Is Your GM Truck or SUV Stalling, Hesitating, or Not Starting?
If you’re dealing with frustrating fuel delivery issues in your Silverado, Tahoe, Escalade, or other GM vehicle, the problem is often not the fuel pump itself, but its electronic brain: the Fuel Pump Control Module (FPCM). As a mechanic with over two decades of experience, I’ve seen hundreds of these cases. A vehicle comes in with a no-start condition or stalls randomly, especially when it’s warm. The owner has often already replaced the fuel pump, only to find the problem persists. The real culprit is frequently this small but critical module.
The Real Problem: A Faulty Fuel Pump Control Module
The FPCM, also known as a Fuel System Control Module (FSCM), regulates the voltage sent to your fuel pump. This ensures precise fuel pressure for optimal performance and efficiency. Unfortunately, on many GM trucks and SUVs, these modules are mounted on the frame rail, where they are constantly exposed to water, road salt, and vibrations. This exposure leads to internal corrosion and failure, causing a range of confusing symptoms.
Common Symptoms of a Failing FPCM:
- โ Engine cranks but won’t start
- โ Vehicle stalls unexpectedly, especially when warm or under load
- โ Loss of power and hesitation during acceleration
- โ Rough or unstable idle
- โ Check Engine Light with codes like P069E, P0230, or U0109 (Loss of Communication with FPCM)
A Real-World Scenario from My Shop
A customer’s 2008 Sierra 1500 came in on a tow truck last month. It would start cold but die within 10 minutes and refuse to restart. There was no fuel pressure at the rail during the no-start condition. Instead of immediately condemning the new fuel pump the owner had just installed, we went straight to the FPCM on the driver’s side frame rail. The module’s casing was corroded, and the connector pins were green with oxidation. After replacing it with a pre-programmed unit like this one and cleaning the connector, the truck fired right up and ran perfectly. Always check the module and its connector firstโit can save you hundreds on an unnecessary fuel pump replacement.
The Solution: A VIN-Programmed 2008-2009 GM Fuel Pump Module
Skip the dealership’s high costs and long wait times. This FPCM is the direct, reliable solution you need. We take the hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. It arrives at your door loaded with the latest GM software updates, ready for a straightforward installation. This isn’t just a replacement part; it’s a complete, ready-to-install fix.
Plug-and-Play Installation: No Dealer Visit Required
- Safety First: Disconnect the negative battery terminal.
- Locate the Module: Find the old FPCM. On most trucks/SUVs, it’s on the driver-side frame rail near the spare tire. On other models (like the Traverse or Vue), check the rear crossmember or engine compartment as noted in the fitment list.
- Disconnect and Remove: Unplug the electrical connector and unbolt the old module from the frame. Be sure to inspect and clean the vehicle-side connector for any corrosion.
- Install the New Module: Bolt the new, pre-programmed module in place and securely reconnect the electrical harness.
- Final Steps: Reconnect the battery terminal. Your vehicle is now ready to start with its fuel system functioning correctly.

Frequently Asked Questions (FAQ)
Q: What does a Fuel Pump Control Module (FPCM) do?
A: The FPCM acts as a smart relay for your fuel pump. It receives commands from the main engine computer (ECM) and precisely controls the speed of the fuel pump to maintain optimal fuel pressure, improving both performance and fuel economy.
Q: How do I know if my FPCM is bad and not my fuel pump?
A: Common signs of a bad FPCM include intermittent stalling, a no-start condition even with a new pump, and specific diagnostic codes like P069E or U0109. A mechanic can test for voltage at the fuel pump connector; no voltage when the key is on often points to a failed FPCM.
Q: Is programming really necessary for this part?
A: Yes, absolutely. The FPCM must be programmed with your vehicle’s VIN to communicate correctly with the other computer systems on your vehicle. Our service eliminates this step for you, so the part is ready to install out of the box.
Q: Where is the FPCM located on my 2008 Silverado?
A: On most GM trucks from this era, including the 2008 Silverado, the FPCM is mounted to the inside of the driver-side frame rail, typically above or just forward of the spare tire. It’s held in place by a few bolts.
Q: What information do you need from me?
A: After you place your order, we just need your 17-digit Vehicle Identification Number (VIN). This allows us to load the correct, most up-to-date GM software for your specific vehicle configuration.
