Restore Reliable Fuel Delivery to Your GM Vehicle
Is your 2008-2009 Express 1500 Van or other GM truck experiencing frustrating issues like stalling, hesitation, or a complete no-start condition? Before you condemn the fuel pump, the culprit is often its electronic controller. This Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM), is the vital component that regulates voltage to your fuel pump, ensuring precise fuel pressure for optimal engine performance. When it fails, it can leave you stranded and scratching your head.
Over my 20+ years in the shop, I’ve seen countless FPCMs fail, especially on trucks and vans where they are mounted to the frame rail. Constant exposure to road salt, water, and vibration takes a toll, leading to internal corrosion and electrical faults. The result is erratic fuel pressure, a check engine light, and a vehicle that’s simply not dependable.
Is Your GM Truck or Van Showing These Symptoms?
A failing FPCM can mimic a bad fuel pump, so proper diagnosis is key. Watch for these common indicators before replacing more expensive parts:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Severe engine hesitation or sputtering during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109 (Loss of Communication with Fuel Pump Control Module)
From the Diagnostic Bay: The ‘Bad’ Fuel Pump That Wasn’t
A customer brought in his ’08 Silverado, convinced his new fuel pump was defective. He’d replaced it himself after the truck left him stranded, but it still wouldn’t start consistently. He was frustrated and out a few hundred dollars. I hooked up my scan tool and immediately saw a U0109 code—no communication with the FPCM. We put the truck on the lift, and a quick inspection of the module on the driver’s side frame rail told the whole story. The housing was corroded and the connector pins were green with oxidation. We installed one of our pre-programmed modules, and the truck fired up instantly with perfect fuel pressure. This simple check saved him from another unnecessary repair and got his truck running reliably.
The Smart Solution: A VIN-Programmed 2008-2009 Express 1500 FPCM
The biggest hurdle with replacing an FPCM has always been the required dealership programming. A new module from the parts store is just a blank box; it won’t work until it’s flashed, costing you extra time and money for a tow and dealer labor. We eliminate that step entirely. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will program this module with the latest, most stable GM-certified software specific to your vehicle. It arrives at your door ready for a true plug-and-play installation.
A Straightforward Guide to FPCM Installation
Replacing the FPCM is a job most DIYers can handle with basic tools. While locations vary slightly by model, the process is generally the same.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and vans like the Express, Tahoe, and Silverado, you’ll find the FPCM mounted to the inside of the driver’s side frame rail, often near the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connectors. Use a small screwdriver to release the locking tabs if necessary. Then, unbolt the module from the frame.
- Install the New Module: Bolt the new, pre-programmed FPCM into the original location. Ensure the mounting surface is clean for a good ground connection.
- Reconnect and Secure: Firmly plug in the electrical connectors until they click. Give them a gentle tug to ensure they’re secure. Reconnect your battery terminal.
- Final Check: Turn the key to the ‘On’ position for a few seconds to allow the fuel system to prime, then start the engine. Your vehicle should now run smoothly.

Frequently Asked Questions
Why do you need my VIN?
Your VIN (Vehicle Identification Number) allows us to load the exact GM factory software for your vehicle’s specific configuration. This ensures perfect communication between the FPCM and other vehicle systems, guaranteeing a seamless, plug-and-play installation without a trip to the dealer.
Is this part difficult to install?
Not at all for most DIYers. It typically involves unbolting the old module from the frame rail, unplugging it, and installing the new one. Basic hand tools are all that’s required. Since our module is pre-programmed, no complex computer work is needed.
Where is the FPCM located on my 2009 Express Van?
On the 2008-2009 Express 1500 Van, the Fuel Pump Control Module is typically mounted on the left-hand (driver’s side) frame rail, towards the rear of the vehicle. Always confirm the location on your specific vehicle before starting.
What if my original part number isn’t 25967325?
This module is a direct replacement for a range of GM part numbers, including 13501024, 15213110, 20759945, and more. As long as your vehicle is on our compatibility list, this part will function correctly once programmed to your VIN.
Will this fix a P069E trouble code?
Yes, the DTC P069E (Fuel Pump Control Module Requested MIL Illumination) is one of the most common codes indicating a failed FPCM. Replacing a faulty module with our pre-programmed unit is the correct and effective repair for this code.
