Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
As a technician with over two decades of experience, I’ve seen countless drivers spend a fortune replacing a perfectly good fuel pump when the real culprit was a failed Fuel System Control Module (FSCM). A customer’s 2011 Silverado 1500 came into my shop last week with the classic symptoms: it would crank but not start, and when it did run, it would stall unexpectedly at traffic lights. The owner was convinced his fuel pump was dead. After a quick scan, however, the real issue was a U0109 (Lost Communication with Fuel Pump Control Module) and a P069E code. The FSCM, exposed to years of road grime and moisture on the frame rail, had finally given up. This is a scenario I’ve diagnosed hundreds of times on vehicles just like yours.
Don’t make an expensive diagnostic mistake. This Fuel System Control Module is the direct, reliable solution to restore your vehicle’s performance and get you back on the road with confidence.
The Plug-and-Play Solution: No Dealer Visit Required
The biggest headache with replacing modern electronic modules is the need for expensive dealership programming. We eliminate that completely. Before this module ships, our technicians will flash it with the latest official GM software, specifically matched to your vehicle using the VIN you provide. 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 starts and then immediately stalls
- โ Stuttering or hesitation during acceleration
- โ Reduced engine power and “Service Engine Soon” light
- โ Diagnostic Trouble Codes (DTCs) like P069E, U0109, P0230, or P2635
Expert Pro Tip: Check Your Connections
Before installing your new module, take a moment to inspect the wiring harness connector. These FSCMs are often mounted on the frame rail, where they are exposed to water, salt, and dirt. I’ve seen many cases where corrosion on the connector pins was the root cause of the failure. Use a small wire brush and some electrical contact cleaner to ensure the pins are bright and clean. This simple step ensures a solid connection and prevents future issues.

Simple, DIY-Friendly Installation Guide:
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs (like the Silverado, Sierra, Tahoe, Yukon), the FSCM is mounted on the driver’s side frame rail, often near the spare tire. On cars (like the CTS or LaCrosse), it may be in the trunk or rear compartment.
- Swap the Part: Unplug the electrical connector and unbolt the old module from its mounting bracket. Secure the new module in its place and firmly reconnect the wiring harness.
- Reconnect and Start: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds to allow the system to initialize, then start your engine. Your problem should be resolved!
