Restore Your Vehicle’s Performance and Reliability
Is your GM vehicle stalling, hesitating, or refusing to start? A faulty Fuel System Control Module (FSCM) is often the culprit. As a technician with over 20 years of experience, I’ve seen countless drivers replace their fuel pump only to find the problem persists. The issue is frequently this critical module, which regulates voltage to the pump. This replacement FSCM, part number 20877116, is the definitive solution to restore proper fuel delivery and engine performance.
The biggest advantage we offer is that this module arrives at your door pre-programmed to your vehicle’s specific VIN. Simply provide us with your VIN after purchase, and we’ll flash the module with the latest GM software updates. This means no expensive trips to the dealership, no special programming tools required, and no headaches. It’s a true plug-and-play fix that gets you back on the road fast.
Case Study: A Tricky Diagnosis
I remember a 2011 Sierra 1500 in my bay that had its owner completely stumped. The truck would run fine for a while, then suddenly lose power and stall at a stoplight. He had already replaced the fuel pump, but the intermittent issue remained. After connecting my scan tool, I found a stored code: P069E – Fuel Pump Control Module Requested MIL Illumination. Instead of just throwing another part at it, we checked the FSCM, which is mounted on the frame rail. It showed signs of corrosion from road salt and moisture. We installed one of our VIN-programmed modules, and the truck has been running perfectly ever since. It’s a classic example of how diagnosing the complete system saves time and money.
Is Your GM Vehicle Showing These Fuel System Red Flags?
A failing FSCM can manifest in several ways. If you’re experiencing any of these, this module is the likely solution for your 2012 Captiva Sport FSCM or other compatible models.
- ✔ Engine cranks but won’t start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Hesitation or sputtering during acceleration
- ✔ Reduced engine power and poor performance
- ✔ Inconsistent fuel gauge readings
- ✔ Check Engine Light with codes like P069E, P0230, or U0109 (Loss of Communication with Fuel Pump Control Module)
A Straightforward Guide to Installation
Installing your new FSCM is a job most DIYers can handle with basic tools. The location varies slightly by model, but it’s generally accessible. For many trucks and SUVs, it’s on the driver’s side frame rail. For cars, it might be in the trunk or rear compartment.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Module: Find the old FSCM. On a 2012 Captiva Sport, it’s typically in the LH rear compartment. On a Silverado or Sierra, check the LH frame rail near the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, unbolt the module from its mounting location. These bolts can be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed FSCM into place. Ensure it’s secure to prevent issues from vibration.
- Reconnect and Finalize: Plug the electrical connectors firmly into the new module. Reconnect your battery terminal.
- Start the Vehicle: Turn the key to the ‘On’ position for a few seconds to let the system prime, then start the engine. Your fuel delivery issues should be resolved.

Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to program the module with the exact software and calibrations your vehicle requires from the factory. This ensures perfect communication with your vehicle’s other computers, like the ECM, and guarantees seamless, plug-and-play operation without a trip to the dealer.
Is this part difficult to install?
Not at all. For most DIYers with basic hand tools, this is a straightforward repair. The module is typically held on by a few bolts and has simple electrical connectors. Since we program it for you, the most complex part of the job is already done.
What’s the difference between this and a used part from a junkyard?
A used module will be programmed for the vehicle it came from, which will cause communication errors and running issues in your vehicle. Furthermore, it carries the same risk of failure as your old one. Our module is tested, confirmed functional, and programmed with the latest software for YOUR specific vehicle, ensuring reliability.
Will this fix a P069E code?
Yes, in the vast majority of cases, a faulty FSCM is the direct cause of a P069E trouble code. Replacing the module with this pre-programmed unit is the correct and most common repair for this specific code.
