Restore Your Vehicle’s Performance with a VIN-Programmed Fuel Module
If your Chevrolet Impala, Silverado, or other compatible GM vehicle is suffering from stalling, hesitation, or a frustrating no-start condition, the culprit is often a failing Fuel System Control Module (FSCM). As an experienced technician, I’ve seen countless drivers replace their fuel pump, only to find the real issue was this critical electronic component. The FSCM acts as the brain for your fuel pump, regulating voltage to ensure precise fuel pressure for optimal engine performance and efficiency. When it fails, your entire fuel delivery system is compromised.
This isn’t just a replacement part; it’s a complete solution. We take the hassle and high cost out of the repair by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN). This means you get a part that’s loaded with the latest GM software updates and is ready for a true plug-and-play installation, eliminating the need for an expensive trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest, shipping you a module that’s ready to restore your vehicle’s reliability right out of the box.
A Technician’s Notebook: The Misleading P069E Code
A 2011 Silverado 1500 was towed into my bay with a classic crank-no-start condition. The owner had already replaced the fuel pump himself, but the truck still wouldn’t fire up. A quick scan showed a persistent DTC P069E: Fuel Pump Control Module Requested MIL Illumination. While this code points to the FPCM (another name for the FSCM), many people mistakenly chase the pump. I connected a multimeter to the pump connector and saw erratic voltage during cranking—a dead giveaway. The FSCM, exposed to years of road grime and moisture on the frame rail, had failed internally. Installing a new, programmed module had the truck running perfectly in under 30 minutes, saving the customer from further misdiagnosis and expense.
Is Your GM Vehicle Showing These Fuel System Alarms?
A faulty FSCM can manifest in several ways. If you’re experiencing any of the following, this module is the likely solution.
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or during acceleration
- ✔ Reduced engine power or ‘limp mode’ activation
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
- ✔ Inconsistent fuel pressure readings
- ✔ A fuel pump that doesn’t prime when the key is turned
A Straightforward Guide to Your FSCM Replacement
Replacing the 2012 Impala Fuel Module is a job most DIYers can handle with basic tools. The location varies by model, but the process is generally similar.
- Step 1: Provide Your VIN. After placing your order, send us your 17-digit VIN. We cannot ship your part until we program it.
- Step 2: Safety First. Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Step 3: Locate the Old Module. On the 2012 Impala, it’s typically in the right-hand rear quarter panel area. On trucks like the Silverado or Tahoe, it’s usually mounted on the driver-side frame rail. Consult a service manual for your specific vehicle’s location.
- Step 4: Disconnect and Remove. Carefully unplug the electrical connector(s). Then, remove the bolts or nuts securing the module to the chassis.
- Step 5: Install the New Module. Mount your new, pre-programmed FSCM in the same location and secure it with the original hardware. Reconnect the electrical harness.
- Step 6: Final Steps. Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10-15 seconds to allow the system to prime, then start the engine. Your Check Engine Light should be off, and performance restored.

Frequently Asked Questions
Do I need to do any programming myself?
No. This is the biggest benefit of our service. We flash the module with the latest GM software using the VIN you provide, so it arrives ready to install. No special tools or dealer visits are required.
How do I provide my VIN?
After you complete your purchase, please send us a message with your 17-digit Vehicle Identification Number. We cannot process your order without it.
Is this part compatible with other part numbers?
Yes, this FSCM, part number 20827745, directly replaces part numbers 20791901, 20877116, and 20850927, ensuring broad compatibility across the GM lineup.
What happens if I install it without programming?
An unprogrammed module will not communicate correctly with your vehicle’s other computers, like the Engine Control Module (ECM). This will result in a no-start condition and communication error codes. Our pre-programming service prevents this entirely.
