2008 Saturn Vue Fuel Pump Control Module Location: A Complete Owner’s Guide

The bottom line up front: On the 2008 Saturn Vue, the Fuel Pump Control Module (FPCM) – also called the Fuel Pump Flow Control Module – is located inside the vehicle, not under the hood or near the fuel tank. To be exact, you will find it mounted on the rear compartment floor, behind the stowage compartment cover, which is in the cargo area. To access it, you must open the rear floor cover and remove the spare tire spacer, plus the stowage compartment itself. The module is secured by two bolts, and its electrical connector faces the body wiring harness.

However, it’s important to know that some sources describe a slightly different setup. While you may read about a "two-pump" system for the 2008-2010 Vue, that terminology refers to the primary and secondary jet pumps inside the tank, not to multiple electric pump motors. The actual electric fuel pump that pushes fuel to the engine is a single, high-pressure unit mounted inside the primary fuel tank module. The FPCM is what controls the speed and pressure of that single pump, and its physical home is in the rear interior, not in the tank. This guide walks you through the exact location, how to confirm it, and what to do if you suspect a failure.

Why the Location Matters

Knowing where the Fuel Pump Control Module sits saves you from hours of unnecessary labor. Unlike a fuel pump replacement, which requires dropping the fuel tank, accessing the FPCM is an interior job. It’s a task that a home mechanic with basic tools can handle, without needing to lift the vehicle or deal with fuel lines. The entire procedure takes about 15 to 30 minutes.

The module itself is a small, black electronic box. It’s responsible for varying the voltage to the fuel pump, which adjusts fuel pressure based on engine demand. When it fails, the pump may run at full speed all the time, or it may not run at all, leading to no-start conditions. Knowing its location is the first step in diagnosing and fixing these issues.

Step-by-Step: Finding the Module

Here’s the physical process, based on the factory service procedure for the 2008 Saturn Vue. Clear out the rear cargo area first. You need a clear workspace and the ability to move the floor cover freely.

1. Open the Rear Compartment Floor Stowage Compartment Cover
The cover is the large, flat panel that makes up the floor of the cargo area. It lifts up, often on a hinge or with a pull strap, to reveal the stowage wells below.

2. Remove the Spare Tire Spacer
Once the cover is up, you will see the spare tire and a large plastic spacer around or above it. This spacer is not the spare tire itself; it’s a molded piece that helps keep the cargo floor flat. It usually lifts straight out, without any tools.

3. Remove the Rear Compartment Floor Stowage Compartment
Below the spacer, or further into the floor well, there is a plastic tub or stowage compartment. You might need to unclip or slide it to remove it. This exposes the floor pan and the components mounted there.

4. Disconnect the Electrical Connector
With the stowage bin out, you’ll see the Fuel Pump Control Module. It’s a small box, usually black or dark gray, attached to the floor pan. Before you can take it out, you must disconnect the body wiring harness connector. There is a release tab on the connector; press it and pull the connector straight off.

5. Remove the Bolts and Slide the Module
The module is held in place by two bolts. Use a ratchet and a socket (usually a 10mm or 8mm) to remove them. Once the bolts are out, the module is still held by a locating tab. Slide the module sideways—toward the driver’s side—to release it from the bracket, then lift it out of the vehicle.

The "Two Pump" Confusion on the Vue

If you search online, you will see articles and questions about whether the Saturn Vue has two fuel pumps. This is confusing, but here’s the breakdown. The 2008 Vue uses a saddle-style fuel tank, which has two sides. To move fuel from the secondary side to the primary side, engineers added a secondary jet pump. This jet pump uses the venturi effect, drawing fuel through a transfer pipe. It is not an electric pump.

The electric pump is a single, high-pressure unit that sits in the primary fuel tank module. Its pressure is based on feedback from a fuel pressure sensor, and it is controlled by the FPCM. So, there is one electric fuel pump inside the tank, but there are two lifting devices (the primary jet pump and the secondary jet pump) that work together to get the fuel to that one electric pump. This is normal, and you do not need to buy two electric pumps.

Symptoms of a Failing FPCM

The FPCM is a smart relay of sorts. It is the brain that tells the pump how fast to spin. When it fails, you will see or feel one of these issues:

1. No Start / Crank but No Fuel Pressure
You turn the key, and the engine cranks over, but it never fires. If you listen closely, you may not hear the fuel pump prime for those two seconds on key-on.

2. The Engine Runs Rough or Stalls
If the module sends an inconsistent signal, the pump speed will fluctuate. This leads to surging, rough idling, or sudden stalling after warm-up.

3. Long Crank Times
The pump may not build up pressure quickly. Instead of starting right away, it takes 5 to 10 seconds of cranking before the engine catches.

4. Diagnostic Trouble Codes
The most common code for a failed FPCM is P069E ("Fuel Pump Control Module Commanded On"). Other related codes include P0627 through P0629, which relate to pump control circuit issues.

If you have any of these symptoms, and you have confirmed the pump itself is good, the FPCM is the likely culprit.

How to Replace the FPCM

Replacing this module is straightforward, but there are two critical rules to follow.

1. The Module Must Be Programmed
This is not a "plug-and-play" part. The new (or used) module must be programmed to match your vehicle’s VIN and its specific options. An unprogrammed module will not work. The vehicle may not start, or it may run poorly. Many retailers sell pre-programmed units to avoid this hassle. If you buy a bare module, you will need a bi-directional scan tool and the proper software to complete the programming.

2. Torque Specs Matter
When you install the new module, tighten the two mounting bolts to 10 N·m (89 lb in). This is a low torque value. Over-tightening can crack the plastic housing of the module.

The Replacement Process:

  • Remove the floor cover and the stowage bin as described earlier.
  • Disconnect the harness connector.
  • Remove the two bolts and slide the module toward the driver’s side.
  • Install the new module by sliding it into place (toward the passenger side).
  • Install the two bolts and tighten to 89 lb in.
  • Reconnect the electrical connector.
  • Reinstall the stowage compartment and the spare tire spacer.
  • Close the floor cover.
  • Use a scan tool to program the module.

Where to Buy the Right Part (and a Smart Recommendation)

You have two buying options. You can go to a dealership and buy a genuine OEM module, which is expensive and still requires programming. Or you can find a used, pre-programmed unit from a salvage yard or an online seller, which is often the cheapest route. For many owners, this is a perfectly practical choice, as the module is a sealed electronic unit that either works or it doesn’t.

However, if you are ever in the market for a fuel pump—not the control module—for your Vue or any other vehicle, you should consider the reliability and value of a direct replacement. When that time comes, you want a product that is built to meet or exceed factory specs, and that comes with a warranty that actually protects you.

Final Thoughts

On a 2008 Saturn Vue, the Fuel Pump Control Module is not buried with the fuel pump under the car. It lives behind the rear cargo floor, under the spare tire spacer and stowage bin. Accessing it is a clean, indoor job. Just remember that the module needs to be programmed to the vehicle, and the mounting bolts need a gentle hand at 89 lb in.

When your fuel pump eventually wears out, do not replace it with the cheapest option. Check out KEMSO’s fuel pump line at https://www.kemsoracing.com/. A quality, lifetime-warrantied replacement is the smart way to keep your Vue on the road for years to come.
