Restore Your Vehicle’s Fuel System Performance
Is your GM truck, SUV, or car suddenly stalling, refusing to start, or showing a check engine light with codes like P069E? Before you spend a fortune on a new fuel pump, the real problem is often a faulty Fuel System Control Module (FSCM). As a technician with over 20 years of experience, I’ve seen this exact scenario hundreds of times. This module is the brain that tells your fuel pump how much pressure to deliver. When it fails, it starves the engine of fuel, leading to frustrating and unreliable performance.
This isn’t just a replacement part; it’s a complete solution. We take a genuine GM module and program it with the very latest official software updates specifically for your vehicle’s VIN. This crucial step, which would normally require an expensive trip to the dealership, is done for you before we ship. The result is a reliable, plug-and-play fix that often corrects the original factory software flaws that led to the failure in the first place. By installing our Programmed GM FSCM, you’re not just fixing a symptom—you’re ensuring the long-term health and reliability of your vehicle’s fuel delivery system.
Case Study: The Silverado That Wouldn’t Start
A customer brought in their 2011 Silverado 1500. It would crank but not start, and they had already been told they needed a new fuel pump—a costly, labor-intensive job. I hooked up my scan tool and immediately saw code P069E (Fuel Pump Control Module Commanded OFF). Instead of dropping the fuel tank, I checked the FSCM, which is conveniently located on the frame rail. I found corrosion on the connector, a classic sign of failure. We swapped in a pre-programmed module, cleared the codes, and the truck fired right up. The customer saved over $700 and hours of downtime by correctly diagnosing the FSCM first.
Is Your GM Vehicle Showing These Symptoms?
A failing FSCM can mimic a bad fuel pump. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly while driving
- ✔ Hesitation or stumbling on acceleration
- ✔ Reduced engine power and performance
- ✔ Check Engine Light with DTCs such as P069E, P0230, or U0109
A Straightforward Guide to Your FSCM Swap
Installing your new Programmed GM FSCM is a job most DIYers can handle in under an hour. While the exact location varies slightly by model, the process is generally the same.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs (Silverado, Tahoe, Escalade), the FSCM is mounted to the driver’s side frame rail, near the spare tire. On cars and crossovers (CTS, Acadia, Vue), it may be in the trunk area or on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle with the locking tabs. Then, remove the bolts or nuts holding the old module in place.
- Install the New Module: Bolt the new, pre-programmed module into the same location. Ensure it is securely mounted.
- Reconnect: Plug the electrical connectors firmly into the new module. You should hear a click as they seat.
- Final Steps: Reconnect the battery terminal. Turn the key to the ‘On’ position for 10 seconds (without starting) to allow the system to initialize, then start the engine. Your vehicle is ready to go!

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. This is the biggest benefit we offer. We program the module to your vehicle’s specific VIN before we ship it, so it arrives ready for a simple, plug-and-play installation. This saves you time and the high cost of dealership programming.
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 this information.
Is this the same as the fuel pump?
No. This is the Fuel System Control Module (FSCM), which is the electronic controller that tells the fuel pump (located in the fuel tank) what to do. A faulty FSCM is a very common point of failure and is much easier and cheaper to replace than the entire fuel pump assembly.
Where is the FSCM located on my 2010 Saturn Vue?
On the 2010 Saturn Vue, the Fuel System Control Module is typically located in the right-hand rear of the engine compartment. Always confirm the location on your specific vehicle before starting the repair.
Will this fix a P069E check engine light code?
Yes, in the vast majority of cases, a faulty FSCM is the direct cause of a P069E code. Replacing it with our pre-programmed module is the correct and reliable fix for this issue.
