Restore Your Vehicle’s Performance and Reliability
Are you battling frustrating engine stalls, a no-start condition, or a persistent Check Engine Light? A faulty Fuel System Control Module (FSCM) is often the culprit, disrupting the critical communication between your engine’s computer and the fuel pump. This can lead to poor performance, hesitation on acceleration, and leave you stranded. Get your truck, SUV, or sedan running dependably again with this direct-fit, pre-programmed fuel system control module.
Common Symptoms of a Failing FSCM & Your Direct-Fit Solution
If you’re experiencing any of the following issues, a failing FSCM is a likely cause. This module is the definitive solution, designed to resolve these problems and restore proper function.
- Unexpected engine stalling, especially while driving

Expert Insight from a 20-Year Technician:
Many of these FSCMs are mounted on the vehicle’s frame rail, where they are constantly exposed to water, salt, and road debris. Over time, this exposure can cause corrosion and internal failure of the circuit board. When it fails, the fuel pump doesn’t get the correct voltage command and your engine starves for fuel. We’ve seen countless vehicles towed in with a no-start condition that was fixed in minutes with a new module. The key, however, is programming. An unprogrammed module is just a metal box. By sending you a Programmed 20877116 Fuel System Control Module, we’re saving you the headache and cost of a tow bill and dealer labor fees. It’s the way I’d fix my own truck.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) is essential because every GM vehicle has specific software parameters. We use your VIN to load the exact, correct software and the latest updates from GM onto the module. This ensures it communicates perfectly with your Engine Control Module (ECM) and other vehicle systems, preventing compatibility issues.
Is this a true plug-and-play part?
Yes. Because we program the module to your VIN before shipping, the installation process is straightforward. You simply need to disconnect the electrical connectors and mounting hardware from your old module and install this one in its place. No further programming or calibration is required.
Where is the FSCM located on my vehicle?
On most trucks and SUVs like the Silverado, Tahoe, and Escalade, the FSCM is typically mounted on the driver’s side frame rail, often near the spare tire. On other vehicles like the Enclave or Traverse, it may be on a rear crossmember. Always consult a service manual for your specific model to confirm the exact location before beginning the repair.
What happens if I install a module that isn’t programmed?
An unprogrammed or incorrectly programmed module will not work. The vehicle will likely not start at all, or it may run very poorly. It will set communication-related trouble codes because it cannot properly ‘talk’ to the rest of the vehicle’s computer network. Our pre-programming service eliminates this entire problem.
Is this part difficult to replace myself?
For someone with basic mechanical skills and tools, this is a very manageable job. The most difficult part is often accessing the module on the frame rail. Once accessed, it’s typically held on by a few bolts and has one or two electrical connectors. The key is that our Programmed 20877116 Fuel System Control Module removes the most complex step: the computer programming.
