Is Your GM Truck or SUV Suddenly Unreliable?
There’s nothing more frustrating than a vehicle that won’t start, stalls in traffic, or hesitates when you need power the most. If your Silverado, Tahoe, Escalade, or other GM vehicle is throwing fuel-related check engine lights or leaving you stranded, a failing Fuel System Control Module (FSCM) is a very likely culprit. This small but critical component regulates the voltage sent to your fuel pump, and when it fails, it can cause a cascade of baffling and stressful problems. Don’t waste money throwing parts at the problem—get the definitive solution right here.
Common Symptoms & Your Solution
A faulty FSCM can mimic a bad fuel pump, leading to incorrect and expensive repairs. Before you replace the pump, check if you’re experiencing any of these classic signs of a failing module:
- Engine cranks but won’t start
- Stalling, especially under load or when coming to a stop
- Rough idling or engine hesitation
- Reduced engine power and poor acceleration
- Check Engine Light with codes like P069E, P0230, or U0109 (Lost Communication with Fuel Pump Control Module)
This Programmed 20827745 Fuel System Control Module is the direct, reliable fix for these issues. We take all the guesswork and hassle out of the repair by pre-programming the unit to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means no expensive trips to the dealership for coding—it’s a true plug-and-play repair you can perform right in your driveway.

An Expert’s Note: The Hidden Cause of “No-Start” Conditions
I’ve seen it countless times in the shop: a customer comes in with a Silverado that has had two new fuel pumps installed by other shops, yet it still randomly stalls. The real issue wasn’t the pump, but the original FSCM failing under heat and vibration. These modules are often mounted on the frame rail, exposed to the elements, which leads to corrosion and internal failure. Our Programmed 20827745 Fuel System Control Module, flashed with the latest software updates from GM, often corrects drivability issues that the original software didn’t. It’s the fix that finally provides a permanent solution and gets that truck back to work reliably.
Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN is required so we can program the module with the correct software and calibrations for your specific engine, transmission, and options. This step ensures the module communicates perfectly with your vehicle’s other computers, making the installation truly plug-and-play.
Is this part difficult to install?
For most trucks and SUVs, the FSCM is located on the driver’s side frame rail, near the spare tire. It’s typically held on by a few bolts and has one electrical connector. For a DIYer with basic tools, it’s generally a straightforward repair that can be completed in under an hour. No special programming tools are needed since we handle that for you.
Will this fix a P069E trouble code?
Yes, the P069E code (Fuel Pump Control Module Requested MIL Illumination) is one of the most common indicators of a failing FSCM. Replacing your old module with this pre-programmed unit is the correct and most effective way to resolve this specific code.
What happens if I don’t replace a failing FSCM?
A failing FSCM will only get worse over time. Intermittent stalling can become a permanent no-start condition, leaving you stranded without warning. It can also put extra strain on your fuel pump. Replacing it proactively restores your vehicle’s dependability.
Is this compatible with part number 20791901?
Absolutely. This module is a direct, interchangeable replacement for several GM part numbers, including 20791901, 20877116, and 20850927. It will fit and function perfectly in any vehicle that calls for those parts.
