Is your 2012 Impala or other GM vehicle suddenly stalling, hesitating, or refusing to start? Before you condemn the fuel pump, the real culprit is often the Fuel System Control Module (FSCM). This critical component, also known as a fuel pump driver module, regulates the voltage sent to your fuel pump. When it fails, it can lead to a host of frustrating and unpredictable fuel delivery problems. I’ve seen it countless times in the shop: a perfectly good fuel pump gets replaced, but the problem persists because the FSCM was the root cause.
This is your reliable, cost-effective solution. We offer a genuine GM Fuel System Control Module that comes fully programmed to your vehicle’s specific VIN. Just provide us with your VIN after purchase, and our technicians will flash the module with the latest GM software updates. This means it arrives at your door ready for a straightforward installation, saving you a trip to the dealership and their expensive programming fees. Restore your vehicle’s performance and reliability with a part that’s guaranteed to work correctly right out of the box.
A Technician’s Notebook: The Fuel Pump That Wasn’t Bad
I remember a 2011 Silverado that came into my bay on a tow truck. The owner was frustrated, having already replaced the fuel pump himself after watching a video online. The truck would start sometimes, but would sputter and die under load. He was convinced he got a bad pump. I hooked up my scan tool and immediately saw what he missed: DTC P069E, “Fuel Pump Control Module Requested MIL Illumination.” A quick voltage check at the FSCM connector confirmed my suspicion. The module, exposed to years of road grime and moisture on the frame rail, was failing intermittently. We installed a new, programmed FSCM, and the truck ran perfectly. It’s a classic case where diagnosing the system, not just the part, saves time and money.
Is Your Vehicle Showing These Symptoms?
A failing FSCM can mimic a bad fuel pump. Look for these common warning signs before you start replacing more expensive parts. This 2012 Impala Fuel System Control Module is often the fix for:
- ✔ Engine stalling, especially when warm or under load
- ✔ Complete no-start condition, even with a cranking engine
- ✔ “Reduced Engine Power” message on the dashboard
- ✔ Hesitation or stumbling during acceleration
- ✔ Check Engine Light with codes P069E, P0230, or U0109
A Straightforward Guide to Installation
Replacing the FSCM is a job most DIYers can handle in their own driveway. For the 2012 Impala, the module is conveniently located in the right-hand rear quarter panel area, accessible from the trunk.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Module: On your 2012 Impala, access the trunk and remove the right-side trim panel to expose the FSCM. On trucks and SUVs, it is typically mounted on the left-hand frame rail near the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, remove the bolts or nuts holding the old module in place.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location and secure it with the original hardware.
- Final Connections: Plug the electrical connectors firmly into the new module. Re-install any trim panels you removed and reconnect the negative battery terminal.

Frequently Asked Questions
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the module with the exact software and calibrations your specific vehicle requires from GM. This ensures perfect compatibility and function without any extra steps.
What does “pre-programmed” mean for me?
It means the module is ready to install the moment you receive it. You will not need to take your car to a dealership or mechanic for expensive computer programming. It’s a true plug-and-play solution.
Where is the 2012 Impala Fuel System Control Module located?
On the 2012 Chevrolet Impala, the FSCM is located behind the trim panel in the right-hand (passenger side) rear quarter panel, inside the trunk.
Will this fix a P069E trouble code?
Yes, in the vast majority of cases, a faulty FSCM is the direct cause of a P069E code. Replacing the module with this pre-programmed unit is the correct repair for that fault.
Is this a difficult part to replace for a DIYer?
Not at all. For most owners with basic hand tools, this is a very straightforward replacement that can be completed in under an hour. The location on most vehicles is reasonably accessible.
