Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If your 2007-2009 Silverado 1500, Sierra, Tahoe, or another compatible GM vehicle is experiencing frustrating fuel delivery problems, a faulty Fuel Pump Control Module (FPCM) is a very common culprit. This small but critical electronic component is responsible for precisely managing the voltage sent to your fuel pump. When it fails, it can leave you stranded with a vehicle that cranks but won’t start, stalls unexpectedly, or runs rough. Don’t waste time and money replacing a perfectly good fuel pump when the FPCM is the real issue.
The Critical Role of a Programmed Silverado Fuel Pump Module
Unlike older vehicles with simple fuel pump relays, modern GM trucks use a sophisticated variable-pressure fuel system controlled by the FPCM. This module receives commands from the Engine Control Module (ECM) and adjusts the fuel pump’s speed to deliver the exact amount of fuel the engine needs. This improves efficiency and performance, but it also means the FPCM must be perfectly calibrated to your specific vehicle. Our FPCM, part number 20759945, is the definitive solution. We take the guesswork out of the repair by pre-programming the module to your vehicle’s Vehicle Identification Number (VIN) before it ships. This ensures seamless communication with your truck’s computer systems, restoring original performance and reliability without a mandatory, expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2008 Sierra 1500 towed in with a classic ‘crank, no start’ condition. The owner had already replaced the in-tank fuel pump twice, assuming it was a bad part from the store. He was frustrated and out of options. After hooking up our scanner, we saw a specific diagnostic trouble code: P069E – Fuel Pump Control Module Commanded OFF. A quick check of the FPCM, located on the driver’s side frame rail, revealed heavy corrosion on the casing and connector. These modules live in a harsh environment, exposed to road salt, water, and debris. We installed one of our VIN-programmed modules, and the truck fired up on the first try. The customer could have saved hundreds of dollars and a lot of headaches by diagnosing the FPCM first.
Common Symptoms of a Failing FPCM
- ✔ Engine Cranks but Won’t Start: The most common symptom. The FPCM isn’t sending power to the fuel pump, so no fuel reaches the engine.
- ✔ Sudden Stalling: The vehicle may start and run fine for a few minutes, then stall without warning as the module overheats or fails intermittently.
- ✔ Engine Hesitation or Stumbling: Under acceleration, the module may fail to command enough fuel pressure, causing the engine to sputter or lose power.
- ✔ Check Engine Light: You will often see codes like P069E, P0230, or U0109, all pointing directly to a fault in the FPCM or its circuit.
- ✔ Reduced Engine Power Message: The vehicle’s computer may put the truck into a ‘limp mode’ to prevent damage when it detects a critical fuel system fault.
- ✔ No Fuel Pump ‘Prime’ Sound: You may no longer hear the familiar 2-second hum of the fuel pump when you first turn the key to the ‘ON’ position.
Guaranteed Fitment and Easy Installation
This module is a direct replacement for a wide range of GM trucks and SUVs from 2007 to 2009. It is compatible with multiple OEM part numbers, including 13501024, 15213110, 20850907, 25866052, and 25967325, among others. Installation is straightforward for a DIY mechanic with basic tools. The module is typically located on the driver’s side frame crossmember, near the spare tire. Simply disconnect the battery, unplug the old module’s electrical connectors, unbolt it from the frame, and install the new one in its place. Since we’ve already handled the programming, your vehicle will be ready to go once it’s installed.
By purchasing from us, you get a reliable part that is programmed with the latest GM software updates for your specific VIN, ensuring optimal performance and longevity. Restore your vehicle’s dependability and get back on the road with confidence.
Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. The main benefit of our service is that we program the module for you before we ship it. You must provide your vehicle’s 17-digit VIN during or after checkout so we can load the correct GM software for your specific vehicle.
Where is the FPCM located on my 2008 Silverado?
On most GM trucks and SUVs of this era, including the Silverado, Sierra, and Tahoe, the Fuel Pump Control Module is bolted to a frame crossmember on the driver’s side, typically above or near the spare tire.
What happens if I install a module that isn’t programmed?
An unprogrammed module will not work. The vehicle will not start, and it will set communication-related trouble codes. The FPCM must be calibrated to the vehicle’s VIN to communicate with the Engine Control Module (ECM) and other onboard systems.
Is this a genuine GM part?
This is a high-quality replacement part built to meet or exceed original equipment specifications. We use official GM-licensed software to program it, ensuring it functions identically to a part you would get from a dealership.
Could my problem just be the fuel pump?
While a fuel pump can fail, the FPCM is a very common point of failure on these vehicles due to its exposed location. If you are experiencing the symptoms listed, especially with FPCM-related trouble codes, the module is the most likely cause. Testing fuel pressure can help confirm a lack of fuel delivery commanded by the module.
How do I provide my VIN?
After you complete your purchase, please send us a message with your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is a required step.
