Is Your GM Vehicle Stalling, Hesitating, or Refusing to Start?
A faulty Fuel System Control Module (FSCM) is one of the most common and frustrating issues for owners of GM trucks, SUVs, and cars. If you’re experiencing symptoms like an engine that cranks but won’t turn over, sudden stalling while driving, a persistent Check Engine Light, or inconsistent fuel gauge readings, your FSCM is the likely culprit. Don’t let a small electronic box leave you stranded. This direct-replacement module is the definitive solution to restore your vehicle’s performance and your confidence on the road.
Common Symptoms & Your Solution
A failing FSCM can trigger a range of diagnostic trouble codes (DTCs) and noticeable performance problems. This module is the proven fix for issues including:
- DTC P069E: Fuel Pump Control Module Requested MIL Illumination
- DTC P0230: Fuel Pump Primary Circuit Malfunction
- Engine cranks but fails to start
- Vehicle starts and then immediately stalls
- Severe engine hesitation or stumbling during acceleration
- Reduced engine power and poor fuel economy
This isn’t just a replacement part; it’s a complete, ready-to-install solution.

Expert Insight: Why Do These Modules Fail?
As a technician with over 20 years of experience, I’ve replaced hundreds of these modules. On many GM trucks and SUVs, the FSCM is mounted on the frame rail, directly exposed to the elements. Over years of heat cycles, moisture, road salt, and vibrations, the internal circuit board develops microscopic cracks or the components fail from corrosion. The initial symptom is often an intermittent stall that drivers might ignore, but it eventually leads to a complete no-start condition. Installing a fresh, correctly programmed 20791901 fuel system control module isn’t just a repair—it’s preventative maintenance against being stranded.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to download the latest, most specific software from GM and flash it directly onto your new module. It will arrive at your door ready for installation, with no further programming required.
Is this a difficult part to install?
For most vehicles, the installation is straightforward. The module is typically located on the vehicle’s frame rail (on trucks/SUVs) or in the trunk/rear compartment area (on cars). It’s usually held in place by a few bolts and has one electrical connector. Basic hand tools are all that’s required. However, we always recommend consulting a repair manual for your specific model or having a qualified mechanic perform the installation if you are not comfortable.
Will this fix my Check Engine Light for code P069E?
Yes, in the vast majority of cases, a faulty FSCM is the root cause of a P069E code. Replacing the old module with this new, properly programmed 20791901 fuel system control module is the correct procedure to resolve this specific code and extinguish the Check Engine Light.
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific vehicle. You can easily find it on your vehicle’s registration, your insurance card, or on the vehicle itself—either on a sticker in the driver’s side door jamb or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Are there any other parts I should replace at the same time?
While not always required, it’s a good practice to inspect the module’s electrical connector for any signs of corrosion or damage. If the connector is green, brittle, or has broken wires, it should be replaced to ensure a solid connection and prevent future issues.
