Restore Power and Reliability to Your GM Truck
Is your 2010-2012 GMC Canyon or other GM vehicle suddenly stalling, struggling to start, or showing a ‘Reduced Engine Power’ message? Before you spend hundreds on a new fuel pump you might not need, the real problem could be a faulty Fuel System Control Module (FSCM). As the brain of your fuel delivery system, this module is critical for regulating fuel pressure. When it fails, it can cause a host of frustrating and potentially dangerous issues, often leaving you stranded.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and dealer expense out of the equation. Simply provide your vehicle’s VIN at checkout, and our technicians will program this module with the latest GM software updates specific to your truck. It arrives at your door ready to be installed, saving you from costly dealership programming fees and diagnostic headaches. This is the definitive fix for a wide range of fuel-related problems.
From the Diagnostic Bay: The Ghost in the Fuel System
I’ll never forget a 2011 Sierra that came into my shop. The owner was at his wit’s end. He had already replaced the fuel pump—twice!—but the truck would still randomly lose power and die on the highway. He was convinced he had a lemon. I hooked up my scanner and immediately saw DTC U0109, ‘Lost Communication with Fuel Pump Control Module.’ We weren’t talking to the FSCM. A quick check confirmed the module, exposed to the elements on the frame rail, had failed internally. We installed a new, pre-programmed FSCM, and the truck ran perfectly. It’s a classic case where the obvious part (the pump) isn’t the problem, and this simple module was the key to fixing it.
Is Your Truck Exhibiting These Telltale Signs?
A failing FSCM can mimic a bad fuel pump. If you’re experiencing any of the following, this module is the most likely solution:
- âś” Engine cranks but won’t start
- âś” Sudden stalling while driving
- âś” ‘Reduced Engine Power’ warning light
- âś” Check Engine Light (CEL) with specific codes
- âś” Common Diagnostic Trouble Codes (DTCs): P069E, P0230, U0109
- âś” Inconsistent or rough idling
A Straightforward Guide to Installation
For the handy DIYer or professional mechanic, installing this module is a simple process. On the 2010-2012 GMC Canyon, you’ll find it mounted to the frame. Always consult a service manual for your specific vehicle’s location.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs, the FSCM is mounted on the driver’s side frame rail, near the spare tire. On the Canyon, it’s typically on the rear center frame.
- Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle with the locking tabs. Then, unbolt the old module from the frame.
- Install the New Module: Bolt the new, pre-programmed FSCM into place and securely reconnect the electrical harnesses. You should hear a ‘click’ as they lock.
- Reconnect and Test: Reconnect the battery terminal. Prime the fuel system by turning the key to the ‘On’ position (without starting) for a few seconds, then turn it off. Repeat this 2-3 times. Start the engine and check for proper operation.

What does a Fuel System Control Module (FSCM) do?
What does a Fuel System Control Module (FSCM) do?
The FSCM, sometimes called a fuel pump driver module, acts as a smart relay for your fuel pump. It receives commands from the main engine computer (ECM) and precisely controls the voltage sent to the fuel pump. This ensures the engine gets the exact amount of fuel it needs under all conditions, improving efficiency and performance.
Is this part truly plug-and-play?
Yes! Because we program the module to your vehicle’s specific VIN before shipping, it is a 100% plug-and-play solution. You do not need a GM Tech 2 scanner or a trip to the dealership. Just install it, and you’re ready to go.
Where is the FSCM located on my 2011 GMC Canyon?
For the 2010-2012 GMC Canyon and its sibling, the Chevy Colorado, the FSCM is typically mounted on a crossmember of the frame at the rear of the vehicle, often near the spare tire.
Will this fix a check engine light with code P069E?
Yes, P069E (Fuel Pump Control Module Requested MIL Illumination) is one of the most common codes indicating a failed FSCM. Replacing the module is the standard, correct repair for this code.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We must have your VIN to program the module before we can ship your order.
