Is Your Silverado Stalling or Refusing to Start?
There’s nothing more frustrating than a truck that won’t run right. If your 2010-2012 Silverado 1500 is experiencing sudden stalling, hesitation under load, or a complete no-start condition, a faulty Fuel System Control Module (FSCM) is a very common cause. This small but critical component, often called the fuel pump driver module, is responsible for managing the voltage sent to your fuel pump. When it fails, it can starve your engine of fuel, leaving you stranded.
Over my 20+ years in the shop, I’ve seen these modules fail countless times, especially on GM trucks. They’re typically mounted on the frame rail, exposed to water, salt, and road debris, which leads to corrosion and internal failure. The symptoms can often be mistaken for a bad fuel pump, leading to expensive and unnecessary repairs.

Expert Pro Tip: Check Your Ground Connection!
Before you install your new FSCM, take a moment to inspect the ground wire. On these trucks, it’s a black wire bolted directly to the frame near the module. I’ve seen dozens of cases where a corroded or loose ground causes the exact same symptoms as a failed module. Clean the contact point on the frame with a wire brush until it’s shiny metal. This simple step ensures the new module functions correctly and can prevent premature failure.
Common Symptoms of a Failing FSCM:
- โ Engine cranks but will not start
- โ Stalling, especially when warm or under load
- โ Rough idle and poor engine performance
- โ Reduced power and hesitation during acceleration
- โ Check Engine Light with codes like P069E, P0230, or P0606

- Safety First: Disconnect the negative terminal from your truck’s battery.

- Disconnect and Remove: Unplug the two electrical connectors. Be gentle with the locking tabs. Then, remove the bolts holding the module to the frame.
