07 GSXR 600 Fuel Pump Relay Location: A Complete Troubleshooting Guide for Riders

If your 2007 Suzuki GSX-R 600 won’t start and you don’t hear the fuel pump prime when you turn the key, the fuel pump relay is one of the first things you need to check. The fuel pump relay on a 2007 GSXR 600 is located on the right front side of the airbox, inside a black plastic clip that holds two relays side by side. This small but critical component acts as a switch that directs battery power to the fuel pump when the ignition is turned on, and if it fails, the pump simply won’t activate. Understanding exactly where this relay is and how to test it can save you hours of frustration and unnecessary part swapping.

Where Exactly Is the Fuel Pump Relay on a 07 GSXR 600?

The relay is mounted on the top right of the airbox when you’re sitting on the bike. There are two identical black relay boxes clipped into rubber grommets on the airbox—one on the left side and one on the right side. The one you need is the one on the right. To access it, you’ll need to remove the fuel tank. Once the tank is lifted or removed, look at the front of the airbox. The relay is clipped into a small bracket and is about the size of a typical automotive relay. Some riders also describe it as a “nipple thing” under the gas tank connected to the airbox via a rubber grommet.

Why Your Fuel Pump Might Not Be Getting Power

Before you dive into replacing parts, it helps to understand the common causes of a no-power-to-fuel-pump situation on these bikes. The 2007 GSXR 600 has a few known weak points that can cause this issue.

The fuel pump relay itself is a common failure point. You can test it easily with a multimeter. The relay should have 12 volts at the Yellow/Red wire to the Black/White wire at the pump, but only during priming or when cranking. If you’re only getting 5 volts at the pump connector, that’s a clear sign something is wrong in the circuit.

The tip-over sensor is another frequent culprit. This sensor is mounted on the very rear of the subframe. If it’s not mounted correctly, or if it’s been dislodged, it can prevent the fuel pump from priming. One rider reported that simply flicking the sensor gently or ensuring it was properly oriented solved the problem. The bike may throw a C23 code for the tip-over sensor if this is the issue.

The ECU and wiring harness can also cause problems. There have been cases where the orange inserts inside the ECU connector were misaligned, preventing proper contact. Another common mistake is swapping the STVA (Secondary Throttle Valve Actuator) plug with the fuel pump plug—they look similar, and if they’re reversed, the pump won’t run. Some riders have also found that the gear position sensor, if unplugged, will prevent the bike from knowing it’s in neutral, which can stop the fuel pump from priming.

How to Test the Fuel Pump Relay Step by Step

Testing the relay is straightforward and doesn’t require any special tools beyond a multimeter. Here’s what you need to do.

1. Locate and remove the relay. After removing the tank, unclip the right-side relay from the airbox.
2. Check for insulation between terminals. Using a multimeter set to continuity mode, test between terminals “A” and “B” on the relay. There should be no continuity (infinite resistance) when no power is applied.
3. Apply 12 volts to the coil. Connect the positive lead of a 12V battery to terminal “C” and the negative to terminal “D.” When you do this, you should hear a click, and then continuity should exist between terminals “A” and “B.”
4. Check the voltage at the relay connector. With the ignition on, check for 12V at the Yellow/Blue wire and the Red/Blue wire at the relay socket. The Yellow/Blue wire should be hot nearly all the time. The ECM grounds the relay to activate it, so the voltage will drop when the relay is activated.

If the relay fails any of these tests, replace it with a new one. The correct OEM part number for the fuel pump relay is 38740-24X50, which is compatible with many Suzuki models including the GSXR 600 from 1997 through 2019.

Other Common Causes of Fuel Pump Failure

Sometimes the relay is fine, but the problem lies elsewhere. Here are a few more things to check before you give up.

Check the fuses. The fuel pump relay gets its power from the ignition circuit, so check both the fuel pump fuse and the ignition fuse. The main fuse is 30A, and there are several 10A and 15A fuses in the fuse box.

Inspect all connections. Corroded or loose connections are “silent assassins” of fuel pump relay functionality. Even a microscopic layer of oxidation on a relay pin can introduce enough resistance to disrupt the electrical signal. Make sure all relay pins and wires are clean and securely connected.

The fuel pump itself could be bad. The OEM part number for the stock fuel pump is 15100-24H00, which operates at a pressure range of 38-43 psi. If you’ve tested the relay and the wiring, and you’re still not getting power to the pump, the pump may need replacement.

When to Replace the Fuel Pump Instead of the Relay

If you’ve confirmed the relay is working, the fuses are good, and the wiring is intact, the problem is likely the fuel pump itself. A failing pump may show symptoms like intermittent priming, weak pressure, or no response at all. In some cases, the bike will start if you hard-wire the pump directly to the battery, but it won’t run when connected through the normal circuit.
