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 a wide range of GM vehicles. If you’re experiencing sudden engine stalls, a crank-no-start condition, or a persistent Check Engine Light, your FSCM is the likely culprit. This isn’t just an inconvenience; it’s a critical failure that can leave you stranded. Instead of paying for expensive diagnostics and programming fees at a dealership, get the definitive, ready-to-install solution right here.
Common Symptoms of a Failing FSCM & Your Solution
Your vehicle’s computer relies on the FSCM to manage the fuel pump and ensure the engine receives the precise amount of fuel it needs. When it fails, you’ll notice one or more of the following issues:
- Engine stalling, especially while driving
- Vehicle cranks but will not start
- Hesitation or stumbling during acceleration
- Noticeable loss of engine power
- Reduced fuel economy
- Check Engine Light with codes like P069E, P0230, or P0606

Expert Insight: Why FSCMs Fail and Why Programming Matters
As a technician with over 20 years of experience, I’ve replaced hundreds of these modules. On most GM trucks and SUVs, the FSCM is mounted to the frame rail, where it’s exposed to constant vibration, moisture, and road salt. This harsh environment leads to internal circuit board failures over time. Simply replacing it with another used module without the latest software is a temporary fix at best. Our programmed fuel system control module 20791901 ensures you get the most robust software corrections from GM, providing a much more durable and reliable long-term solution.
Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. This makes it a true plug-and-play part, saving you hundreds of dollars in dealership programming fees.
What is the process after I place my order?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship your part until we receive this information. Once we have your VIN, we will program the module and typically ship it within one business day.
Where is the FSCM located on my vehicle?
The location varies by model. On most trucks and large SUVs (like the Silverado, Tahoe, and Escalade), it’s mounted on the driver’s side frame rail, often near the spare tire. On cars and crossovers (like the Impala or Acadia), it’s typically located in the trunk area or near the rear crossmember.
Will this fix my Check Engine Light for code P069E?
P069E (Fuel Pump Control Module Commanded On) is a very common code indicating a fault with the FSCM. While proper diagnosis is always recommended, this programmed fuel system control module 20791901 is the definitive fix for this code in the vast majority of cases.
How do I find my vehicle’s VIN?
Your 17-digit VIN can be found on your vehicle’s registration, your insurance card, or on a placard on the driver’s side of the dashboard visible through the windshield.
