Is your 2010-2012 Silverado 1500 suddenly stalling, struggling to start, or showing a check engine light? Before you condemn the fuel pump, the real culprit is often the Fuel System Control Module (FSCM). As a technician with over two decades of experience, I’ve seen this exact scenario countless times. The FSCM, also known as a fuel pump driver module, is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to frustrating and unpredictable performance issues.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine GM module and program it with the latest factory software specifically for your truck’s Vehicle Identification Number (VIN). This critical step means you can skip the expensive trip to the dealership for programming. You get a part that is truly plug-and-play, restoring your truck’s reliability and performance right out of the box.
A Technician’s Notebook
I remember a 2011 Sierra that came into the shop on a tow truck. The owner had already replaced the fuel pump himself, but the truck still wouldn’t run for more than a few seconds before sputtering out. He was convinced he got a bad pump. After a quick scan, I found code P069E – ‘Fuel Pump Control Module Commanded On’. The FSCM wasn’t sending the right signals. These modules are mounted on the frame rail, exposed to water, salt, and vibrations, which causes internal corrosion. We installed one of our pre-programmed FSCMs, and the truck fired right up and ran perfectly. He could have saved himself a full day and the cost of a fuel pump by starting with the module.
Is Your Truck Showing These Symptoms?
A failing FSCM can mimic a bad fuel pump. Look for these common warning signs before you start tearing into the fuel tank. This module is often the solution for:
- ✔ Engine stalling, especially under load or when coming to a stop
- ✔ Extended cranking time or a no-start condition
- ✔ Rough idling and hesitation during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes like P069E, P0230, or U0109 (Lost Communication With FSCM)
A Straightforward Guide to Installation
Replacing the FSCM on your GM truck or SUV is a job most DIYers can handle in under an hour with basic hand tools. Our pre-programmed module makes it even simpler.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks like the Silverado and Sierra, you’ll find the FSCM mounted to the driver’s side frame rail, typically near the spare tire.
- Disconnect and Remove: Unplug the electrical connector(s) by depressing the locking tab. Then, remove the bolts or nuts holding the old module to the frame.
- Install the New Module: Bolt the new, pre-programmed FSCM into place. Be careful not to overtighten the fasteners.
- Connect and Finalize: Plug the electrical connector(s) firmly into the new module until they click. Reconnect your battery terminal. Your installation is complete! No programming is required.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN is required to program the module with the correct GM software and calibrations for your specific engine, transmission, and options. This ensures perfect compatibility and plug-and-play installation.
Is this part difficult to install?
Not at all. For most trucks, it’s held on by two or three bolts on the frame rail. With basic hand tools, the average DIY mechanic can replace it in under an hour. Since it comes pre-programmed, there are no complicated computer steps.
What happens if I install it without programming?
An unprogrammed module will not communicate correctly with your vehicle’s other computers, like the ECM. This will result in a no-start condition and communication error codes. Our service eliminates this problem entirely.
Will this fix a P069E code?
Yes, in a vast majority of cases, a faulty FSCM is the direct cause of a P069E code. This module is the most common and effective fix for that specific diagnostic trouble code.
Is this a new or used part?
This is a high-quality, inspected used OEM part that has been tested and prepared with fresh, vehicle-specific programming. It provides the same reliability as a new dealer part at a fraction of the cost.
