If your 2008-2009 Express 1500 Van is suddenly stalling, hesitating, or refusing to start, the culprit is often a component many overlook: the Fuel Pump Control Module (FPCM). As a technician with over two decades of experience, I’ve seen countless GM trucks and vans sidelined by this exact issue. The FPCM, also known as a Fuel System Control Module (FSCM), is the brain behind your fuel pump, and when it fails, it starves your engine of the fuel it needs to run reliably.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and dealership hassle out of the equation. Before this module ships, we will program it with the latest GM-approved software, flashed specifically to your vehicle’s VIN. This ensures flawless communication and performance from the moment you plug it in, restoring your vehicle’s factory-spec fuel delivery and reliability.
A Technician’s Notebook
I remember a 2008 Tahoe that came into my bay with a frustratingly intermittent no-start condition. The owner had already replaced the fuel pump, but the problem persisted. On a warm day, it would crank but never fire. After hooking up my scan tool, I monitored the desired vs. actual fuel pressure. The command was there, but the pump wasn’t responding. A quick voltage check at the FPCM connector confirmed my suspicion. The module, mounted on the frame rail and exposed to the elements, was failing when it got hot. We installed a pre-programmed FPCM, and the Tahoe has been running without a hiccup ever since. It’s a classic failure pattern for these vehicles.
Is Your GM Truck or Van Showing These Symptoms?
- ✔ Engine cranks but fails to start, especially when warm.
- ✔ Sudden engine stalling while driving, sometimes with no warning.
- ✔ Hesitation or stumbling under acceleration.
- ✔ Reduced engine power and poor performance.
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109 (Lost Communication With Fuel Pump Control Module).
- ✔ A whining noise from the fuel pump, as it may run at full speed constantly if the module fails.
Plug-and-Play Installation: Get Back on the Road Fast
Installing your new FPCM is a straightforward job for a DIYer or professional mechanic. Since we program it for you, no special scan tools are needed for setup.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and vans like the Express, the FPCM is mounted to the driver’s side frame rail, near the spare tire. On other models, it may be in the rear near a crossmember.
- Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle with the locking tabs, as they can become brittle. Then, remove the bolts or nuts securing the module to the frame.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Ensure it is securely mounted.
- Reconnect: Plug the electrical connectors firmly into the new module. You should hear a click as they lock in place.
- Final Step: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds before starting to allow the system to prime. Start the engine and check for proper operation.

Frequently Asked Questions
Do I really need to provide my VIN?
Yes, absolutely. The VIN is required for us to program the module with the correct GM software for your vehicle’s specific configuration. Without it, the module will not function correctly.
Is this part difficult to install?
For most DIYers with basic tools, this is a straightforward installation. The module is typically mounted on the frame and easy to access. Since it comes pre-programmed, no computer or special tool is needed for setup.
What if this doesn’t fix my problem?
While the FPCM is a very common failure point for these symptoms, we always recommend proper diagnosis. Other potential causes could be a faulty fuel pump, a clogged filter, or wiring issues. This module will resolve any issues directly caused by a failed FPCM.
Is this an OEM part?
This is a high-quality, tested replacement part that meets or exceeds original equipment specifications. We program it using official GM software updates for guaranteed compatibility and performance.
How do I send you my VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship your order until we receive and process this information.
