Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
As a technician with over two decades of diagnostic experience, one of the most common issues I see on 2010-2012 GM vehicles is a sudden no-start or stalling condition, often accompanied by the dreaded P069E, P0230, or U0109 trouble codes. The culprit is very often a failed Fuel System Control Module (FSCM), also known as a fuel pump driver module. This small but critical component, typically mounted on the frame rail or in the trunk area, is responsible for regulating the voltage to your fuel pump. When it fails, your engine is starved of fuel, leaving you stranded.
Just last week, a customer’s 2011 Sierra 1500 was towed into my bay with these exact symptoms. The engine would crank but never fire up. A quick scan showed code P069E. After confirming power and ground to the module, we knew the FSCM itself had given up. These modules are exposed to harsh conditionsโwater, salt, and vibrationโwhich leads to internal electronic failure over time.
The Plug-and-Play Solution: A Pre-Programmed GM Fuel System Control Module
Don’t waste time and money at the dealership. This is a direct-replacement GM Fuel System Control Module that solves the problem without the hassle. The biggest challenge with replacing an FSCM has always been the required programming. A new module from the dealer is just a blank box; it won’t work until it’s programmed with expensive, specialized equipment. We eliminate that step entirely.
We flash this module with the latest GM-certified software, specifically matched to your vehicle’s VIN before we ship it. This means it arrives at your door ready for a simple, straightforward installation.
Common Symptoms of a Failing FSCM:
- โ Engine cranks but will not start
- โ Vehicle stalls while driving, especially under load
- โ Hesitation or stumbling on acceleration
- โ Check Engine Light with codes P069E, P0230, or U0109
- โ “Service Fuel System” message on the dash
- โ Inconsistent fuel pressure readings
Expert Pro Tip: Before installing your new module, take a moment to closely inspect the electrical connector and harness. On trucks like the Silverado and Sierra where the FSCM is mounted to the frame, I’ve seen countless cases where moisture intrusion has caused corrosion or even melted pins on the connector. Cleaning the connector with a contact cleaner and a small brush can prevent a repeat failure and ensure a solid connection for your new part.
Plug-and-Play Installation: No Dealer Visit Required
You can do this job in your own driveway with basic hand tools. While the exact location varies by model (check your service manual), the process is generally the same.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the FSCM: On most trucks and SUVs (Silverado, Tahoe, Escalade), it’s on the driver’s side frame rail, near the spare tire. On cars (CTS, LaCrosse), it’s often in the trunk or rear compartment.
- Disconnect and Remove: Unplug the electrical connector(s) and unbolt the old module from its mounting location.
- Install the New Module: Bolt your new, pre-programmed module in place and securely reconnect the electrical harness.
- Reconnect Battery: Reattach the negative battery terminal. The vehicle is now ready to start with no further programming needed.
