If your 2013 GMC Sierra 1500 is experiencing frustrating issues like engine stalling, hesitation during acceleration, or a dreaded no-start condition, a failing Fuel Pump Control Module (FPCM) is often the root cause. This critical component, also known as a Fuel System Control Module (FSCM), regulates the voltage sent to your fuel pump. When it fails, it starves your engine of the fuel it needs to run properly. This isn’t just an inconvenience; it’s a reliability issue that can leave you stranded. We offer a direct, effective solution: a genuine GM Fuel Pump Control Module, part number 20964304, delivered to your door fully programmed and ready for installation.
Case Study: A Tricky Diagnosis
I recently had a 2013 Sierra 1500 towed into my shop. The owner said it would crank all day but never fire up. He had already replaced the fuel pump himself, but the problem persisted. My first check with a scan tool revealed code U0109 – ‘Lost Communication With Fuel Pump Control Module.’ Instead of guessing, I went straight to the FPCM mounted on the driver-side frame rail. After years of exposure to road salt and moisture, the module’s housing was corroded, and the connector pins were green. This is a pattern I’ve seen on hundreds of these GM trucks. A new module fixed the issue instantly, but it required programming. This pre-programmed unit saves you that expensive final step at the dealership.
Is Your Truck Showing These Symptoms?
A failing FPCM can mimic other fuel system problems. Before you replace an expensive fuel pump, check if your vehicle is exhibiting these common signs of a bad 2013 Sierra 1500 Fuel Pump Control Module:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Severe engine hesitation or sputtering
- ✔ Reduced power and poor fuel economy
- ✔ Check Engine Light (CEL) with specific trouble codes
- ✔ Common Diagnostic Trouble Codes (DTCs): P069E, P0230, P2635, U0109
The Power of Pre-Programmed Convenience
Typically, replacing an FPCM requires two steps: the physical installation and a separate, costly programming session at a GM dealership. Without the correct software matched to your vehicle’s Vehicle Identification Number (VIN), a new module is just a paperweight. We eliminate that hassle. Simply provide us with your VIN during checkout, and our technicians will flash this module with the latest, most stable GM software for your exact vehicle. It arrives ready to install, turning a multi-day, expensive repair into a simple job you can do in your own driveway.
A Straightforward Guide to Installation
Installing your new 2013 Sierra 1500 Fuel Pump Control Module is a manageable task for a DIY enthusiast. It’s typically located on the driver’s side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FPCM on the exterior of the driver-side frame rail. It’s a small black box with an electrical connector.
- Disconnect and Remove: Carefully unplug the electrical harness. Then, remove the bolts or nuts (usually 2 or 3) holding the module to the frame.
- Install the New Module: Mount your new, pre-programmed FPCM in the same location and secure it with the original hardware.
- Reconnect: Plug the electrical connector firmly into the new module until it clicks. Reconnect your battery terminal.
- Final Check: Start the engine. It may take a slightly longer crank the first time to prime the fuel system. Your truck should now run smoothly.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN is required to load the correct GM-certified software onto the module. This ensures perfect communication with your truck’s other computers, like the ECM and BCM, for flawless operation right out of the box.
What happens if I install a module without programming?
An unprogrammed module will not work. Your vehicle will not receive the correct signals to operate the fuel pump, and it will fail to start. Our pre-programming service solves this completely.
Is this a difficult part to replace myself?
For most DIYers with basic hand tools, this is a very straightforward repair. The module is typically in an accessible location on the frame rail, requiring only the removal of a few bolts and one electrical connector.
Will this fix a P069E check engine code?
Yes, the DTC P069E (Fuel Pump Control Module Requested MIL Illumination) is one of the most common codes indicating a faulty FPCM. Replacing it with this programmed unit is the correct repair for that code.
Is this part compatible with part number 20964305?
Yes, this module, part number 20964304, is a fully compatible and interchangeable replacement for part number 20964305.
