If your 2008-2009 GMC Savana 1500 is experiencing frustrating issues like cranking but not starting, stalling unexpectedly, or a persistent Check Engine Light, the culprit is often the Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). In my 20+ years of diagnostics, I’ve seen countless vehicle owners and even professional shops misdiagnose this part, needlessly replacing perfectly good fuel pumps. This module is the brain behind your fuel delivery, and when it fails, it starves the engine of the fuel it needs to run properly.
We solve this problem with a reliable, direct-fit solution. This FPCM is not just a part in a box; it’s a complete fix. We pre-program the module with the latest GM software updates specifically for your van using the VIN you provide. This means you can skip the expensive trip to the dealership for programming. It arrives at your door ready for a straightforward installation, restoring your vehicle’s performance and reliability.
From the Diagnostic Bay: The Fuel Pump That Wasn’t the Problem
A customer brought in his 2008 Silverado—which uses the same FPCM system as your Savana—with a frustrating story. He was on his third fuel pump in six months. The truck would run fine for a few weeks, then start to hesitate and eventually leave him stranded. Each time, his mechanic diagnosed a weak fuel pump. But after the third replacement, he came to my shop. I connected my scan tool and immediately saw DTC P069E (Fuel Pump Control Module Commanded OFF). The FPCM wasn’t providing consistent voltage, causing the pumps to work erratically and fail prematurely. We installed a new, properly programmed FPCM, and the truck has run flawlessly ever since. This isn’t just about fixing a no-start; it’s about protecting your entire fuel system.
Is Your Van Exhibiting These FPCM Failure Signs?
A failing 2008-2009 Savana 1500 FPCM can manifest in several ways. If you’re noticing any of the following, this module is the likely solution.
- ✔ Engine cranks but will not start.
- ✔ Extended cranking time before the engine fires up.
- ✔ Vehicle stalls while driving, especially under load.
- ✔ Rough idle or engine hesitation during acceleration.
- ✔ Check Engine Light is on with fuel system diagnostic trouble codes (DTCs) like P069E, P0230, or P0627.
- ✔ A noticeable loss of engine power and poor fuel economy.
A Straightforward Guide to Installation
Installing your new FPCM is a manageable job for a DIYer with basic tools. The key is our pre-programming service, which eliminates the most complex step. Always consult a service manual for your specific vehicle, but here is a general guide.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most Savana and Express vans, the FPCM is mounted to the driver’s side (LH) frame rail, near the spare tire. It’s a small black box with an electrical connector and is often exposed to the elements.
- Remove the Old Module: Unplug the electrical connector. Be gentle with the locking tab, as old plastic can be brittle. Then, remove the bolts or nuts holding the module to the frame.
- Install the New Module: Mount your new, pre-programmed FPCM in the same location. It’s a good idea to clean the mounting surface and apply a bit of dielectric grease to the connector pins to protect against future corrosion.
- Reconnect and Verify: Plug in the electrical connector until it clicks securely. Reconnect the negative battery terminal. Turn the key to the ‘On’ position for a few seconds before starting to allow the system to prime. Start your engine and confirm the fix.
Why a Programmed 2008-2009 Savana 1500 FPCM is the Smart Choice
Choosing this module isn’t just about replacing a broken part; it’s about making a smart repair. The module’s software is critical for managing fuel pressure based on engine load, and outdated software can cause performance issues. Our service ensures your new FPCM has the most current GM calibrations, providing optimal efficiency and engine health from the moment you install it. This is the definitive solution for a wide range of GM vehicles suffering from these common fuel system electronic failures.

Frequently Asked Questions
Do I need to do any programming after I receive this module?
No. This module arrives fully programmed to your vehicle’s VIN. It is a true plug-and-play solution, saving you a trip to the dealer and associated programming fees.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship the module without it.
Is this part the same as a fuel pump driver module?
Yes, the terms Fuel Pump Control Module (FPCM), Fuel System Control Module (FSCM), and Fuel Pump Driver Module (FPDM) are often used interchangeably for this component.
Could a bad FPCM damage my new fuel pump?
Absolutely. A failing FPCM can send erratic voltage to the fuel pump, causing it to overheat and fail prematurely. It’s always wise to check the FPCM when replacing a fuel pump on these vehicles.
Where is the FPCM located on my 2009 Savana 1500?
On the 2008-2009 Savana 1500, the FPCM is typically mounted on the outside of the left-hand (driver’s side) frame rail, often near the spare tire area.
