Restore Your Vehicle’s Performance and Reliability
Are you battling frustrating engine stalls, hesitation during acceleration, or a vehicle that simply won’t start? A faulty Fuel System Control Module (FSCM) is often the hidden cause behind these issues, frequently triggering diagnostic trouble codes like P069E, P2635, or P0230. This critical component regulates the voltage sent to your fuel pump, ensuring your engine receives the precise amount of fuel it needs. When it fails, it leaves you stranded. Get your vehicle running right again with our direct-fit, pre-programmed Fuel System Control Module.

Expert Insight: The Technician’s Perspective
As a technician, I’ve seen countless GM trucks and SUVs come in on a tow truck with a no-start condition caused by a failed FSCM. On many of these vehicles, the module is mounted to the frame rail, where it’s constantly exposed to road salt, water, and debris. This leads to corrosion that compromises the internal electronics. Our pre-programmed Programmed Fuel System Control Module 20850927 isn’t just a part; it’s a complete repair solution. It empowers both DIYers and professional shops to complete the job efficiently, correctly, and without the need for expensive dealer-specific scan tools. It’s the smartest way to get your vehicle back on the road.
Frequently Asked Questions
What does the Fuel System Control Module do?
The FSCM, also known as the Fuel Pump Control Module, acts as a smart controller for your vehicle’s fuel pump. Instead of the pump running at full speed all the time, the FSCM precisely regulates the voltage it receives based on engine demand. This ensures optimal fuel pressure, improves efficiency, and extends the life of the fuel pump.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). Our technicians will use this number to flash the module with the exact software calibration for your specific vehicle before we ship it.
Is this part really plug-and-play?
Yes. Because we program the module to your VIN before shipping, it is ready for installation right out of the box. Once installed, it will communicate correctly with your vehicle’s other computers, requiring no further calibration or dealer intervention. It’s a true plug-and-play solution.
Where is this module typically located on my vehicle?
Location varies by model. On many GM trucks and SUVs (like the Silverado, Tahoe, and Escalade), it’s mounted on the driver’s side frame rail, near the spare tire. On sedans and crossovers (like the Impala or Acadia), it can be found in the trunk area or near the rear crossmember. A quick search for your specific model will confirm the exact location.
Will this work if my original part number is different?
Yes, this module is a direct replacement for several part numbers, including 20791901, 20827745, and 20877116. As long as your vehicle is listed in our compatibility chart, this Programmed Fuel System Control Module 20850927 will function correctly once programmed to your VIN.
