Restore Your Impala’s Performance with a VIN-Programmed Fuel Module
There’s nothing more frustrating than an engine that cranks but won’t start, or one that stalls unexpectedly in traffic. If your 2013-2016 Chevrolet Impala is suffering from hesitation, poor acceleration, or a no-start condition, the culprit is often a failing Fuel Pump Control Module (FPCM). This component, also known as a Fuel System Control Module (FSCM), is critical for regulating the voltage sent to your fuel pump. When it fails, fuel delivery becomes erratic, leading to a host of performance and reliability problems.
As a technician with over two decades of experience, I’ve seen these modules cause intermittent issues that are a nightmare to diagnose. This isn’t just a replacement part; it’s a complete solution. We take the guesswork out of the repair by programming this module specifically for your vehicle using your VIN. This means it arrives at your door with the latest GM software updates already installed, ready for a direct, plug-and-play installation. You get a reliable fix without the expensive trip to the dealership for programming.
A Technician’s Notebook: The Intermittent Stall
A customer brought in a 2014 Impala Limited with a complaint that stumped two other shops: it would stall randomly, sometimes at a stoplight, sometimes on the highway. There were no consistent trouble codes, just a history log of a U0109 (Lost Communication with Fuel Pump Control Module). After checking wiring and grounds, we focused on the FPCM. These modules can suffer from internal electronic fatigue, causing them to drop communication intermittently. We installed a VIN-programmed module, and the problem was solved instantly. The pre-programming was key, as it ensured perfect communication with the car’s ECM from the moment it was connected.
Is Your Impala Showing These Symptoms?
A failing FPCM can manifest in several ways. If you’re experiencing any of the following, this module is the most likely solution for your 2013-2016 Impala Fuel Module issues.
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when warm
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes like P0230, P0627, P069E, or U0109
A Straightforward Guide to Installation
Replacing the FPCM on your Impala is a manageable job for a DIYer with basic tools. For the 2013-2016 Impala (Limited), the module is located in the trunk area, behind the trim on the right-hand (passenger) side quarter 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 necessary clips and trim panels on the passenger side to expose the FPCM.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Then, unbolt it from its mounting bracket. It’s typically held on by a couple of small bolts or nuts.
- Install the New Module: Bolt the new, pre-programmed module into place. Ensure it is securely fastened.
- Reconnect: Plug the electrical connectors firmly into the new module. You should hear a click as they lock into place.
- Final Steps: Reinstall the trunk trim panels and reconnect the negative battery terminal. Start the vehicle to confirm the repair is successful.

Frequently Asked Questions
Why do you need my VIN?
Your VIN (Vehicle Identification Number) allows us to program the module with the exact software and calibrations for your specific vehicle. This ensures seamless communication with other computers on your car and guarantees proper function without a trip to the dealer.
Is this module truly plug-and-play?
Yes. Because we program it to your VIN before shipping, it is ready for installation right out of the box. No further programming or dealer visits are required.
What tools will I need for installation on my Impala?
You will typically need a basic socket set (for the mounting bolts and battery terminal) and a trim removal tool to safely pop off the interior panels without damaging them.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit VIN. We cannot ship the part until we receive this information for programming.
Will this fix a fuel pressure code?
In many cases, yes. The FPCM directly controls the fuel pump’s output. If the module is faulty, it can cause incorrect fuel pressure, which often triggers diagnostic trouble codes. This part is a direct fix for that issue.
