Is Your Truck or SUV Stalling or Refusing to Start?
As a mechanic with over two decades of experience, I’ve seen countless GM trucks and SUVs towed into the shop with the same frustrating symptoms: the engine cranks perfectly but won’t fire up, or it dies unexpectedly while driving. The owner has often already spent money on a new fuel pump, only to find the problem persists. More often than not, the culprit is a failed Fuel System Control Module (FSCM), and the diagnostic scanner usually shows the tell-tale code P069E (Fuel Pump Control Module Commanded OFF).
This module is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to serious drivability and reliability issues. The factory-installed units, especially on trucks and SUVs, are often mounted on the frame rail, where they’re constantly exposed to water, road salt, and vibrations, leading to premature failure.
The Dealership-Free Solution: A Pre-Programmed FSCM Module
Traditionally, replacing an FSCM meant buying the part and then paying a dealership an hour or two of labor to program it to your vehicle. We eliminate that expensive and time-consuming step. This FSCM arrives at your door fully programmed with the latest GM software, specifically matched to your vehicle’s VIN. It’s a true plug-and-play solution that gets you back on the road fast.
Expert Pro Tip: Check Your Connectors
Before you install your new FSCM, take a close look at the vehicle’s wiring harness connector. I’ve seen modules condemned when the real issue was corrosion on the connector pins causing a poor connection. Use a small brush and a quality electrical contact cleaner to scrub away any green or white residue. Ensuring a clean, tight connection is a five-minute step that guarantees your new module can communicate properly from the start.
Common Symptoms of a Failing FSCM:
- โ Engine cranks but will not start
- โ Vehicle stalls intermittently, especially under load
- โ “Reduced Engine Power” message on the dashboard
- โ Check Engine Light with codes like P069E, P0230, or P0606
- โ Inconsistent fuel pressure readings
Simple, Direct-Fit Installation
You don’t need to be a master technician to replace this part. With basic hand tools, you can have your vehicle running in under an hour. Our VIN programming makes the electronic side of the job completely hands-off.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs (like the Silverado, Sierra, Tahoe), the FSCM is mounted to the driver’s side frame rail, near the spare tire. On cars (like the CTS or LaCrosse), it’s often in the trunk or rear compartment.
- Disconnect and Remove: Unplug the electrical connector and unbolt the old, faulty module from its mounting point.
- Install the New Module: Bolt your new, pre-programmed FSCM into place.
- Reconnect: Firmly plug in the electrical connector until it clicks. Reconnect the negative battery terminal.
- Start Your Engine: The job is done. No programming or relearn procedure is required.
