2000 Toyota Camry Fuel Pump Relay Location: The Complete Guide to Finding, Testing, and Replacing It

The bottom line: The fuel pump relay on a 2000 Toyota Camry is located in the under-hood fuse and relay box, typically near the battery or the air filter housing. If your Camry cranks but won’t start, the relay is one of the first parts you should check before replacing the fuel pump itself.

This guide walks you through everything you need to know about the fuel pump relay on a 2000 Toyota Camry. You will learn exactly where to find it, how to test it, how to replace it, and what to do if the relay is not the problem. This information is practical for any DIY owner who wants to save time and money on diagnostics.

Why the Fuel Pump Relay Matters

The fuel pump relay is a small electronic switch that controls power to the fuel pump. When you turn the ignition key to the ON position, the relay closes and sends battery voltage to the fuel pump. The pump then pressurizes the fuel system so the engine can start. On a 2000 Toyota Camry, the fuel pump only runs for about two seconds when you first turn the key, unless the engine is cranking or running. If the relay fails, the pump never gets power, and the engine will crank but not fire.

A bad relay can mimic a dead fuel pump. Many owners replace the pump first, only to find out the real problem was a $10 relay. Always test the relay before you drop the fuel tank.

Where Is the Fuel Pump Relay on a 2000 Toyota Camry?

The 2000 Toyota Camry fuel pump relay is located in the engine compartment fuse box. This box is on the driver’s side, near the battery and the air filter housing. The relay is part of the EFI (Electronic Fuel Injection) system. In some Toyota models, this relay is specifically called the "Circuit Opening Relay."

Here is how to find it:

  1. Open the hood and locate the fuse box on the driver’s side. It is a black plastic box with a removable lid, usually positioned near the battery.
  2. Remove the fuse box lid. On the underside of the lid, there is a diagram that labels each relay and fuse. Look for a label that says "EFI," "Fuel Pump," or "Circuit Opening Relay."
  3. Identify the relay. The fuel pump relay is typically a cube-shaped component with four or five pins. It may be black, blue, or gray, depending on the manufacturer.
  4. If the diagram is unclear, consult your owner’s manual. The manual has a detailed layout of the engine compartment fuse box.

In some 2000 Camry models, the fuel pump relay is located behind the glove box on the passenger side. You have to remove the glove box to access a pack of three relays. The fuel pump relay is the middle one. However, the engine compartment location is more common for this year.

Symptoms of a Bad Fuel Pump Relay

A failing fuel pump relay usually shows clear symptoms. Here are the most common ones for a 2000 Toyota Camry:

  • Engine cranks but does not start. This is the number one symptom. You turn the key, the starter turns the engine over, but the engine never fires. The fuel pump is not getting power because the relay is stuck open.
  • Engine starts and then dies. The relay may work intermittently. It supplies power for a second, then fails. The engine starts but stalls immediately.
  • No noise from the fuel pump. When you turn the ignition to ON (without cranking), you should hear a faint buzzing or whining sound from the rear of the car for about two seconds. If you hear nothing, the relay or the pump is not receiving power.
  • Engine stalls while driving. If the relay fails while you are on the road, the pump loses power, and the engine shuts off. This is dangerous and indicates a complete relay failure.

Note that these symptoms can also be caused by a bad fuel pump, a blown fuse, or a faulty inertia switch. Testing the relay is the fastest way to narrow down the problem.

How to Test the Fuel Pump Relay

Testing the relay is straightforward. You do not need expensive tools. A multimeter or a test light is enough. Follow these steps:

Step 1: Locate the Relay

Find the fuel pump relay in the under-hood fuse box, as described above.

Step 2: Perform a Swap Test

This is the easiest method. Find another relay in the same fuse box that looks identical. The horn relay, the headlight relay, or the A/C relay are often the same size and pin configuration. Swap the suspect relay with a known good one. If the engine starts after the swap, the original relay is bad.

Step 3: Test with a Multimeter

If you want to be precise, use a multimeter:

  1. Remove the relay from the fuse box.
  2. Set the multimeter to measure resistance (ohms).
  3. Check the coil side. On a standard 4-pin relay, there are two pins for the coil (usually pins 85 and 86). Measure resistance between these two pins. A good coil typically shows a reading between 50 and 200 ohms. If you see infinite resistance (open circuit), the relay coil is burned out.
  4. Check the switch side. The other two pins (usually 30 and 87) should show infinite resistance when the relay is not energized. This is the normally open position.
  5. Apply 12V power to the coil pins. You can use a 12V battery or a power supply. Connect the positive lead to pin 85 and the negative lead to pin 86. When power is applied, you should hear a distinct click. Now measure resistance between pins 30 and 87. It should be very low, near zero ohms. This means the switch has closed. If the relay does not click or the resistance does not change, the relay is defective.

Step 4: Check for Power at the Relay Socket

With the relay removed, turn the ignition to ON. Use a test light or multimeter to check for voltage at the socket terminals. One terminal should have constant 12V battery power. Another terminal should have 12V only when the ignition is ON. If you do not see power at these terminals, the problem is not the relay. It could be a blown fuse, a bad ignition switch, or a wiring issue.

What to Do If the Relay Is Good

If the fuel pump relay tests fine but the engine still does not start, move on to these other components:

Check the Fuel Pump Fuse

The 2000 Toyota Camry has one or more fuses that protect the fuel pump circuit. Look in the engine compartment fuse box for the "EFI" or "IGN" fuse. Remove the fuse and inspect the metal strip inside. If the strip is broken, replace the fuse with one of the same amperage. If the new fuse blows immediately, there is a short circuit in the wiring.

Check the Circuit Opening Relay (If Applicable)

Some 2000 Camry models use a separate "Circuit Opening Relay" that controls the fuel pump in conjunction with the main EFI relay. This relay is usually located in the same fuse box. Test it the same way you tested the main relay.

Check the Fuel Pump Itself

If the relay and fuses are good, the fuel pump may be dead. On a 2000 Toyota Camry, the fuel pump is located inside the fuel tank. To access it, you must remove the rear seat cushion. Under the cushion, there is an access panel on the floor. Remove the panel to reveal the fuel pump module. You can test the pump by applying 12V directly to its terminals. If the pump does not run, it needs replacement.

Check the Inertia Switch (Fuel Cutoff Switch)

Some Toyota models have an inertia switch that cuts power to the fuel pump in a collision. If the switch is tripped, the pump will not run. The switch is usually located in the trunk or under the dashboard. Consult your owner’s manual for the exact location.

How to Replace the Fuel Pump Relay

Replacing the relay is simple and takes less than five minutes. Here is what you do:

  1. Turn off the engine and remove the key from the ignition.
  2. Locate the relay in the engine compartment fuse box.
  3. Pull the relay straight out. It is held in by friction. You may need a small flathead screwdriver to gently pry it out, but usually your fingers are enough.
  4. Insert the new relay. Make sure it is oriented the same way as the old one. The pins on the bottom should match the socket pattern. Press it firmly into place.
  5. Replace the fuse box lid and close the hood.

Important: Always use a relay with the same amperage rating and pin configuration as the original. Using the wrong relay can cause overheating or electrical damage.

Where to Buy a Quality Replacement Fuel Pump for Your 2000 Toyota Camry

If you have tested the relay, fuses, and inertia switch, and the problem is still present, the fuel pump itself is likely the culprit. The fuel pump is the heart of your fuel system.
