Restore Your Buick’s Performance and Reliability
Is your 2011-2012 Buick Regal experiencing frustrating issues like sudden stalling, hesitation during acceleration, or a complete no-start condition? Before you suspect the fuel pump, the real culprit is often the Fuel System Control Module (FSCM). This vital component acts as the brain for your fuel pump, regulating its voltage to ensure your engine gets the precise amount of fuel it needs. When it fails, it can leave you stranded and with a persistent Check Engine Light.
This is a direct-fit, VIN-programmed 2011-2012 Regal FSCM that solves these common problems. We take the guesswork and dealer expense out of the equation. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and our experts will program the module with the latest GM software specifically for your car. It arrives at your door ready for a straightforward installation, getting you back on the road with confidence.
From the Diagnostic Bay: A Common Regal Scenario
Just last month, a 2012 Regal was towed to my shop. The owner had already replaced the fuel pump himself, but the car would still crank but not start. He was frustrated and out of pocket for a part he didn’t need. A quick scan showed a U0109 code—Lost Communication With Fuel Pump Control Module. We located the FSCM in the driver’s side rear quarter panel, and a check with a test light confirmed it wasn’t sending power out. After installing one of our pre-programmed modules, the car fired right up. It’s a classic case I’ve seen dozens of times; the FSCM is a common failure point that often gets misdiagnosed.
Is Your Regal Showing These Signs?
A failing FSCM can manifest in several ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Engine stalls unexpectedly, especially when coming to a stop
- ✔ Vehicle cranks but refuses to start
- ✔ Hesitation or stumbling upon acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Illuminated Check Engine Light with codes such as P069E, U0109, or P0230
A Straightforward Guide to Installation
Replacing the 2011-2012 Regal FSCM is a job most DIYers can handle with basic tools. The module is located inside the trunk, behind the driver’s side trim panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Access the Module: Open your trunk and remove the floor covering. You’ll need to pull back or remove the driver’s side (LH) interior trunk trim panel to expose the rear quarter panel area.
- Locate the FSCM: You will see the Fuel System Control Module mounted to the vehicle’s body in this area. It’s a small black box with an electrical connector.
- Disconnect and Remove: Carefully press the release tab on the electrical connector and pull it straight off the module. Then, remove the bolts or nuts holding the old FSCM in place.
- Install the New Module: Mount your new, pre-programmed FSCM in the exact same position and secure it with the original hardware.
- Final Connections: Firmly plug the electrical connector into the new module until it clicks. Reinstall the trunk trim panel and reconnect the negative battery terminal.
- Key Cycle: Turn the key to the ‘On’ position for 10 seconds (without starting the engine), then turn it off. Repeat this process 2-3 times to allow the vehicle’s systems to recognize the new module before starting the engine.

Frequently Asked Questions
What does an FSCM do?
The Fuel System Control Module (FSCM), sometimes called a Fuel Pump Driver Module, is a small computer that controls the voltage sent to your electric fuel pump. This allows it to precisely manage fuel pressure for optimal engine performance and efficiency.
Is this module really plug-and-play?
Yes! The biggest benefit of our service is that we program the module to your car’s specific VIN before we ship it. This means you don’t need a trip to the dealership for expensive programming. It arrives ready to be installed.
Where is this located on my 2011-2012 Regal?
On the 2011-2012 Buick Regal, the FSCM is located inside the trunk, mounted behind the driver’s side (left-hand) interior trim panel.
Will this fix a Check Engine Light with a P069E code?
Yes, in most cases. Code P069E indicates a performance issue or a fault request from the Fuel System Control Module itself. Replacing a faulty FSCM is the direct and proper repair for this diagnostic trouble code.
How do I give you my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
