at all
A Straightforward Guide to Installation
For the 2010-2012 Buick Enclave, this module is typically located on the rear crossmember, making it accessible for a DIY repair. While locations vary on other models, the process is generally similar. Always consult a service manual for your specific vehicle.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the old FSCM. On many trucks and SUVs, it’s on the driver-side frame rail. On the Enclave, Acadia, and Traverse, check the rear crossmember.
- 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 FSCM into place. Ensure it’s secure to prevent vibration damage.
- Connect and Finalize: Plug the electrical connectors firmly into the new module. Reconnect the negative battery terminal.
- Verify the Repair: Start the vehicle. It should now run smoothly. Clear any stored diagnostic trouble codes with a scan tool.

Frequently Asked Questions
How does the programming process work?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. Our technicians will then program the module with the latest official GM software for your exact vehicle before shipping it out. This ensures it’s ready for installation right out of the box.
Do I need any special tools to install this?
No special tools are required. Basic hand tools like a socket set and ratchet are typically all you need to unbolt the old module and install the new one. The most important part—the programming—is already done for you.
Is this part the same as a Fuel Pump Driver Module (FPDM)?
Yes. Different manufacturers use different names, but Fuel System Control Module (FSCM) and Fuel Pump Driver Module (FPDM) refer to the same component that controls the vehicle’s fuel pump.
What if I install this and my problem doesn’t go away?
While this module is a very common failure point for the symptoms listed, vehicle diagnostics can be complex. If the issue persists, it’s possible another component in the fuel system (like the pump itself or wiring) is at fault. This module will, however, rule out the FSCM as the source of the problem.
Where is the FSCM located on my 2011 Chevy Silverado?
On most GM trucks from this era, including the Silverado, Sierra, Tahoe, and Yukon, the FSCM is mounted on the driver’s side frame rail, typically above the spare tire. It’s exposed to the elements, which is a common reason for its failure.
