1997 Toyota Camry Fuel Pump Relay Location: The Complete Guide to Finding, Testing, and Replacing It

The bottom line: The fuel pump relay on a 1997 Toyota Camry is located in the engine compartment fuse box, also known as the under-hood relay box. It is typically the EFI (Electronic Fuel Injection) relay or the Circuit Opening Relay, sitting right next to the main fuse block on the driver's side near the battery. If your Camry cranks but won't start, or if you hear no humming sound from the fuel tank when you turn the key to the "ON" position, this relay is the first thing you should check.

Why You Need to Know the Fuel Pump Relay Location

The fuel pump relay is a small electrical switch that controls power to the fuel pump. When you turn the ignition key, the relay closes and sends battery voltage to the fuel pump, allowing it to pressurize the fuel system. If this relay fails, the fuel pump won't run, and your engine will starve for fuel.

For a 1997 Toyota Camry, the fuel pump relay is a common failure point due to age, heat, and vibration. Knowing exactly where it is can save you a trip to the mechanic and a lot of money. The relay itself costs around $15 to $30, while a shop might charge you $100 or more just for diagnosis.

Exact Location of the Fuel Pump Relay

Under the hood, driver's side. Open the hood of your 1997 Toyota Camry. Look at the fuse and relay box on the driver's side, near the battery. This is a black plastic box with a removable lid.

Inside the relay box. Remove the lid by pressing the tabs on the sides. On the underside of the lid, you will find a diagram that shows the location of each relay and fuse. The fuel pump relay is labeled as "EFI" or "Circuit Opening" . It is usually a square, dark gray or black relay, typically about 1 inch by 1 inch in size.

Specific position. On most 1997 Camry models, the EFI relay is located in the front row of the relay box, closest to the radiator. There are usually two similar-looking relays side by side. One is the EFI main relay, and the other is the fuel pump relay. If you are unsure, check the diagram on the lid.

Important note: Some 1997 Camry models have the fuel pump relay integrated into the engine compartment fuse box near the positive battery terminal. If you don't find it in the main relay box, check the small fuse box attached directly to the battery.

How to Test the Fuel Pump Relay

Before you buy a new relay, you can test the old one to confirm it is bad. Here is a simple step-by-step process:

Step 1: Listen for the fuel pump. Turn the ignition key to the "ON" position (do not start the engine). Have someone stand near the fuel tank. If you hear a faint humming or whirring sound for about 2 to 3 seconds, the fuel pump relay is working. If you hear nothing, the relay may be faulty.

Step 2: Locate the relay. Remove the relay from the fuse box. It pulls straight out. You may need a small flathead screwdriver to gently pry it out.

Step 3: Visual inspection. Look at the relay terminals. If you see corrosion, rust, or burn marks, replace the relay immediately.

Step 4: Swap test. The easiest test is to find an identical relay in the same fuse box. The EFI relay and the HORN relay are often the same type. Swap the fuel pump relay with the horn relay. Then turn the key to the "ON" position. If the fuel pump now runs, your original relay is bad. If the horn stops working, the problem is not the relay.

Step 5: Multimeter test (advanced). Use a digital multimeter set to measure resistance (ohms). Check the resistance between terminals 85 and 86. You should see a reading between 50 and 120 ohms. If the reading is open (OL) or very high, the relay coil is burnt out.

Common Symptoms of a Bad Fuel Pump Relay

You don't need to wait for a complete failure. These symptoms tell you the relay is going bad:

1. Engine cranks but won't start. This is the most common symptom. The starter motor turns the engine over, but the engine never fires up because no fuel is reaching the injectors.

2. No fuel pump priming sound. When you turn the key to "ON," you should hear a brief hum from the rear of the vehicle. If you hear nothing, the relay is not sending power to the pump.

3. Intermittent starting problems. The car starts fine sometimes, but other times it refuses to start. This is a classic sign of a failing relay that is making intermittent contact.

4. Engine stalls while driving. If the relay fails while the car is running, the engine will die suddenly. You may be able to restart it after a few minutes once the relay cools down.

5. Check Engine Light (CEL) comes on. A faulty fuel pump relay can trigger diagnostic trouble codes (DTCs) related to the fuel system, such as P0230 (fuel pump primary circuit malfunction).

How to Replace the Fuel Pump Relay

Replacing the fuel pump relay on a 1997 Toyota Camry is one of the easiest DIY repairs you can do. No special tools are required.

Step 1: Safety first. Make sure the engine is off and the key is out of the ignition. Disconnect the negative battery cable to prevent any accidental short circuits.

Step 2: Remove the old relay. Locate the relay in the under-hood fuse box. Grasp it firmly and pull it straight up. It should come out with a light tug. If it is stuck, use a small screwdriver to gently pry it out.

Step 3: Install the new relay. Push the new relay into the same socket. Make sure it clicks into place and is fully seated. The relay is directional, but the pins are designed so it can only go in one way.

Step 4: Reconnect the battery. Reattach the negative battery cable and tighten the terminal.

Step 5: Test the repair. Turn the key to the "ON" position. Listen for the fuel pump priming sound from the rear of the car. Then start the engine. If it starts and runs smoothly, the repair is complete.

Common Mistakes to Avoid

Mistake 1: Replacing the fuel pump first. Many people assume a no-start condition is caused by a bad fuel pump. But the pump itself is much more expensive and harder to replace than the relay. Always test the relay first.

Mistake 2: Using the wrong relay. Not all relays are the same. Some have different amperage ratings. Always use a relay that matches the original specifications. A standard 30-amp relay is usually correct for the 1997 Camry.

Mistake 3: Ignoring the fuse. The fuel pump circuit also has a fuse. If the fuse is blown, the relay won't help. Check the "EFI" or "FUEL PUMP" fuse in the same fuse box before replacing the relay.

Mistake 4: Buying a cheap relay. Low-quality relays can fail quickly. Stick with reputable brands for reliability.
