Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If your Chevrolet, GMC, Cadillac, or Hummer is experiencing frustrating fuel delivery problems, a faulty Fuel Pump Control Module (FPCM) is a very likely culprit. This critical component, also known as a Fuel System Control Module (FSCM), is responsible for precisely managing the voltage sent to your vehicle’s fuel pump. Unlike older systems that ran the pump at full speed constantly, modern GM vehicles use this module to vary the pump’s speed based on engine demand. This provides better efficiency and longevity, but when the module fails, it can leave you stranded. This replacement GM Fuel Pump Module is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a 2008 Silverado 1500 come into the shop that was on its third in-tank fuel pump in a year. The customer was frustrated, having spent a fortune on parts and labor. The truck would run fine for a few weeks, then start to hesitate under load and eventually fail to start. The previous shops kept pulling a low fuel pressure code and replacing the pump. We looked deeper. A quick visual inspection under the truck revealed the FPCM mounted to the frame rail, covered in white, chalky corrosion. We tested the power and ground going into the module—all good. But the voltage coming out to the pump was erratic and weak. The corroded module was overheating and failing intermittently, starving the engine of fuel. We installed a new, programmed FPCM, and the truck has run flawlessly ever since. It’s a classic case of misdiagnosis that could have been avoided by checking the FPCM first.
Common Symptoms of a Failing FPCM
- ✔ Engine Stalling: The engine may stall unexpectedly while driving or idling, often without warning.
- ✔ No-Start Condition: You may hear the engine crank, but it will not start due to a lack of fuel pressure.
- ✔ Hesitation or Stumbling: The vehicle may hesitate or stumble during acceleration as the module fails to command adequate fuel flow.
- ✔ Reduced Engine Power: The vehicle may enter a ‘limp mode’ with a significant loss of power to protect the engine.
- ✔ Check Engine Light: A failing FPCM will almost always trigger the Check Engine Light with specific Diagnostic Trouble Codes (DTCs). Common codes include P069E, P0230, P0627, and U0109.
- ✔ Long Crank Times: The engine may take longer than usual to start as the module struggles to build initial fuel pressure.
The Right Part, Programmed and Ready to Install
Replacing a failed FPCM isn’t just about swapping the hardware. These modules are intelligent components that communicate with your vehicle’s Powertrain Control Module (PCM). For them to function correctly, they must be programmed with the latest GM software specific to your vehicle’s Vehicle Identification Number (VIN). This listing eliminates the biggest headache of this repair: the programming. We handle it for you.
Simply purchase this module and provide us with your VIN. Our technicians will flash the unit with the correct, updated calibration for your exact vehicle. This means no expensive trip to the dealership for programming. When the part arrives at your door, it is ready for a direct, plug-and-play installation. This is the most efficient and cost-effective way to get your truck or SUV back on the road.

Frequently Asked Questions
Why does this module need to be programmed to my VIN?
The Fuel Pump Control Module communicates with other computers in your vehicle. VIN-specific programming ensures it has the correct software and calibration to manage your fuel system according to factory specifications for your exact make, model, and engine combination. Without it, the module will not function.
Where is the FPCM located on my vehicle?
On most trucks and large SUVs like the Silverado, Sierra, Tahoe, and Escalade, the module is mounted on the driver’s side frame rail, near the spare tire. On other vehicles like the Traverse or Acadia, it may be on a rear crossmember. It is typically exposed to the elements, which is a common reason for its failure due to corrosion.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is straightforward. After disconnecting the battery, you simply locate the old module, unplug the electrical connector, unbolt it from the frame, and then install the new one in its place. Since our module comes pre-programmed, no further steps are needed.
How do I provide my VIN after purchase?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship the part until we receive this information, as the programming is a critical part of your order.
Will this fix a P069E trouble code?
DTC P069E (Fuel Pump Control Module Commanded OFF) is one of the most common codes indicating a faulty FPCM. While you should always perform a complete diagnosis, this module is the most frequent cause and solution for this specific code.
