2000 Toyota Echo Fuel Pump Relay Location: A Complete Guide for DIY Owners

If your 2000 Toyota Echo cranks but won’t start, or if the engine starts and then dies shortly after, the fuel pump relay is one of the first components you should check. The fuel pump relay on a 2000 Toyota Echo is located inside the interior fuse box, which is positioned under the dashboard on the driver’s side, near the left kick panel. The relay is typically labeled as “Fuel Pump” or “F/P” on the fuse box cover diagram. This guide will walk you through everything you need to know about locating, testing, and replacing the fuel pump relay on your 2000 Toyota Echo, along with practical troubleshooting tips.

Understanding the Fuel Pump Relay in Your 2000 Toyota Echo

The fuel pump relay is an electrical switch that controls power to the fuel pump. When you turn the ignition key to the “ON” position, the relay activates and sends current to the fuel pump, which pressurizes the fuel system so the engine can start. If the relay fails, the fuel pump won’t receive power, and the engine won’t run even if the pump itself is in good condition.

The 2000 Toyota Echo, which is part of the first generation XP10 series (also sold as the Toyota Yaris in other markets), uses a standard relay design that is common across many Toyota models from that era . The relay is located in the interior fuse box, not under the hood.

Exact Location of the Fuel Pump Relay

Conclusion first: The fuel pump relay on a 2000 Toyota Echo is located in the interior fuse box, which is mounted under the dashboard on the driver’s side, just above the left footwell area. You need to open the driver’s side door and look at the plastic panel on the left side of the dashboard. The fuse box cover is a rectangular panel that can be pulled off by hand or with a flathead screwdriver.

Once you remove the cover, check the diagram printed on the inside of the fuse box cover. The fuel pump relay is usually labeled as “Fuel Pump,” “F/P,” or “Fuel Pump Relay” . If the diagram is missing or faded, consult the owner’s manual or look for a relay that matches the typical Toyota relay design: a small, square, black plastic box with four or five prongs.

The interior fuse box on the 2000 Toyota Echo also contains the main fuses for the engine control system, the ignition system, and other critical components. The fuel pump relay is typically located in the second row from the top, near the center of the fuse box . Some models may have a different layout, so it’s always a good idea to verify the labeling.

Step-by-Step Guide to Access the Fuel Pump Relay

  1. Park the vehicle safely. Make sure the engine is off, the key is removed from the ignition, and the parking brake is engaged.
  2. Open the driver’s side door. You will need enough room to access the lower dashboard area.
  3. Locate the fuse box panel. Look under the dashboard on the driver’s side, near the left knee bolster. The panel is a rectangular plastic cover about 4 inches by 6 inches.
  4. Remove the fuse box cover. Grip the top edge of the cover and pull firmly toward you. If it’s stuck, use a flathead screwdriver wrapped in a cloth to gently pry it open.
  5. Read the diagram on the cover. The inside of the cover has a printed diagram showing the location of each fuse and relay. Find the box labeled “Fuel Pump” or “F/P.”
  6. Identify the fuel pump relay. It will be a small, square relay that fits into a socket. It may be a different color from the surrounding fuses, often black or dark gray.
  7. Test or remove the relay. To remove the relay, grasp it firmly and pull straight upward. Use a relay puller tool or pliers if needed, but be careful not to damage the socket.

How to Test the Fuel Pump Relay

Before you buy a new relay, it’s worth testing the old one to confirm it’s the problem. Here’s a simple way to test it using a multimeter or a test light.

Method 1: Listen for the relay click
Turn the ignition key to the “ON” position (do not start the engine). Listen for a distinct clicking sound coming from the fuse box area. If you hear a click, the relay is likely working. If you hear nothing, the relay may be stuck open or faulty.

Method 2: Swap with a identical relay
The interior fuse box contains several relays of the same size and shape, such as the horn relay, the turn signal relay, or the main relay. Identify a relay that is identical to the fuel pump relay, remove it, and swap it with the fuel pump relay. If the engine starts after swapping, the original relay is defective.

Method 3: Use a multimeter
Remove the relay and set your multimeter to measure resistance (ohms). Check the resistance between the coil terminals (usually pins 85 and 86 on a standard 4-pin relay). A good relay should show a resistance reading between 50 and 200 ohms. If the reading is infinite or zero, the relay is faulty .

Common Symptoms of a Bad Fuel Pump Relay

If the fuel pump relay is failing or has failed, you may experience one or more of the following symptoms:

  • Engine cranks but won’t start. This is the most common symptom. The starter motor turns the engine over, but the fuel pump doesn’t run, so no fuel reaches the injectors.
  • Engine starts and then dies. The relay may work briefly when the key is first turned, but then loses contact, causing the pump to stop.
  • No fuel pump noise when key is turned. Normally, you should hear a brief whirring sound from the fuel pump for about 2-3 seconds when you turn the ignition to the “ON” position. If you don’t hear this sound, the relay or the pump itself may be the issue.
  • Intermittent starting problems. The car may start fine some days but refuse to start on other days, especially when the relay is cold or hot.
  • Check Engine Light comes on. A faulty relay can trigger a diagnostic trouble code (DTC) related to the fuel pump circuit, such as P0230 (Fuel Pump Primary Circuit Malfunction).

Other Possible Causes of No-Start

A faulty fuel pump relay is not the only reason your 2000 Toyota Echo won’t start. Before you replace the relay, consider these other possibilities:

  • Blown fuel pump fuse. The interior fuse box also contains a fuse for the fuel pump. Check the fuse labeled “Fuel Pump” or “F/P” first. If the fuse is blown, replace it with a fuse of the same amperage rating .
  • Bad fuel pump. The pump itself may have failed, especially if it has high mileage (over 100,000 miles). A failing fuel pump often makes a loud humming noise before it dies completely.
  • Faulty fuel pump relay connector. The plastic socket that holds the relay can become corroded or loose over time, preventing good electrical contact .
  • Engine control module (ECM) issues. In rare cases, the ECM may not be sending the signal to activate the relay. This is more common on older vehicles with high mileage .

Step-by-Step Replacement Guide for the Fuel Pump Relay

Replacing the fuel pump relay on a 2000 Toyota Echo is a simple job that takes about 5 minutes. Here’s how to do it:

  1. Purchase a replacement relay. You can buy a new fuel pump relay from an auto parts store like AutoZone, O’Reilly Auto Parts, or online. Make sure the relay matches the original in terms of pin configuration and amperage rating. The standard Toyota relay is a 4-pin or 5-pin design.
  2. Disconnect the battery. To be safe, disconnect the negative terminal of the battery before working on electrical components.
  3. Access the interior fuse box. Follow the steps above to locate and open the fuse box cover.
  4. Remove the old relay. Grasp the relay firmly and pull it straight up out of the socket. If it’s stuck, use a small pair of pliers to gently wiggle it loose.
  5. Install the new relay. Align the prongs of the new relay with the socket and push it down firmly until it clicks into place.
  6. Reconnect the battery. Reattach the negative battery terminal.
  7. Test the new relay. Turn the ignition key to the “ON” position and listen for the fuel pump to prime. Then start the engine.

Troubleshooting Tips for the Fuel Pump Relay

If you’ve replaced the relay and the car still won’t start, don’t give up. Here are a few more things to check:

  • Check the fuel pump fuse again. Sometimes a new fuse can blow immediately if there is a short circuit in the fuel pump wiring.
  • Inspect the relay socket. Look for signs of corrosion, melting, or loose pins. Clean the socket with electrical contact cleaner if necessary.
  • Test the fuel pump itself. You can use a test light to check if the pump is getting power at the fuel tank connector. If the pump has power but doesn’t run, the pump is bad.
  • Check the fuel pump ground. The pump ground wire is usually attached to the chassis near the fuel tank. Make sure it’s clean and tight.
  • Listen for the fuel pump prime. Turn the key to “ON” and listen for a 2-second whirring sound from the rear of the car. If you don’t hear it, the pump isn’t priming.
