Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If you’re dealing with frustrating fuel delivery problems in your 2010-2012 GM vehicle, the culprit is often a failed Fuel System Control Module (FSCM). I’ve seen it hundreds of times in my 20+ years as a technician. A vehicle gets towed in, the owner has already replaced the fuel pump, but the engine still cranks without starting or dies intermittently. A quick scan reveals a tell-tale code like P069E, P0230, or U0109, pointing directly to a communication or command failure with the FSCM.
From the Shop Floor: A Real-World Scenario
“A customer’s 2011 Sierra 1500 came in last week with these exact symptoms. It would stall randomly at red lights and was hard to start in the morning. He was convinced it was the fuel pump. But after confirming good fuel pressure at the rail, we checked the FSCM, which is mounted on the driver-side frame rail. It was corroded from years of exposure to road salt and moisture. The internal electronics had failed, preventing it from properly commanding the new fuel pump he had just installed. Replacing the FSCM with a correctly programmed unit solved the problem instantly.”
