Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
There’s nothing more frustrating than a vehicle that won’t run reliably. If your 2008-2009 Chevrolet Express 1500, or another compatible GM vehicle, is experiencing issues like engine stalling, hesitation under acceleration, or a complete no-start condition, a faulty Fuel Pump Control Module (FPCM) is a very likely culprit. This critical component, also known as a Fuel System Control Module (FSCM), is responsible for precisely managing the voltage sent to your fuel pump. When it fails, it starves your engine of the fuel it needs to run, leaving you stranded. This replacement module, part number 25785013, is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a 2008 Silverado 1500 in the shop that was driving the owner crazy. It would stall randomly at stoplights and sometimes wouldn’t start at all after being parked. The owner had already replaced the in-tank fuel pump, but the problem persisted. After hooking up our diagnostic scanner, we noticed erratic voltage readings going to the fuel pump and a history code U0109 (Lost Communication With Fuel Pump Control Module). A quick inspection under the truck revealed the problem: the original FPCM, mounted directly to the frame rail on the driver’s side, was heavily corroded. Years of exposure to road salt and moisture had compromised the internal electronics. We installed a new, VIN-programmed module, and the truck fired up instantly and ran perfectly. It’s a classic failure on these vehicles, but thankfully, it’s a straightforward fix.
Symptoms of a Failing Fuel Pump Control Module
A failing FPCM can manifest in several ways, often mimicking a bad fuel pump. If you’re experiencing any of the following, it’s time to inspect your module. This is the exact part to get your vehicle running right again.
- ✔ Engine cranks but will not start
- ✔ Vehicle starts but stalls shortly after
- ✔ Intermittent stalling, especially when coming to a stop or under load
- ✔ Noticeable hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor performance
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, P0627, or U0109
- ✔ Inconsistent or no priming sound from the fuel pump when the key is turned
The Importance of a VIN-Programmed GM Fuel Control Module
Unlike simple relays of the past, the FPCM is a smart device that communicates with your vehicle’s primary computer (ECM/PCM). It must be programmed with your vehicle’s specific Vehicle Identification Number (VIN) to function correctly. A non-programmed module from a junkyard or a generic part will not work, leading to continued frustration and wasted money. We take the guesswork out of the repair. Simply provide us with your VIN during checkout, and our technicians will flash this module with the latest GM-certified software for your exact vehicle. It arrives at your door ready for a true plug-and-play installation, saving you a costly trip to the dealership for programming.
Direct-Fit Replacement and Wide Compatibility
This module is a direct replacement for original part number 25785013 and is also compatible with a wide range of other GM part numbers, including 13501024, 15213110, 20759945, 20850907, 25854536, 25866052, and 25967325. It is engineered to meet or exceed original equipment specifications for a perfect fit and reliable operation. While this listing is for the 2008-2009 Express 1500, this FPCM fits dozens of other GM models from the era, including:
- Cadillac Escalade, ESV, EXT
- Chevrolet Avalanche, Silverado 1500, Suburban, Tahoe, Colorado
- GMC Acadia, Sierra 1500, Yukon, Yukon XL, Canyon
- Buick Enclave, Saturn Outlook, Hummer H2 & H3
Installation is typically straightforward for those with basic mechanical skills. The module is most often found mounted to the driver’s side frame rail, near the spare tire. Simply disconnect the negative battery terminal, unplug the electrical connectors, unbolt the old module, and install the new one in its place. Reconnect everything, and you’re ready to go. Don’t let a faulty module keep you off the road. Order today and restore your vehicle’s fuel system to perfect working order.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. This Fuel Pump Control Module comes fully programmed to your vehicle’s specific VIN. We handle all the programming before it ships, so it’s ready for immediate installation right out of the box. Just provide your VIN when you order.
Where is this module located on my vehicle?
On most GM trucks and large SUVs like the Silverado, Sierra, Tahoe, and Express van, the FPCM is located on the driver’s side frame rail, often above the spare tire. On other models like the Acadia or Traverse, it may be on a rear crossmember. Always consult a repair manual for your specific vehicle if you are unsure.
Is this part compatible with part number 20759945?
Yes. This module is a direct, compatible replacement for a range of part numbers, including 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325.
What happens if I forget to provide my VIN?
Programming is essential for this part to function. We cannot ship the module until we receive your vehicle’s VIN. We will contact you after your purchase to remind you, but providing it during checkout will ensure the fastest possible processing and shipping.
How can I be sure the module is the problem and not the fuel pump?
While symptoms can overlap, a key indicator is the presence of specific communication-related trouble codes like U0109 or FPCM-specific codes like P069E. A technician can also test for voltage at the fuel pump connector; if there’s no or erratic voltage when the key is on, the FPCM is the most likely cause, assuming the wiring is intact.
