2000 Infiniti I30 Fuel Pump Relay Location: A Complete Guide for DIY Owners

If you own a 2000 Infiniti I30 and are dealing with fuel delivery issues, here is the bottom line: the fuel pump relay is located behind the left kick panel, inside the passenger compartment, not in the engine compartment fuse box. Many owners start by looking under the hood, but the relay is actually tucked away near the driver's side footwell area. This guide walks you through exactly where to find it, how to test it, and what to do if the relay is not the problem.

Where Is the Fuel Pump Relay on a 2000 Infiniti I30?

The fuel pump relay on your 2000 Infiniti I30 is located behind the left kick panel. The left kick panel is the plastic trim piece on the driver's side, near your left foot when you are sitting in the driver's seat. To access it, you need to remove this trim panel. Here is how to do it:

Step 1: Remove the left kick panel trim. Look for a few plastic push pins or screws holding the panel in place. Use a trim removal tool or a flathead screwdriver to carefully pry them out. The panel should come off without too much force.

Step 2: Locate the relay. Once the panel is off, you will see a cluster of relays and wires. The fuel pump relay is typically one of the larger relays mounted in this area. It may be labeled on the relay box cover or on the relay itself.

Step 3: Identify the correct relay. If the relay is not labeled, refer to the diagram on the inside of the fuse box cover or consult your owner's manual. The fuel pump relay is usually a standard 4-pin or 5-pin relay, and it controls power to the fuel pump.

Why the Confusion About Location?

There is a common misconception that the fuel pump relay is in the engine compartment fuse box. Some sources mention that the relay is "in the engine compartment fuse box near the battery" for a 2000 Infiniti I30. However, the factory service manual and multiple repair guides clearly state that the fuel pump relay is behind the left kick panel. The engine compartment fuse box does contain many relays, such as the ABS motor relay, cooling fan relays, and the ECM relay, but the fuel pump relay is not among them.

The confusion likely comes from the fact that the fuel pump fuse is located in the engine compartment fuse box. The fuse and the relay are two different components. The fuse protects the circuit, while the relay is an electronic switch that controls when power flows to the pump. Always check the fuse first, but if the fuse is good and the pump still does not run, the relay is the next suspect.

How to Test the Fuel Pump Relay

Before replacing the relay, test it to confirm it is faulty. Here is a simple method:

1. Locate the relay. With the left kick panel removed, you can see the relay.

2. Listen for the prime cycle. Turn the ignition key to the "ON" position (do not start the engine). You should hear a faint humming sound from the fuel pump for about one second. This is the fuel pump priming the system. If you do not hear this sound, the relay or the pump may be bad.

3. Check for power. Use a multimeter to test the relay. With the ignition on, check for battery voltage at the relay's power terminals. You should see 12 volts. If there is no power, check the fuse and wiring.

4. Test the relay coil. Measure resistance across the relay's coil terminals. A good relay will show a resistance reading (typically 50 to 200 ohms). If the reading is infinite (open circuit), the relay is dead.

5. Perform a bench test. Remove the relay and apply 12 volts to the coil terminals. You should hear a clicking sound, and the relay should have continuity between the switched terminals.

Common Symptoms of a Bad Fuel Pump Relay

A failing fuel pump relay can cause several symptoms that mimic a bad fuel pump. Here are the most common signs:

No start condition. The engine cranks but will not fire. The fuel pump does not prime when you turn the key to "ON."

Intermittent stalling. The engine runs fine, then suddenly dies, especially when driving. After a few minutes, it may restart.

Engine cranks but no fuel pressure. You can check fuel pressure at the fuel rail. If there is no pressure, the relay or pump may be the issue.

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

Other Components to Check

If the relay tests good but the pump still does not run, there are a few other things to inspect:

Fuel pump fuse. The fuel pump fuse is located in the engine compartment fuse box, near the battery. It is typically a 10A or 15A fuse. Check it for continuity.

Fuel pump itself. The fuel pump is located inside the fuel tank. On the 2000 Infiniti I30, there is an access cover under the rear seat that allows you to reach the pump without dropping the fuel tank. You can check for voltage at the pump connector while someone turns the key to "ON." If you have voltage at the pump but no sound, the pump is bad.

Wiring and connectors. Over time, wiring can become damaged. One common issue is a pinched or cut wire to the fuel pump, especially after interior work or transmission service. Check the black and yellow wire that runs from the relay to the pump for any breaks or shorts.

ECM and sensors. The engine control module (ECM) controls the fuel pump relay. The ECM receives signals from the crankshaft position sensor and other sensors to determine when to activate the pump. If the sensor is faulty, the ECM may not tell the relay to turn on.

Step-by-Step Diagnostic Procedure

If you are troubleshooting a no-start condition, follow this logical sequence:

Step 1: Check the fuel pump fuse. Open the engine compartment fuse box and locate the fuel pump fuse. If it is blown, replace it and see if the problem returns. If it blows again, there is a short in the circuit.

Step 2: Listen for the prime cycle. Turn the key to "ON" and listen near the rear seat for a one-second hum. If you hear it, the relay and pump are likely working. If not, move to Step 3.

Step 3: Test the fuel pump relay. Remove the left kick panel, locate the relay, and test it as described above. If the relay is bad, replace it.

Step 4: Check for voltage at the pump. Remove the rear seat cushion and access the fuel pump connector. Have a helper turn the key to "ON" while you measure voltage at the connector. You should see battery voltage for about one second. If you have voltage but no pump sound, the pump is bad. If you have no voltage, the problem is in the wiring between the relay and the pump.

Step 5: Inspect wiring. Look for any damaged, pinched, or corroded wires, especially near the relay and along the path to the fuel tank.

Final Thoughts

Finding the fuel pump relay on a 2000 Infiniti I30 is straightforward once you know where to look. It is not in the engine bay — it is behind the left kick panel on the driver's side. If you are experiencing starting issues, always start with the easiest checks: the fuse and the relay. If those are good, move on to testing the pump itself.

Remember that the fuel pump relay is just one part of the fuel delivery system. The ECM controls the relay based on engine speed signals, so if the engine is not turning over properly, the relay may never activate. Always check the basics first, and do not overlook the wiring and connectors, as they are a common source of problems on older vehicles.
