Common Symptoms & Your Solution
A failing FSCM can cause a host of frustrating and intermittent issues. If you’re experiencing any of the following, this module is the likely fix:
- No-Start Condition: The engine cranks but won’t start due to a lack of fuel pressure.
- Stalling: The engine may stall unexpectedly while driving or at idle.
- Reduced Engine Power: Your vehicle may enter a ‘limp mode’ with a warning on the dash.
- Check Engine Light: Often accompanied by diagnostic trouble codes (DTCs) such as P069E, P0230, or P0606.
This pre-programmed module directly addresses these issues by restoring precise control over your fuel pump, ensuring your engine gets the exact amount of fuel it needs for smooth, reliable operation.

From the Technician’s Bench: We see these modules fail constantly. On most trucks and SUVs, the FSCM is mounted on the frame rail, completely exposed to road salt, water, and vibration. Over time, moisture gets inside and corrodes the circuit board, leading to all sorts of intermittent electrical gremlins that are a nightmare to diagnose. By replacing it with this Programmed 20791901 Fuel System Control Module, you’re not just fixing the immediate problem; you’re installing a fresh, reliable component that solves a known weak point in the system.
Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s 17-digit Vehicle Identification Number (VIN) is like its fingerprint. It contains specific information about its engine, transmission, and factory options. We use the VIN to load the exact, correct software from GM onto the module before we ship it. This ensures it communicates perfectly with your vehicle’s other computers, making the installation truly plug-and-play.
Is this part difficult to install?
For most trucks and SUVs like the Silverado or Tahoe, the FSCM is located on the driver’s side frame rail, often near the spare tire. Installation typically involves disconnecting the battery, unplugging two electrical connectors, and removing a few bolts. It’s a job that can be done by a confident DIYer with basic hand tools in under an hour. Always consult a repair manual for your specific vehicle’s procedure.
Will this fix a Check Engine Light with code P069E?
Yes, the DTC P069E (Fuel Pump Control Module Commanded On) is one of the most common codes indicating a faulty FSCM. While you should always perform a proper diagnosis, this Programmed 20791901 Fuel System Control Module is the definitive repair for this code in the vast majority of cases.
What happens if I install a module that isn’t programmed?
An unprogrammed module will not work. The vehicle’s main computer will not recognize it, and the fuel pump will not activate. Your vehicle will not start. Our service eliminates this entire problem by delivering a part that is ready for immediate operation.
Is this compatible with part number 20877116?
Yes. This module is a direct replacement for several part numbers, including 20877116, 20791901, 20827745, and 20850927. As long as your original module carries one of these numbers, this part will be a perfect fit and function.
How do I send you my VIN after purchase?
After you complete your purchase, simply send us a message with your 17-digit VIN. We will confirm receipt and begin the programming process. We cannot ship your order until we receive the VIN.
