2000 Subaru Forester Fuel Pump Relay Location: Quick Guide and Replacement Tips

If you own a 2000 Subaru Forester and your car is having trouble starting, stalling, or losing power, the fuel pump relay is often the first component to check. The fuel pump relay on a 2000 Subaru Forester is located inside the main fuse box under the dashboard, on the driver's side, near the steering column. This small but critical part controls power to the fuel pump, and when it fails, your engine won't get the fuel it needs. This guide walks you through exactly where to find it, how to test it, and what to do if it needs replacement.

Understanding the Fuel Pump Relay in a 2000 Subaru Forester

The fuel pump relay acts like a switch that sends electricity to the fuel pump when you turn the ignition key. On the 2000 Subaru Forester, this relay is part of the vehicle's electrical system and is designed to handle the current needed to run the fuel pump. When the relay fails, the fuel pump doesn't get power, and the engine either cranks without starting or dies while driving.

The relay itself is a small black or gray box with four or five prongs on the bottom. It clicks when it engages, and you can often hear that sound when someone turns the key to the "on" position. If you don't hear that click, the relay might be bad, or there could be a wiring issue.

Exact Location of the 2000 Subaru Forester Fuel Pump Relay

The 2000 Subaru Forester fuel pump relay is located in the main fuse box, which is under the dashboard on the driver's side. Here's how to find it step by step:

  1. Get into the driver's seat and look under the dashboard, just above the footwell area. You'll see a plastic cover that is about 6 inches wide and 4 inches tall. This cover is the fuse box door.

  2. Remove the plastic cover by pulling it toward you. It usually snaps off with a gentle tug. Some models have a small tab you need to press to release it.

  3. Look at the diagram on the inside of the cover or on the fuse box itself. The diagram shows the location of each relay and fuse. The fuel pump relay is typically labeled "FUEL PUMP" or "FUEL." It is often a larger relay, usually the third or fourth relay from the left in the top row.

  4. Identify the relay by its shape and size. It is a square or rectangular block with a plastic housing. The color is usually black or dark gray, and it has four or five metal prongs on the bottom.

  5. If the diagram is missing or hard to read, you can check the owner's manual. The 2000 Subaru Forester owner's manual has a clear diagram of the fuse box and relay locations. If you don't have the manual, you can find a free PDF version online on Subaru forums or the official Subaru website.

How to Test the 2000 Subaru Forester Fuel Pump Relay

Before you buy a new relay, it's smart to test the old one. Testing is simple and requires only a few tools. Here's what you need:

  • A multimeter (or a test light)
  • A small flathead screwdriver (to help remove the relay)
  • A friend to help turn the key (optional)

Step 1: Remove the relay. Gently pull the relay straight up out of the fuse box. Use a small screwdriver to pry it out if it's stuck. Be careful not to damage the plastic housing or the pins.

Step 2: Check for power at the relay socket. Set your multimeter to DC voltage (20V range). Place the black probe on a good ground point (like a metal bolt on the car body). Touch the red probe to each of the four or five pins in the socket while a friend turns the ignition key to the "on" position. You should see 12 volts on two of the pins. If you don't see any voltage, the problem might be a blown fuse or a wiring issue, not the relay itself.

Step 3: Test the relay itself. Connect the multimeter to the relay's coil terminals (usually pins 85 and 86). The resistance should be between 50 and 120 ohms. If it reads infinite (open circuit) or zero (short circuit), the relay is bad. You can also apply 12 volts to the coil terminals and listen for a click. If you hear a click, the relay is likely working.

Step 4: Check for continuity. With the relay energized (clicked), check continuity between the switch terminals (usually pins 87 and 30). You should see less than 1 ohm of resistance. If you see infinite resistance, the relay is bad.

Common Symptoms of a Bad Fuel Pump Relay in a 2000 Subaru Forester

A failing fuel pump relay can cause several symptoms. Here are the most common ones:

  1. Engine cranks but won't start. This is the most obvious sign. The starter motor turns the engine over, but the fuel pump doesn't run, so no fuel reaches the engine.

  2. Engine stalls while driving. The relay can fail intermittently, causing the fuel pump to lose power while the car is moving. This is dangerous because you lose power steering and brake assist.

  3. No fuel pump sound when turning the key. When you turn the ignition key to the "on" position (before starting), you should hear a faint whirring sound from the rear of the car for about 2 seconds. That's the fuel pump priming. If you don't hear this sound, the relay might be bad.

  4. Check Engine Light comes on. The 2000 Subaru Forester has a diagnostic system that can detect a fuel pump relay failure. You'll see the Check Engine Light, and a code like P0230 (fuel pump primary circuit malfunction) or P0231 (fuel pump secondary circuit low) will be stored.

  5. Engine runs rough or hesitates. If the relay is failing but not completely dead, the fuel pump might get intermittent power, causing the engine to run lean or hesitate during acceleration.

Tools Needed for Testing and Replacing the Fuel Pump Relay

You don't need many tools to work on the fuel pump relay. Here's a short list:

  • A multimeter (digital or analog, but digital is easier to read)
  • A test light (optional, but good for quick voltage checks)
  • A small flathead screwdriver (to pry the relay out)
  • A pair of needle-nose pliers (if the relay is stuck)
  • A replacement relay (if needed)

How to Replace the 2000 Subaru Forester Fuel Pump Relay

Replacing the fuel pump relay is one of the easiest repairs you can do on a 2000 Subaru Forester. It takes about 5 minutes and requires no special skills. Here's how:

  1. Make sure the ignition is off and the key is removed from the ignition switch. You don't want any power flowing while you work.

  2. Locate the relay as described above. Pull it straight out of the fuse box. If it's tight, use a small screwdriver to gently pry it up.

  3. Compare the new relay to the old one. Make sure the new relay has the same number of pins (usually 4 or 5) and the same pin layout. The part number on the relay should match. The 2000 Subaru Forester uses a standard relay, and you can find it at most auto parts stores.

  4. Push the new relay into the socket until it clicks into place. Make sure it's fully seated. You shouldn't see any gap between the relay and the socket.

  5. Test the new relay. Turn the ignition key to the "on" position and listen for the fuel pump priming sound. Start the engine. If it starts and runs smoothly, the repair is done.

  6. Replace the fuse box cover and close it securely.

Where to Buy a Replacement Fuel Pump Relay for a 2000 Subaru Forester

You can buy a replacement fuel pump relay at most auto parts stores like AutoZone, Advance Auto Parts, O'Reilly Auto Parts, or NAPA.

When to Call a Professional

While the fuel pump relay is easy to replace, some related problems are best left to a mechanic. If you test the relay and it's good, but the fuel pump still doesn't run, the issue could be:

  • A blown fuel pump fuse (check the fuse box under the dashboard)
  • A bad fuel pump (located inside the fuel tank)
  • A wiring problem between the relay and the pump
  • A faulty ignition switch or engine control module (ECM)

If you're not comfortable working with electrical systems, or if the problem persists after replacing the relay and checking the fuse, take your 2000 Subaru Forester to a trusted mechanic. They can perform a more detailed diagnosis using a scan tool and a wiring diagram.

Preventing Future Fuel Pump Relay Problems

The fuel pump relay on a 2000 Subaru Forester is a simple mechanical device, but it can fail over time. Here are a few tips to extend its life:

  • Keep the fuse box clean. Dust and moisture can cause corrosion on the relay pins. Use a dry cloth to clean the fuse box area every few months.
  • Check the fuse box for water leaks. If water gets into the fuse box, it can short out the relay. Look for signs of rust or water stains.
  • Replace the relay every 10 years as preventive maintenance. The relay is cheap, and replacing it before it fails can save you a tow truck bill.
  • Use a quality relay. Cheap relays can fail quickly. Stick with brands like KEMSO for reliability.
