If your 2008-2009 Chevy Express 1500 work van is suddenly stalling, hesitating, or refusing to start, you’re not just losing a vehicle—you’re losing a critical business tool. In my 20+ years in the garage, I’ve seen countless technicians and DIYers chase their tails, replacing perfectly good fuel pumps only to find the real culprit was a faulty Fuel Pump Control Module (FPCM). This module, often exposed to harsh road conditions under the vehicle, is a common failure point on many GM trucks and vans.
This isn’t just a replacement part; it’s a complete solution. We take the hassle and high cost of dealership programming out of the equation. Simply provide us with your vehicle’s VIN after purchase, and our technicians will flash this module with the latest, most stable GM software specific to your Express Van. It arrives at your door ready for a true plug-and-play installation, restoring proper fuel pressure regulation and getting your van back in service where it belongs.
A Technician’s Notebook: The Misleading Fuel Pump
I remember a 2008 Silverado that came into the bay on a tow truck. The owner had already replaced the in-tank fuel pump himself, but the truck still wouldn’t start. His scanner showed a code for low fuel rail pressure. He was convinced he got a bad pump. Instead of starting there, I hooked up my scan tool and commanded the fuel pump on—nothing. But I could hear the relay click. My next step was to check power and ground at the FPCM, located on the frame rail. I had good power going in, but the voltage coming out to the pump was erratic and low. The original FPCM had failed from corrosion. We installed a pre-programmed module, and the truck fired right up. He spent a weekend and hundreds on a pump he didn’t need, when the real fix was this module. Always check the FPCM first!
Is Your GM Truck or Van Showing These Symptoms?
A failing FPCM can mimic other fuel system problems. Before you spend a fortune on a new fuel pump, check if your vehicle is experiencing any of these common signs of a bad module:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Severe hesitation or stumbling during acceleration
- ✔ “Reduced Engine Power” message on the instrument cluster
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, P0606, or U0109
- ✔ A buzzing or whining noise from the fuel pump that is inconsistent
A Straightforward Guide to Installation
Replacing the 2008-2009 Express 1500 Fuel Pump Module is a job most DIYers with basic tools can handle. Since this module comes pre-programmed, no special scanners are needed.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most GM trucks and vans like the Express, the FPCM is mounted to the driver’s side frame rail, often near the spare tire. It’s a small black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly. 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 original location. Be sure to clean the mounting surface to ensure a good ground connection if applicable.
- Reconnect and Finalize: Securely plug the electrical connectors back into the new module. You should hear a distinct click. Reconnect the negative battery terminal.
- Cycle the Key: Turn the ignition key to the ‘On’ position (without starting the engine) for 10 seconds to allow the system to prime. Start the vehicle and check for proper operation.

Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN (Vehicle Identification Number) allows us to flash the module with the exact software calibration GM specifies for your vehicle’s unique configuration. This ensures perfect compatibility and performance, eliminating the need for a trip to the dealer.
Is this part difficult to install?
No, this is a straightforward replacement. It’s typically mounted on the frame rail and held by a few bolts. Since it comes pre-programmed, the installation is a simple plug-and-play process that requires only basic hand tools.
What is the most common cause of FPCM failure?
The most common cause is exposure to the elements. Being mounted under the vehicle, these modules are subjected to water, road salt, and dirt, which can lead to corrosion and internal electronic failure over time.
Will this fix a P069E check engine light code?
Yes, the DTC P069E (Fuel Pump Control Module Commanded Performance) is a very strong indicator that the FPCM has failed. Replacing it with this pre-programmed unit is the correct and most common repair for this code.
Is this a new or used part?
This is a high-quality, fully tested replacement part that has been loaded with new, vehicle-specific GM software. It is guaranteed to restore your vehicle’s fuel system to proper working order.
