Restore Your Truck’s Power and Reliability
Is your 2010-2012 Silverado 1500 experiencing frustrating issues like stalling, long crank times, or a sudden no-start condition? Before you consider replacing the entire fuel pump, the problem often lies with a faulty Fuel System Control Module (FSCM). As a technician with over two decades of experience, I’ve seen countless trucks come into the shop with these exact symptoms. The FSCM is the brain that tells your fuel pump how much pressure to deliver. When it fails, it can starve your engine of fuel, leading to poor performance and leaving you stranded.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra costs out of the repair. Simply provide your vehicle’s VIN at checkout, and our experts will program this module with the latest, most stable software directly from GM. This means no expensive trip to the dealership for programming. You get a part that is truly plug-and-play, designed to restore your truck’s factory performance right out of the box. This is the definitive fix for a failing 2010-2012 Silverado FSCM.
A Technician’s Notebook: The $800 Misdiagnosis
A customer brought in his 2011 Sierra, completely frustrated. He had just spent over $800 at another shop to have a new fuel pump installed, but the truck still wouldn’t start. The check engine light was on with code P069E (Fuel Pump Control Module Commanded OFF). A quick check of the data stream showed the new pump was fine, but the FSCM wasn’t sending any commands. The original module, exposed to years of road salt and moisture on the frame rail, had failed internally. We installed one of our pre-programmed FSCMs, and the truck fired up on the first try. He could have saved himself hundreds of dollars and a major headache by diagnosing the FSCM first. It’s a lesson I share with every truck owner facing fuel delivery issues.
Is Your Silverado Showing These Signs?
A failing FSCM can mimic a bad fuel pump. Watch for these common indicators:
- âś” Engine stalls unexpectedly, especially under load or when coming to a stop.
- âś” Vehicle cranks but refuses to start.
- âś” Noticeable hesitation or sputtering during acceleration.
- âś” Reduced power and poor fuel economy.
- âś” Check Engine Light is illuminated with specific trouble codes. Common DTCs include P069E, P0230, P0627, and U0109 (Lost Communication with Fuel Pump Control Module).
A Straightforward Guide to Installation
Replacing the FSCM is a job most DIYers can handle in their own driveway. On most GM trucks and SUVs, it’s located on the driver’s side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FSCM mounted to the inside of the driver-side frame rail. You may need to lower the spare tire for better access.
- Disconnect Electrical Connectors: Carefully press the release tabs and pull the electrical connectors straight out. Do not pull on the wires. Inspect the connectors for any corrosion or damage.
- Remove Mounting Bolts: Use a socket wrench to remove the bolts securing the old module to the frame.
- Install the New Module: Mount your new, pre-programmed 2010-2012 Silverado FSCM in place and tighten the bolts securely.
- Reconnect Everything: Plug the electrical connectors back in until they click, and then reconnect your battery terminal.
- Final Check: Turn the key to the ‘On’ position for a few seconds to allow the system to prime, then start the engine. Your truck should now run smoothly.

Frequently Asked Questions
Do I really need to provide my VIN?
Yes, absolutely. Providing your VIN is essential. We use it to load the correct GM-certified software for your truck’s specific configuration. This step ensures perfect compatibility and prevents performance issues, making the installation truly plug-and-play.
Is this part difficult to install myself?
Not at all. For most DIYers with basic hand tools, this is a straightforward repair. The module is typically located on the driver’s side frame rail and is held on by a few bolts. Since our module comes pre-programmed, you save the hassle and expense of a dealership visit.
Will this fix a P069E trouble code?
A P069E code is one of the most common indicators of a failed FSCM. While you should always perform a proper diagnosis, in a vast majority of cases I’ve seen in my shop, replacing the FSCM with a properly programmed unit like this one is the correct and final repair.
Is this a new or used part?
This is a high-quality, tested, and verified used OEM part. We ensure each module is fully functional before programming it with the latest GM software for your vehicle. This provides OEM reliability without the high dealership price tag.
What is the difference between the FSCM and the fuel pump?
The fuel pump is a mechanical device inside your gas tank that moves fuel. The Fuel System Control Module (FSCM) is the electronic computer that tells the fuel pump how fast to run and how much pressure to create. A bad FSCM can make a good fuel pump seem like it has failed.
