Chevy Silverado Fuel Pump Control Module Location: Where to Find It and How to Replace It

If you own a Chevy Silverado and your truck is showing signs of fuel system trouble—hard starting, stalling, or a check engine light with codes like P069E or P0087—the problem is often the fuel pump control module (FPCM). The fuel pump control module on a Chevy Silverado is located on the frame rail, near the spare tire, under the driver's side of the truck bed. For most models from 2007 through 2022, you will find it mounted to the frame rail behind the driver's side rear wheel, typically just above or near the spare tire. This is an external module, not inside the fuel tank, which makes it relatively easy to access and replace.

Understanding the Fuel Pump Control Module

The fuel pump control module is a small electronic box that regulates the voltage sent to the fuel pump. It receives a signal from your truck's engine control module (ECM) and adjusts the pump speed to deliver the exact fuel pressure needed for the current driving conditions . This variable-speed control improves fuel economy and reduces wear on the pump compared to older systems that ran the pump at full voltage all the time .

On the Chevy Silverado, this module is referred to by several names: fuel pump driver module, fuel pump power control module, or FPCM. Regardless of what you call it, it performs the same critical function. When it fails, the fuel pump either doesn't run at all or cannot deliver the pressure the engine needs, leading to performance problems or a no-start condition .

Where Is the Fuel Pump Control Module on a Chevy Silverado?

The exact location depends slightly on the model year, but the general placement is consistent. Here is a breakdown by generation:

2007-2014 Chevrolet Silverado (GMT900 Platform): The FPCM is mounted on the driver's side frame rail, near the rear of the vehicle. It is typically located just behind the driver's side rear door, close to the spare tire. You may need to lower the spare tire to get a clear view of the module . The module is held in place by bolts and has a wiring harness connector plugged into it.

2014-2022 Chevrolet Silverado (K2XX and T1XX Platforms): On these newer models, the module is in a similar location—on the driver's side frame rail, near the spare tire area. Some models may have it mounted slightly further forward, but it remains on the frame rail under the truck bed . GM also refers to this as the fuel pump driver control module on these models.

Important: Do not confuse the fuel pump control module with the fuel pump itself. The fuel pump is inside the fuel tank, which is located under the rear of the truck bed. The FPCM is an external module mounted on the outside of the frame .

How to Access the Fuel Pump Control Module

Accessing the FPCM on a Chevy Silverado is straightforward and typically requires no special tools. Here are the general steps:

  1. Safety first: Disconnect the negative battery cable before working on any electrical component. This prevents electrical shocks and protects the vehicle's computer systems .

  2. Locate the spare tire: The module is usually behind or above the spare tire. If necessary, lower the spare tire to gain better access. Most Silverado models have a crank mechanism under the rear seat or behind the license plate to lower the spare tire.

  3. Find the module: Look for a small black plastic or metal box mounted to the frame rail. It will have a wiring harness connected to it with a plastic clip or latch. The module is typically about 4 inches by 3 inches in size .

  4. Disconnect the wiring: Carefully press the release tab on the wiring harness connector and pull it straight off the module. Take note of the orientation of the connector—it only fits one way, but it helps to remember which direction it faces.

  5. Remove the mounting bolts: Use a socket or wrench to remove the bolts holding the module to the frame. There are usually two bolts. Once removed, the old module comes off by hand.

Signs Your Fuel Pump Control Module Is Failing

Knowing the symptoms of a bad FPCM can save you time and money. Here are the most common signs:

1. Engine cranks but will not start. This is the most frequent symptom. You turn the key, the engine spins over, but it never fires up. You may not hear the fuel pump prime when you turn the key to the "ON" position .

2. Stalling while driving. The truck runs fine for a while, then suddenly stalls as if it ran out of gas. It may restart after sitting for a few minutes, but the problem will return .

3. Check engine light with specific codes. The most common codes associated with a bad FPCM include P069E (Fuel Pump Control Module Requested MIL Illumination), P0087 (Fuel Rail Pressure Too Low), and U0109 (Lost Communication with Fuel Pump Control Module) .

4. Reduced engine power or limp mode. The truck may enter a "reduced power" mode, limiting speed and acceleration to protect the engine from running lean .

5. Hard starting or long cranking. The engine takes several seconds of cranking before it starts, especially on the first start of the day.

Replacement Considerations

When replacing the fuel pump control module, you have a few options:

OEM modules from GM are the most reliable but also the most expensive. They come with a factory warranty and are guaranteed to fit your vehicle .

Aftermarket modules from brands like ZOOKOTO cost less but vary in quality. Some aftermarket units work well, while others may fail shortly after installation .

Programming requirement: Many FPCMs require programming to your specific vehicle. Some modules come pre-programmed to your VIN, which saves you a trip to the dealer. If you buy a blank module, it will not work until it is programmed with the correct software for your truck's engine and configuration .

The replacement job itself is simple and can be done in about 30 minutes with basic hand tools. The labor time according to GM is 0.5 hours . No special skills are needed beyond being able to disconnect a battery and remove a couple of bolts.
