Restore Your Truck’s Performance and Reliability
There’s nothing more frustrating than a truck that won’t start, stalls unexpectedly, or hesitates when you need power the most. If your 2010-2012 Chevrolet Colorado is letting you down, the culprit is often a faulty Fuel System Control Module (FSCM). This small but critical component acts as the brain for your fuel pump, regulating its voltage to deliver the precise amount of fuel your engine needs. When it fails, it can cause a cascade of problems that leave you stranded.
As a technician with over two decades of experience, I’ve seen countless vehicle owners replace their fuel pump, only to find the problem persists. The issue wasn’t the pump; it was the module controlling it. This module is the definitive solution, arriving at your door pre-programmed with the latest GM software specifically for your truck’s VIN. You get a reliable, plug-and-play fix without the expensive trip to the dealership for programming.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2011 Colorado that came into the shop with a classic intermittent no-start. The owner had already replaced the battery and the fuel pump himself, but the truck would still randomly refuse to start, usually after being driven for a while. It wasn’t throwing consistent codes, just an occasional U0109 (Lost Communication with FSCM). We checked fuel pressure, and it was erratic. Instead of guessing, we monitored the voltage going to the pump directly from the FSCM. On a cold start, it was perfect. After a 20-minute drive, the voltage would drop to near zero, starving the engine. The module, mounted on the frame rail, was getting heat-soaked and failing internally. A new, properly programmed 2010-2012 Colorado Fuel Module solved the problem for good. It’s a textbook example of why diagnosing the entire system is key.
Is Your Truck Showing These Symptoms?
A failing FSCM can mimic other fuel system problems. Here are the most common signs that point directly to this module:
- ✔ Engine cranks but won’t start, or has a very long crank time.
- âś” Sudden stalling while driving, often without warning.
- âś” Vehicle hesitation or sputtering during acceleration.
- âś” Noticeable decrease in fuel economy.
- âś” Check Engine Light illuminated with common DTCs like P069E, U0109, P0230, or P025A.
A Straightforward Guide to Installation
Replacing the FSCM on your Colorado is a job most DIYers can handle with basic tools. This module is typically located on the rear center frame crossmember.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Module: Find the FSCM mounted to the frame rail or crossmember near the spare tire. It’s a small, finned aluminum box with electrical connectors.
- Disconnect Wiring: Carefully press the locking tabs and unplug the electrical connectors from the old module. Inspect the connectors for any corrosion or damage.
- Remove Old Module: Unbolt the module from the frame. These bolts can sometimes be rusty, so a little penetrating oil can be helpful.
- Install New Module: Bolt the new, pre-programmed FSCM into place. Ensure it is mounted securely.
- Reconnect and Test: Plug the electrical connectors firmly into the new module. Reconnect your battery, cycle the key a few times to prime the fuel system, and start the engine.

Frequently Asked Questions
What exactly does a Fuel System Control Module do?
The FSCM, or fuel pump driver module, controls the voltage sent to the electric fuel pump. Instead of the pump running at full speed all the time, the FSCM adjusts its speed based on engine demand. This provides more accurate fuel pressure, improves pump life, and enhances fuel efficiency.
Is this module truly plug-and-play?
Yes! We program the module to your vehicle’s specific VIN before shipping it. This means you can install it yourself without needing a trip to the dealer for expensive programming or calibration. It’s ready to install right out of the box.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive the VIN to ensure correct programming.
Will this fix a P069E trouble code?
Yes, in the vast majority of cases. The code P069E (Fuel Pump Control Module Requested MIL Illumination) is a very strong indicator that the FSCM itself has detected an internal fault and needs to be replaced.
Where is this located on my 2011 Colorado?
On the 2010-2012 Chevrolet Colorado and GMC Canyon, the FSCM is typically mounted on the rear frame crossmember, often near the spare tire.
