Is Your Vehicle Stalling, Hesitating, or Refusing to Start?
A faulty Fuel System Control Module (FSCM) is one of the most common reasons for frustrating and unpredictable fuel delivery problems in many GM vehicles. If you’re experiencing a sudden loss of power, a check engine light that won’t go away, or a vehicle that just won’t run, you’re in the right place. This isn’t just a replacement part; it’s a complete, ready-to-install solution designed to get you back on the road quickly and reliably.

An Expert’s Insight on FSCM Failure
As a technician, I’ve seen dozens of these modules fail. On most trucks and SUVs, GM mounted the FSCM on the frame rail, exposing it to years of water, road salt, and vibration. This leads to internal corrosion and eventual failure. The updated software we install helps the module operate more efficiently, reducing heat and stress. By purchasing a Programmed 20791901 Fuel System Control Module from us, you’re not just replacing a failed part—you’re installing a more robust and reliable solution that bypasses the dealership’s high costs for parts and labor.
Frequently Asked Questions
What do I need to do after I place my order?
After you complete your purchase, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. You can typically send it through the platform’s messaging system or add it as a note to your order.
Is this part difficult to install?
For most vehicles, the installation is straightforward. The module is typically located on the driver’s side frame rail or in the rear compartment. It involves disconnecting the battery, unplugging the electrical connectors, and removing a few bolts. Because our module is pre-programmed, no special tools or software are needed. It’s a direct swap.
Will this fix my Check Engine Light?
If your Check Engine Light is on due to codes related to the Fuel Pump Driver Module (like P069E), then yes, this part is the correct solution. After installation, you may need to clear the codes with a standard OBD-II scanner, or they may clear on their own after a few drive cycles.
Where can I find my VIN?
Your VIN is a 17-digit number located on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
My old module has a different part number. Will this still work?
Yes, this module is a compatible replacement for several part numbers, including 20827745, 20877116, and 20850927. As long as your vehicle is listed in our compatibility chart, this module will function correctly once programmed to your VIN.
