Restore Your 2012 Impala’s Performance and Reliability
Is your 2012 Chevrolet Impala experiencing frustrating issues like stalling, hesitation, or a complete no-start condition? Before you consider replacing the fuel pump, the real culprit is often the Fuel System Control Module (FSCM). As a master technician with over two decades of experience, I’ve seen this exact scenario countless times. The FSCM is the brain that tells your fuel pump how much pressure to deliver. When it fails, it starves the engine of fuel, leading to poor performance and leaving you stranded. This module is a direct-fit, VIN-programmed solution to get your vehicle running smoothly again.
We take the guesswork and high costs out of the repair. Unlike a trip to the dealership, this 2012 Impala FSCM arrives at your door pre-programmed with the latest GM software specific to your vehicle’s VIN. This means no expensive programming tools or additional labor costs are required. It’s a true plug-and-play fix that restores factory performance and efficiency.
A Technician’s Notebook: The Fuel Pump That Wasn’t Bad
I had a 2012 Impala come into my bay with a classic ‘crank, no start’ complaint. The owner had already replaced the fuel pump himself, but the problem persisted. He was frustrated and out of money. Hooking up my scan tool, I wasn’t surprised to see code U0109 – Lost Communication With Fuel Pump Control Module. Instead of just throwing another part at it, we checked the power and ground at the FSCM connector in the right rear quarter panel. Everything was good. The module itself had simply failed internally, a common issue due to heat and vibration. We installed a VIN-programmed FSCM, and the car fired right up. It’s a powerful reminder to diagnose the entire system, not just the most obvious part.
Is Your Vehicle Showing These Symptoms?
A failing FSCM can mimic a bad fuel pump. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Engine cranks but will not start
- ✔ Vehicle starts and then immediately stalls
- ✔ Severe hesitation or stumbling during acceleration
- ✔ “Reduced Engine Power” message on the dashboard
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
- ✔ Inconsistent fuel pressure readings
A Straightforward Guide to Installation
Installing your new 2012 Impala FSCM is a manageable job for a DIY enthusiast. For the 2012 Impala, the module is located in the trunk area, behind the right-hand side trim panel.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Access the Module: Open the trunk and remove the clips or fasteners holding the right-side carpeted trim panel in place. Gently pull it back to expose the module.
- Disconnect and Remove: Unplug the electrical connector(s) from the old FSCM. Then, remove the nuts or bolts securing the module to the vehicle body.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location and secure it with the original hardware.
- Reconnect and Test: Plug the electrical connector(s) firmly into the new module. Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds before starting the engine to allow the system to prime. Start the vehicle to confirm the repair.
- Reassemble: Once you’ve confirmed the vehicle runs correctly, reinstall the trunk trim panel.

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN is required so we can program the module with the exact software and calibrations from GM for your specific car. This ensures perfect compatibility and function without needing a trip to the dealer.
Is this part difficult to install on my 2012 Impala?
No, for the Impala, the installation is relatively simple for someone with basic mechanical skills. It’s located behind the trunk liner on the passenger side and involves unplugging the old one and bolting in the new one.
Will this fix a P069E trouble code?
Yes, the Diagnostic Trouble Code (DTC) P069E is one of the most common codes indicating a fault with the Fuel System Control Module. Replacing it with this pre-programmed unit is the correct repair for that code.
What happens if I install it without programming?
An unprogrammed module will not communicate correctly with your vehicle’s Engine Control Module (ECM), and your car will likely not start or run properly. Our pre-programming service handles this for you, making it a plug-and-play part.
Is this the same as a fuel pump driver module?
Yes, the terms Fuel System Control Module (FSCM) and Fuel Pump Driver Module (FPDM) are often used interchangeably for this component. It performs the same function: controlling the voltage and operation of the in-tank fuel pump.
