Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
A sudden loss of power, intermittent stalling, or a vehicle that cranks but won’t start can be incredibly frustrating, especially when you rely on your vehicle for work or family. These are classic signs of a failing Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This critical component regulates the voltage to your fuel pump, and when it fails, it starves your engine of the fuel it needs to run properly. Don’t let a small electronic module leave you stranded. This is the direct, reliable solution to get you back on the road with confidence.
Common Failure Symptoms & Your Direct-Fit Solution
If you’re experiencing any of the following issues, a faulty FPCM is the most likely culprit. This module is designed to permanently resolve these problems:
- Engine cranks but will not start
- Vehicle stalls intermittently, especially while driving
- Hesitation or stumbling under acceleration
- Reduced engine power and poor performance
- Check Engine Light with Diagnostic Trouble Codes (DTCs) such as P069E, P0230, or P0627
Our solution is simple and effective. We provide a genuine GM Programmed 20964304 Fuel Pump Control Module that is professionally flashed with the latest software update specifically for your vehicle’s VIN. This means it arrives at your door ready to install, with no need for an expensive trip to the dealership for programming.

An Expert’s Note on GM FPCM Failures
As a technician, I’ve seen countless GM trucks and SUVs sidelined by this exact issue. The original modules are often susceptible to failure from heat and vibration, especially on vehicles where they are mounted to the frame rail. The real headache for most owners isn’t the part replacement itself—it’s the programming. Without the correct software, the vehicle won’t recognize the new module. By supplying a Programmed 20964304 Fuel Pump Control Module, we bridge that gap, empowering both professional shops and capable DIYers to complete the job correctly and efficiently, saving critical time and money.
Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s Vehicle Identification Number (VIN) is essential for us to load the correct GM software and calibration files onto the module. This ensures the FPCM communicates perfectly with your vehicle’s computer (ECM) and other systems, making the installation truly plug-and-play.
Is this part difficult to install?
For most listed vehicles, the module is located on the driver’s side frame rail or in the rear of the vehicle. Installation typically involves disconnecting the battery, unplugging the electrical connectors, and removing a few bolts. It is a straightforward job for someone with basic mechanical skills. Since our module is a Programmed 20964304 Fuel Pump Control Module, no post-installation programming is needed.
Will this fix a P069E trouble code?
Yes, DTC P069E (Fuel Pump Control Module Commanded OFF) is one of the most common codes indicating a failed FPCM. Replacing the module with this pre-programmed unit is the standard and effective repair for this code, assuming the related wiring is intact.
How can I be sure my original module has failed?
Besides the common symptoms like stalling or no-start, a mechanic can test for power at the fuel pump and check for communication with the FPCM using a capable scan tool. Often, a complete lack of fuel pressure when the key is turned on points directly to the FPCM or the fuel pump itself. The FPCM is a more frequent and less expensive failure point to address first.
What happens if I install it without providing a VIN for programming?
An unprogrammed module will not work. The vehicle’s security system will not recognize it, and it will not be able to operate the fuel pump. It is absolutely critical that you provide your VIN so we can program it before shipping.
