Is Your HUMMER Stalling, Hesitating, or Refusing to Start?
You turn the key, the engine cranks, but it just won’t catch. Or maybe it starts, but then sputters and dies unexpectedly at a stoplight. These are frustrating and potentially dangerous symptoms that I’ve seen countless times in my 20+ years as a technician. More often than not, especially on these GM platforms, the culprit isn’t the fuel pump you might suspect, but its electronic commander: the Fuel System Control Module (FSCM).
Real-World Diagnosis: “A customer’s 2010 Hummer H3 came in last week with these exact symptoms, along with a P069E trouble code. They had already replaced the fuel pump, but the problem remained. The FSCM, mounted on the rear frame rail and exposed to years of road grime and moisture, had failed internally. We installed one of our VIN-programmed modules, and the truck fired right up and ran perfectly. This is a fix I’ve performed hundreds of times, saving customers from unnecessary repairs.”
