Is Your Silverado 1500 Stalling or Refusing to Start? The Problem Might Not Be Your Fuel Pump.
If your 2010-2012 Silverado 1500 is experiencing frustrating issues like intermittent stalling, extended cranking times, or a complete no-start condition, your first thought might be a bad fuel pump. But before you spend the time and money on that intensive repair, you need to look at a much more common culprit: the Fuel System Control Module (FSCM).
As a technician with over two decades of experience, I’ve seen this exact scenario play out hundreds of times. The FSCM, often called a fuel pump driver module, is the electronic brain that tells the fuel pump how much voltage to use. Because GM mounted these modules on the driver’s side frame rail, they are constantly exposed to water, salt, and road debris. This exposure leads to corrosion on the circuit board, causing erratic performance and eventual failure.
Real-World Diagnosis: A Technician’s Experience
“A customer’s 2011 Silverado 1500 came in last week with a classic P069E trouble code stored in the computer. The engine would crank all day but wouldn’t fire up. He had already replaced the fuel pump himself, but the problem persisted. The real culprit was the original FSCM, its aluminum housing corroded and its internal electronics compromised. A new, programmed module had him back on the road in under 30 minutes. It’s a textbook failure for these trucks.”
