Is Your GM Truck or SUV Stalling or Refusing to Start?
If you’re dealing with frustrating issues like your engine cranking but not starting, sudden stalling while driving, or a persistent Check Engine Light with code P069E, the culprit is very likely a failed Fuel System Control Module (FSCM). As a mechanic with over two decades of experience, I’ve seen this exact scenario play out hundreds of times on vehicles like the Silverado, Sierra, Tahoe, and Escalade. The original FSCM is often mounted on the frame rail, where it’s constantly exposed to road salt, water, and vibration, leading to internal failure.
The Dealership-Free Solution: A Pre-Programmed GM FSCM Module
Don’t waste time and money on a trip to the dealership for diagnostics and programming. This is a direct-replacement Fuel System Control Module that solves the problem without the hassle. We take the complexity out of the repair by pre-programming this module specifically for your vehicle using your VIN. It arrives at your door loaded with the latest GM-approved software, making it a true plug-and-play solution. You get a reliable part that restores factory performance and communication, all without needing expensive scan tools or a tow truck.
Expert Pro Tip: The Connection is Key
Before you plug in your new FSCM, take a moment to inspect the vehicle’s wiring harness connector. Over the years, I’ve seen countless cases where dirt, moisture, and green corrosion build up inside the connector, causing poor contact and mimicking the symptoms of a bad module. Use a small brush and a quality electrical contact cleaner to thoroughly clean the pins and sockets. A clean connection is critical for ensuring the new module functions correctly and lasts for years to come.
Symptoms of a Failing FSCM:
- โ Engine cranks but will not start
- โ Vehicle starts and then immediately stalls
- โ Loss of power or hesitation during acceleration
- โ Reduced fuel economy
- โ Check Engine Light illuminated with code P069E (Fuel Pump Control Module Commanded OFF)
