1996 Toyota Camry Fuel Pump Relay: Location, Testing, and Replacement Guide

If your 1996 Toyota Camry cranks but won’t start, the fuel pump relay—technically called the circuit opening relay—is one of the most common culprits. This relay controls power to the fuel pump, and when it fails, the pump won’t receive electricity, leaving you stranded. The good news: this relay is easy to locate, test, and replace, often fixing the problem without needing a new fuel pump. In this guide, we’ll walk you through everything you need to know about the 1996 Toyota Camry fuel pump relay, from where it’s hiding to how to test it and what to do if it’s bad.

Where Is the Fuel Pump Relay on a 1996 Toyota Camry?

The fuel pump relay on a 1996 Toyota Camry is located behind the glove box, on the passenger side of the dashboard. To access it, you’ll need to remove the glove box completely. Once you pull the glove box out, look up toward the opening: you’ll see a small relay block mounted above the glove box area. This block typically contains three relays in a row. The fuel pump relay is the middle one.

Toyota officially calls this relay the “Circuit Opening Relay” (part number 90987-02009 or equivalent). It sits in Relay Block (R/B) 6, which is located above the glove box. This relay is responsible for completing the electrical circuit to the fuel pump, allowing it to run when the engine is cranking or running.

Important note: There is also an EFI Main Relay located in the engine compartment fuse box (Junction Block 2, on the left inner fender). The EFI main relay powers the entire engine control system, while the circuit opening relay specifically controls the fuel pump. Don’t confuse the two.

How the Fuel Pump Relay Works in a 1996 Camry

Understanding the fuel pump relay’s job helps you diagnose problems faster. Here’s the basic flow:

1. When you turn the ignition key to the ON position, the EFI Main Relay energizes, providing power to the engine control computer.
2. The computer then sends a signal to the circuit opening relay (fuel pump relay).
3. The circuit opening relay closes, sending battery voltage to the fuel pump inside the gas tank.
4. The fuel pump pressurizes the fuel system, allowing the engine to start and run.

The circuit opening relay also has a safety feature: if the engine stalls or the key is turned off, the relay opens, cutting power to the fuel pump. This prevents the pump from running continuously if there’s an accident or electrical fault.

Symptoms of a Bad Fuel Pump Relay

A failing fuel pump relay on a 1996 Toyota Camry can cause several symptoms. Recognizing these early can save you time and money:

1. Engine Cranks But Won’t Start
This is the most common symptom. You turn the key, the starter motor spins the engine over, but it never fires up. You may hear the fuel pump prime for 1-2 seconds when you first turn the key to ON; if you don’t hear that whirring sound from the rear of the car, the relay or pump isn’t getting power.

2. Intermittent Stalling
If the relay is failing internally, it may work sometimes and fail others. Your Camry might start fine one day, then stall out while driving, especially after hitting a bump. This is a strong indicator of a relay with worn contacts.

3. No Fuel Pump Prime Noise
When you turn the key to the ON position (without cranking), you should hear a brief humming sound from the fuel tank area. If you don’t hear anything, the relay could be stuck open, or the pump itself is dead.

4. Check Engine Light with Code P1233
On OBD-II equipped 1996 Camrys, a failing fuel pump relay or driver module can trigger trouble code P1233 (Fuel Pump Driver Module Disabled or Off Line). This code indicates the computer has lost communication with the fuel pump control circuit.

How to Test the 1996 Camry Fuel Pump Relay

Before replacing the relay, you can test it with a simple multimeter. Here’s a step-by-step method:

Step 1: Locate the Relay
Remove the glove box and find the middle relay in the block above the opening. Pull it out carefully.

Step 2: Identify the Relay Pins
The relay has 4 or 5 pins. Toyota relays typically use a pin layout with numbers 1, 2, 3, and 5 (or 30, 85, 86, 87). You can check the relay’s body for a diagram.

Step 3: Test the Coil (Pins 1 and 2 or 85 and 86)
Set your multimeter to ohms (Ω). Touch the probes to pins 1 and 2 (or 85 and 86 on Bosch-style relays). You should get a reading between 60 and 120 ohms. If the reading is infinite (open circuit), the relay coil is burned out and needs replacement.

Step 4: Test the Switch Contacts (Pins 3 and 5 or 30 and 87)
With the relay unpowered, the switch contacts should be open (infinite resistance). If you read any continuity here, the relay is stuck closed and should be replaced.

Step 5: Apply Power to the Coil
Connect a 12V battery or power source to pins 1 and 2 (85 and 86). You should hear a click. Now, measure resistance between pins 3 and 5 (30 and 87). The reading should drop to 0 ohms (continuity). If the relay doesn’t click or the contacts don’t close, replace it.

Quick Bypass Test:
To quickly check if the relay is the problem, you can jump the relay socket. With the relay removed, carefully connect a jumper wire between the FP (Fuel Pump) and +B (Battery) terminals in the relay socket. Turn the key to ON. If the fuel pump runs (you’ll hear it), the relay is bad. If the pump still doesn’t run, the issue is likely the pump itself, a fuse, or wiring.

Common Causes of Fuel Pump Relay Failure

Fuel pump relays don’t fail often, but when they do, it’s usually due to:

• Age and wear: The relay’s internal contacts can corrode or burn out over time, especially after 20+ years of use.
• Voltage spikes: Electrical surges from the alternator or battery can damage the relay coil.
• Moisture and heat: The relay block behind the glove box can get warm, and humidity can cause corrosion on the relay terminals.
• Poor electrical connections: The relay socket itself can develop loose or corroded pins, mimicking a bad relay.

How to Replace the Fuel Pump Relay

Replacing the 1996 Toyota Camry fuel pump relay is a straightforward DIY job. Here’s what to do:

1. Buy the correct relay: The OEM part number is 90987-02009 or 90084-98009. You can also use the SU003-00522 or 90987-02010 as a replacement. Aftermarket relays are available and typically cost $15–$30.

2. Disconnect the battery: This is a safety precaution to avoid any electrical shorts.

3. Remove the old relay: Pull the relay straight out of its socket. It may require a gentle wiggle.

4. Install the new relay: Push the new relay firmly into the same socket. Make sure it’s fully seated.

5. Reconnect the battery and test: Turn the key to ON and listen for the fuel pump prime. If you hear it, the relay is working.

6. Reinstall the glove box: Push the glove box back into place and secure it.

Other Related Fuel Pump Components to Check

If replacing the relay doesn’t solve your problem, there are a few other components to inspect:

Fuel Pump Fuse (AM2 30A)
The fuel pump circuit is protected by a 30-amp AM2 fuse located in the main fuse box under the hood. If this fuse is blown, the fuel pump won’t run. Check it with a multimeter or visually.

EFI Main Relay
This relay is located in the engine compartment fuse box, on the left inner fender near the battery. It powers the engine control system. If it fails, the computer won’t turn on, and the fuel pump relay won’t get its signal. Test it the same way as the fuel pump relay.

Fuel Pump Itself
If the relay and fuses are good, the fuel pump inside the gas tank may be dead. On a 1996 Camry, the fuel pump is located inside the fuel tank, accessible by removing the rear seat cushion and a cover plate. You can test for power at the pump connector using a test light.

Wiring and Connectors
Check the wiring harness from the relay block to the fuel pump. Look for broken wires, corrosion, or loose connections, especially at the relay socket itself. Faulty factory crimps at the relay box have been known to cause issues.

Expert Tips for Diagnosing Fuel Pump Issues

1. Use the diagnostic connector: Under the hood, there is a small diagnostic connector (usually near the fuse box). If you jumper the FP and +B terminals with a piece of wire, the fuel pump should run continuously with the key on. This bypasses all relays and tells you if the pump is functional.

2. Listen for the pump: With the key on, have someone sit in the back seat. The fuel pump is under the rear seat cushion. If you hear a faint buzzing or whirring, the pump is getting power.

3. Check fuel pressure: A fuel pressure gauge connected to the fuel rail should read 2.5–3.0 bar (36–44 psi) with the key on and engine off. If pressure is low or zero, the pump or relay is the issue.

4. Swap relays: If you have another relay of the same type (like the horn relay), you can swap it temporarily to see if the fuel pump starts working. This is a quick diagnostic trick.

Why the Fuel Pump Relay Matters More Than You Think

The 1996 Toyota Camry is a reliable car, but its fuel system components are aging. The circuit opening relay is a small, inexpensive part that can cause a big headache if it fails. Many DIY mechanics replace the fuel pump unnecessarily when the real problem is a $20 relay. By understanding how to locate, test, and replace this relay, you can save hundreds of dollars in repair costs.

A final word of caution: The fuel system remains under pressure even after the engine is off. Before disconnecting any fuel lines, relieve the pressure by removing the fuel cap and the fuel pump fuse, then cranking the engine for a few seconds. Always work in a well-ventilated area and avoid sparks or open flames.
