Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
There’s nothing more frustrating than a vehicle you can’t rely on. If your Chevrolet, GMC, or Cadillac is suddenly experiencing issues like engine stalling, a long crank time, a check engine light, or a complete no-start condition, a failing Fuel System Control Module (FSCM) is the most likely culprit. This critical component, often called a fuel pump driver module, regulates the voltage to your fuel pump. When it fails, it leaves you stranded. Don’t let a faulty module compromise your vehicle’s dependability—get the definitive, hassle-free solution right here.
Common Symptoms & Your Solution
A failing FSCM can manifest in several ways, often triggering specific Diagnostic Trouble Codes (DTCs). If your scanner is showing codes like P069E, P0230, or P0606, you’ve found your problem.

Expert Insight: Why a Pre-Programmed Module Matters
As a technician, I’ve seen countless GM trucks and SUVs sidelined by this exact part. The original FSCM is typically mounted on the frame rail, where it’s exposed to road salt, moisture, and vibration, leading to internal corrosion and failure. Many people are tempted to grab a used module from a salvage yard, but that’s a huge mistake. A used module is not programmed for your vehicle and will not work, leaving you back at square one. Our Programmed Fuel System Control Module 20791901 completely bypasses this problem. You get a fresh module, loaded with the most stable software for your VIN, ensuring the job is done right the first time.
Frequently Asked Questions
How does the programming process work?
It’s simple! After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians will use this information to flash the module with the specific GM software for your truck or SUV before we ship it to you.
Do I need to do anything after installation?
No. Because the module is pre-programmed to your vehicle, no further calibration or setup is required. It is a true plug-and-play installation. We do recommend clearing any existing trouble codes with a scanner after the part is installed.
Where is this module located on my vehicle?
On most trucks and SUVs like the Silverado, Sierra, Tahoe, and Suburban, the FSCM is located on the driver’s side frame rail, typically above the spare tire. It’s held in place with a few small bolts.
Will this fit if my original part number is 20877116?
Yes. This module is a direct, compatible replacement for several part numbers, including 20791901, 20827745, 20877116, and 20850927. It will function identically to your original part.
