2001 Hyundai Tiburon Fuel Pump Relay Location: The Complete Guide to Finding and Fixing It

The bottom line: The fuel pump relay on a 2001 Hyundai Tiburon is located in the engine compartment fuse box, also known as the junction box. If your Tiburon cranks but won't start, the fuel pump relay is one of the first things you should check. This guide will walk you through exactly where to find it, how to test it, and what to do if it's bad.

Where Is the Fuel Pump Relay Located on a 2001 Hyundai Tiburon?

The fuel pump relay on a 2001 Hyundai Tiburon is located inside the engine compartment fuse box. This fuse box is a black plastic rectangular box situated near the battery on the driver's side of the engine bay. Open the fuse box cover and look for a relay labeled "Fuel Pump" or consult the diagram printed on the underside of the cover for the exact position. The relay is a small, square electronic component that plugs into the fuse box .

How to Test the Fuel Pump Relay on a 2001 Hyundai Tiburon

Before you assume the fuel pump is bad, testing the relay is a quick and easy step. A faulty relay is a common cause of a no-start condition because it cuts power to the fuel pump. Here is how to test it:

  1. Locate the relay. Open the engine compartment fuse box and find the fuel pump relay. Refer to the diagram on the fuse box cover. .
  2. Listen for the click. With the relay still in place, have a helper turn the ignition key to the "ON" position (do not start the engine). You should hear an audible click from the relay. This click indicates the relay is receiving power and is attempting to engage . If you hear no click, the relay may not be getting power, or the relay itself is defective.
  3. Swap the relay. The easiest way to test a relay is to swap it with an identical relay in the same fuse box. For example, you can swap the horn relay or the A/C relay with the fuel pump relay. If the car starts after the swap, the original fuel pump relay is bad and needs to be replaced .
  4. Use a multimeter. If you have a multimeter, you can test the relay for continuity. Remove the relay. Apply 12V power to the relay's coil terminals (usually pins 85 and 86). If the relay is working, you should hear a click, and the multimeter will show continuity between the switched terminals (usually pins 30 and 87). If there is no continuity, the relay is faulty .

Symptoms of a Bad Fuel Pump Relay on a 2001 Hyundai Tiburon

A failing fuel pump relay can cause a variety of driveability issues. If you experience any of the following symptoms, the relay is a prime suspect:

  • Engine Cranks But Won't Start: This is the most common symptom. You turn the key, the engine turns over, but it never fires up. This usually means the fuel pump is not receiving power to pressurize the fuel system .
  • No Fuel Pump Prime Noise: When you turn the ignition key to the "ON" position, you should hear a faint whirring or humming sound from the rear of the car for about 2-3 seconds. This is the fuel pump priming the system. If you don't hear this sound, the relay or the pump itself is likely not working .
  • Engine Stalls While Driving: A failing relay can intermittently cut power to the fuel pump, causing the engine to stall unexpectedly while you are driving. This is a dangerous condition that needs immediate attention .
  • Engine Starts Then Dies Immediately: The relay might provide power to the pump at startup but fail to keep the circuit closed. This results in the engine starting for a second and then dying.
  • Check Engine Light: A faulty relay can trigger a check engine light, often with codes related to a fuel pump circuit malfunction or low fuel pressure.

How to Replace the Fuel Pump Relay on a 2001 Hyundai Tiburon

Replacing the fuel pump relay is a simple job that anyone can do with no tools. Here are the steps:

  1. Locate the relay. Open the engine compartment fuse box and find the fuel pump relay .
  2. Remove the old relay. Simply pull the old relay straight out of its socket.
  3. Install the new relay. Push the new relay firmly into the same socket until it clicks into place.
  4. Test the repair. Turn the ignition key to the "ON" position and listen for the fuel pump to prime. If you hear it, try starting the engine.

What If the Relay Is Good But the Fuel Pump Still Doesn't Work?

If you have tested the relay and it is working correctly, but the fuel pump is still not running, the problem is likely elsewhere. Do not assume the entire fuel pump is bad without checking these other common causes:

  • Blown Fuel Pump Fuse: Check the fuel pump fuse in the same engine compartment fuse box. A blown fuse is a common and cheap fix. If the fuse blows again immediately after replacement, there is a short in the wiring or the fuel pump motor is failing .
  • Faulty Fuel Pump: The fuel pump itself may have failed. On a 2001 Hyundai Tiburon, the fuel pump is located inside the fuel tank. You can access it by removing the rear seat cushion. To replace the pump, you must first relieve the fuel system pressure, disconnect the battery, and then remove the fuel pump assembly from the top of the tank .
  • Wiring Issues: A broken wire, corroded connector, or a poor ground connection between the relay and the fuel pump can prevent the pump from running. Inspect the wiring harness under the rear seat and near the fuel tank.
  • Faulty Crank Sensor or ECM: The engine control module (ECM) uses the signal from the crank position sensor to activate the fuel pump relay. If the crank sensor is bad, the engine will crank but the pump will not run.
