Restore Your Truck’s Performance and Reliability
Is your 2013 Silverado 1500 experiencing frustrating issues like stalling, hesitation on acceleration, or a dreaded no-start condition? Before you consider replacing the entire in-tank fuel pump, the problem often lies with a faulty Fuel Pump Control Module (FPCM). As a technician with over two decades of experience, I’ve seen countless vehicle owners and even other shops misdiagnose these symptoms. This module is the brain of your fuel system, and when it fails, it can mimic a bad fuel pump, leading to wasted time and money. This replacement FPCM, part number 20964304, is the direct, reliable solution you need.
The biggest challenge with replacing an FPCM has always been the mandatory, and often expensive, trip to the dealership for programming. We eliminate that step completely. When you order from us, we flash the module with the latest official GM software, specifically matched to your truck’s Vehicle Identification Number (VIN). It arrives at your door ready for a simple, plug-and-play installation, getting you back on the road quickly and affordably.
From the Diagnostic Bay: The Stalling Silverado
A customer brought in his 2013 Silverado 1500 that would randomly stall at stoplights and sometimes refuse to start after being parked for an hour. He was convinced he needed a new fuel pump. I hooked up my diagnostic scanner and saw no fuel pressure codes, but I did find a U0109 code—Lost Communication with Fuel Pump Control Module. Instead of jumping to the expensive in-tank pump job, I inspected the FPCM on the frame rail. It showed classic signs of corrosion from road salt and moisture. We installed a new, pre-programmed module, and the truck ran perfectly. This simple part saved the customer over $800 on an unnecessary fuel pump replacement.
Is Your Silverado Showing These Signs?
A failing FPCM can cause a range of confusing symptoms. Check if your truck is experiencing any of the following:
- ✔ Engine cranks but won’t start
- ✔ Stalling, especially when coming to a stop or at idle
- ✔ Severe engine hesitation or sputtering under load
- ✔ Loss of power during acceleration
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
- ✔ A whining noise from the fuel pump that is inconsistent
A Straightforward Guide to Installation
Installing your new 2013 Silverado 1500 Fuel Pump Control Module is a job most DIYers can handle with basic tools. For the Silverado, it’s typically located on the driver-side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FPCM mounted to the frame rail. It’s a small black box with electrical connectors. You may need to lower the spare tire for better access.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note their orientation. Then, unbolt the module from the frame. These bolts can be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed FPCM into the same location. Ensure it is securely fastened.
- Reconnect Everything: Plug the electrical connectors firmly into the new module. Reconnect the negative battery terminal.
- Final Check: Turn the key to the ‘On’ position for a few seconds to allow the system to prime, then start the engine. Your fuel delivery issues should be resolved.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. We handle all the programming for you before we ship the part. Just provide your vehicle’s VIN during checkout, and it will arrive ready to install. This saves you time and money.
Where is the FPCM located on my 2013 Silverado?
On the 2013 Silverado 1500, the Fuel Pump Control Module is typically mounted on the driver’s side (LH) frame rail, often above or near the spare tire.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive the VIN to perform the vehicle-specific programming.
Is this the same as a fuel pump relay?
No. A relay is a simple on/off switch. The FPCM is a sophisticated computer that precisely controls the voltage sent to the fuel pump, managing fuel pressure for optimal efficiency and performance.
What happens if I install it without programming?
An unprogrammed module will not work correctly. It will likely result in a no-start condition and set communication error codes because it cannot communicate with your vehicle’s other computers. Our pre-programming service ensures it works perfectly out of the box.
