Restore Your Vehicle’s Performance and Reliability
Is your 2012 Captiva Sport or other GM vehicle experiencing frustrating issues like stalling, extended cranking times, or a sudden loss of power? Before you condemn the fuel pump, the real culprit is often a failing Fuel System Control Module (FSCM). This critical component, also known as the fuel pump driver module, is the brain behind your fuel delivery system. When it fails, it starves your engine of the fuel it needs, leading to a host of performance problems and leaving you stranded. This isn’t just an inconvenience; it’s a safety concern.
We offer a dependable and straightforward solution: a replacement FSCM, part number 20877116, that arrives at your door fully programmed to your vehicle’s specific VIN. This means no expensive trip to the dealership for flashing or calibration. We handle the complex part, so you can get back on the road quickly and confidently. By installing our pre-programmed module, you are restoring the precise fuel pressure control your vehicle was designed with, ensuring optimal engine performance, fuel efficiency, and reliability.
A Technician’s Notebook: The Fuel Pump That Wasn’t the Problem
I once had a 2011 Silverado 1500 in my bay that was on its second new fuel pump in six months, but it still kept setting a P069E code (Fuel Pump Control Module Commanded On) and would intermittently stall. The owner was frustrated and out of money. Instead of throwing another pump at it, I went straight for the FSCM mounted on the frame rail. It was caked in dirt and road salt. After swapping it with a known-good unit, the truck ran perfectly. The original FSCM’s internal electronics had failed from corrosion and vibration, causing it to send erratic signals. This story is a classic example of why diagnosing the entire fuel control circuit, including the FSCM, is crucial. This pre-programmed module saves you from that diagnostic headache and repeat repairs.
Common Signs of a Failing FSCM
- ✔ Check Engine Light with codes such as P069E, P0230, or U0109 (Lost Communication With Fuel Pump Control Module).
- ✔ Engine stalls unexpectedly, especially under load or when coming to a stop.
- ✔ Vehicle cranks but refuses to start, or takes a very long time to fire up.
- ✔ Noticeable loss of engine power and poor acceleration.
- ✔ Rough or unstable idling.
- ✔ Inconsistent fuel gauge readings in some cases.
A Straightforward Guide to Installation
Installing your new FSCM is a manageable job for a confident DIYer or a quick task for any professional. While the exact location varies, this guide provides the general steps.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Module: On most trucks and SUVs (like the Silverado, Tahoe, Yukon), the FSCM is mounted on the driver-side frame rail, near the spare tire. On cars and crossovers (like the Captiva Sport, CTS, Impala), it’s often found in the trunk or rear compartment area, behind a trim panel.
- Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle with the locking tabs, as they can become brittle over time. Then, unbolt the old module from its mounting location.
- Install the New Module: Bolt the new, pre-programmed FSCM into place. Ensure it is securely fastened. Reconnect the electrical connectors, making sure they click firmly into place.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10-15 seconds (without starting the engine) to allow the system to initialize, then start your vehicle. The check engine light should be off, and your fuel delivery issues resolved.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN (Vehicle Identification Number) is required so we can program the module with the exact, most current GM software for your specific model, year, and options. This ensures perfect communication with your vehicle’s computer and avoids any compatibility issues.
Is this part ready to install out of the box?
Yes! Because we program it to your VIN before shipping, it is a true plug-and-play solution. No further programming or dealership visits are required. Just install it and you’re ready to go.
Will this fix a check engine light for code P069E?
In my 20+ years of experience, a faulty FSCM is the most common cause of a P069E code. While you should always perform a complete diagnosis, replacing a bad FSCM with this programmed unit will resolve that code in the vast majority of cases.
Where is the FSCM located on my 2012 Captiva Sport?
On the 2012 Chevrolet Captiva Sport, the Fuel System Control Module is typically located in the left-hand (driver’s side) rear compartment or trunk area, often behind an interior trim panel.
Is this the same as the fuel pump?
No. The fuel pump is the mechanical pump inside your fuel tank. This FSCM is the electronic module that controls the fuel pump, telling it how fast to run to maintain proper fuel pressure. They are two separate parts.
