Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If your 2010-2012 GM vehicle is suddenly leaving you stranded, the issue might not be the fuel pump you just replaced. It’s a scenario I’ve seen countless times in my 20+ years in the garage. A customer’s 2011 Silverado 1500 was towed in last week with a classic crank-no-start condition. They had already spent hundreds on a new fuel pump, but the problem persisted. A quick scan with my tool revealed the real culprit: a P069E trouble code, pointing directly to a failed Fuel System Control Module (FSCM). This small but critical component, often called a fuel pump driver module, is the brain that tells the fuel pump how much pressure to deliver. When it fails, your engine gets starved of fuel.
The Direct Solution: A VIN-Programmed GM Fuel Control Module
Don’t waste time and money chasing the wrong parts or paying for expensive dealership programming. This Fuel System Control Module is the definitive, hassle-free solution. We take care of the most difficult part for you. Before we ship it, our technicians will program the module with the latest GM software, perfectly matched to your vehicle’s specific Vehicle Identification Number (VIN). This means it arrives at your door ready for a true plug-and-play installation.
Expert Pro Tip: Check Before You Replace
Before installing your new module, take a moment to inspect the electrical connector and harness. These modules are often mounted on the frame rail, exposed to the elements. I’ve seen cases where corrosion on the connector pins was the root cause of the intermittent signal. A quick cleaning with a contact cleaner can prevent future issues and ensure a solid connection for your new part.
Symptoms of a Failing FSCM:
- โ Engine cranks but will not start
- โ Stalling while driving, especially under load
- โ Rough idle or engine hesitation
- โ Reduced engine power and poor acceleration
- โ Check Engine Light with codes like P069E, P0230, or U0109
Plug-and-Play Installation: No Dealer Visit Required
You can perform this repair right in your driveway. While the exact location varies by model (check your service manual), the process is straightforward.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs (Silverado, Sierra, Tahoe, Yukon), it’s mounted on the driver’s side frame rail. On other vehicles (CTS, LaCrosse, Acadia), it may be in the trunk or on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connector. Then, remove the bolts or nuts holding the old module in place.
- Install the New Module: Mount your new, pre-programmed module and securely tighten the fasteners.
- Reconnect and Test: Plug the electrical connector back in, ensuring it clicks into place. Reconnect the battery terminal. Turn the key to the ‘On’ position for a few seconds to prime the system before starting the engine.
