Restore Your Truck’s Performance and Reliability
Is your 2010-2012 Chevrolet Colorado hesitating, stalling, or refusing to start? Before you condemn the fuel pump, the real culprit is often the Fuel System Control Module (FSCM). This vital component acts as the brain for your fuel delivery system, precisely managing the fuel pump’s voltage to ensure optimal engine performance and efficiency. When it fails, it can leave you stranded. This isn’t just an inconvenience; it’s a critical failure that can mimic a bad fuel pump, leading to misdiagnosis and wasted money on parts you don’t need.
We offer a dependable and straightforward solution. This is a genuine GM Fuel System Control Module, part number 20791901, that arrives at your door pre-programmed with the latest GM software updates. We flash the module specifically to your vehicle’s VIN, ensuring perfect communication and a true plug-and-play installation. This eliminates the expensive and time-consuming trip to the dealership for programming, saving you both time and money.
A Technician’s Notebook
I remember a 2011 Colorado that came into the shop on a tow truck. The owner was frustrated because he had just replaced the fuel pump himself, but the truck still wouldn’t run for more than a few seconds before sputtering out. He was getting a P069E code (Fuel Pump Control Module Requested MIL Illumination). We connected our diagnostic scanner and monitored the commanded vs. actual fuel pressure. The command was there, but the module wasn’t delivering the correct voltage to the new pump. The original FSCM, exposed to years of road grime and moisture on the frame rail, had failed internally. We installed one of our VIN-programmed modules, and the truck fired right up and idled perfectly. It’s a classic case where diagnosing the control side of the circuit saves you from replacing a perfectly good fuel pump.
Is Your Colorado Showing These Telltale Signs?
A failing FSCM can present a variety of symptoms. If you’re experiencing any of the following, this module is the likely solution for your 2010-2012 Colorado FSCM issues.
- âś” Engine cranks but will not start
- âś” Stalling, especially under load or when coming to a stop
- âś” Rough idle or engine hesitation during acceleration
- âś” Reduced engine power and poor fuel economy
- âś” Check Engine Light with codes like P069E, P0230, or U0109 (Lost Communication with FPCM)
A Straightforward Guide to Installation
Replacing the FSCM on your Colorado is a job most DIYers can handle with basic tools. The module is typically located on the vehicle’s frame rail, making it accessible. Follow these steps for a successful replacement.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the FSCM mounted to the rear center frame on your 2010-2012 Colorado. It’s a small silver box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note their orientation. Then, unbolt the module from the frame. These bolts can sometimes be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed FSCM into place. Ensure it is securely mounted.
- Reconnect: Plug the electrical connectors firmly into the new module. You should hear a click as they lock into place.
- Final Steps: Reconnect the negative battery terminal. Your vehicle is now ready to start with the new module fully integrated. No further programming is required.

Where is this module located on my 2011 Colorado?
On the 2010-2012 Chevrolet Colorado and GMC Canyon, the Fuel System Control Module (FSCM) is located on the outside of the frame, near the rear center of the vehicle. It’s typically mounted close to the spare tire area.
How do I know if I need a fuel pump or a fuel pump module?
It can be tricky as symptoms overlap. A good diagnostic step is to check for power at the fuel pump connector while a helper cranks the engine. If you have no or erratic voltage, the FSCM is the likely cause. Diagnostic trouble codes like U0109 (lost communication) or P069E point directly to the module, while a code like P0171 (System Too Lean) could be either.
