Is Your Truck Stalling, Hesitating, or Refusing to Start?
A faulty Fuel System Control Module (FSCM) is one of the most common reasons for erratic engine behavior in GM trucks and SUVs. If you’re experiencing sudden stalls, poor acceleration, a persistent check engine light, or a no-start condition, the FSCM is the likely culprit. This isn’t just an inconvenience; it’s a critical failure that can leave you stranded. Don’t let a small electronic box dictate your day. Take control with a solution designed to get you back on the road quickly and reliably.
Common Symptoms & Your Solution
A failing FSCM can manifest in several ways, often triggering Diagnostic Trouble Codes (DTCs) like P069E, P0230, or P0606. You might notice your truck cranks but won’t start, idles roughly, or loses power unexpectedly while driving. This is because the module is failing to properly regulate the voltage to the fuel pump, starving your engine of the fuel it needs. Our programmed 20877116 fuel system control module is the definitive solution. We take a genuine OEM-quality module and flash it with the latest official GM software, tailored specifically to your vehicle’s Vehicle Identification Number (VIN). This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.

From the Technician’s Bench:
I’ve replaced hundreds of these modules over the years. On trucks like the Silverado and Sierra, they are typically mounted to the frame rail, exposed to everything the road throws at them—water, salt, mud, and vibration. This exposure is the number one killer of these components. The original modules can suffer from internal corrosion or circuit board failure, leading to intermittent problems that are a nightmare to diagnose. Installing our pre-programmed module isn’t just a repair; it’s a solid fix that ensures your fuel system’s electronic brain is fresh, updated, and ready for years of dependable service. It’s the fix I’d perform on my own truck.
Stop guessing and start fixing. By providing your VIN at checkout, you’re not just buying a part; you’re getting a complete, ready-to-install solution. Restore the power, reliability, and confidence you depend on from your vehicle. This is the most effective way to permanently resolve your fuel system issues and get your truck running like it should. Order your programmed 20877116 fuel system control module today.
Frequently Asked Questions
Why do I need to provide my vehicle’s VIN?
Your vehicle’s computer systems are designed to communicate only with modules programmed to its specific VIN. We flash this module with your unique VIN and the latest GM software to ensure it works seamlessly with your truck, preventing compatibility issues and error codes. It makes the installation plug-and-play.
Is this part difficult to install?
For most trucks and SUVs, the FSCM is located on the driver-side frame rail, making it accessible for a DIY mechanic with basic tools. It typically involves disconnecting the battery, unplugging the electrical connectors, and removing a few bolts. Since our module is pre-programmed, no special electronic tools are needed after installation.
Will this fix a P069E check engine light code?
Yes, the code P069E (Fuel Pump Control Module Commanded OFF) is one of the most common indicators of a failed FSCM. Replacing the faulty original with our correctly programmed module is the specific and reliable fix for this code.
What happens if I forget to provide my VIN after purchase?
We cannot ship your part until we have your VIN to program it. Our customer service team will contact you via email to request the information. Providing your VIN during checkout is the fastest way to get your order processed and shipped.
Is this the same as a Fuel Pump Driver Module?
Yes, Fuel System Control Module (FSCM) and Fuel Pump Driver Module (FPDM) are terms used interchangeably for the same component. This module controls the voltage sent to the fuel pump.
