2001 Hyundai Accent Fuel Pump Relay: Location, Testing, and Replacement Guide
The fuel pump relay on a 2001 Hyundai Accent is located in the engine compartment fuse box, and if your car cranks but won’t start, this relay is often the first component to check. This small but critical electrical part controls power to the fuel pump, and troubleshooting it is a straightforward DIY task that can save you time and money. Below, we walk you through everything you need to know about locating, testing, and replacing the fuel pump relay on your 2001 Hyundai Accent, along with practical tips for ensuring your fuel system stays reliable.
Where Is the Fuel Pump Relay on a 2001 Hyundai Accent?
The fuel pump relay on the 2001 Hyundai Accent (2nd generation) is located in the engine compartment fuse box . This fuse box is a black plastic box situated near the battery, on the driver’s side of the engine bay. To access it:
- Open the hood and secure it with the prop rod.
- Locate the black fuse box cover. It typically has a diagram printed on the inside of the lid.
- Remove the cover by pressing the tabs on the sides.
- Look for the relay labeled “FUEL PUMP” or “FUEL” in the diagram. In many 2001 Accent models, the fuel pump relay is the third relay from the front in the fuse box .
If the diagram is missing or faded, you can also identify the relay by its size and shape: it is a standard 4-pin relay, usually square or rectangular, and it may be the same type as other relays in the box (like the horn or headlight relay) .
Note: Some 2001 Accent models may have a second fuse box inside the cabin, but the fuel pump relay is always under the hood. Double-check your owner’s manual or the fuse box cover for the exact layout.
Common Symptoms of a Failing Fuel Pump Relay
A faulty fuel pump relay can cause several noticeable problems. Here are the most common symptoms:
- Engine cranks but won’t start: This is the classic sign. The starter motor turns over the engine, but the fuel pump doesn’t receive power, so no fuel reaches the cylinders .
- No fuel pump priming noise: When you turn the ignition key to the “ON” position (without starting), you should hear a brief humming sound from the fuel pump near the rear of the car. If you hear nothing, the relay may be dead .
- Intermittent stalling: A failing relay may work sometimes and fail others, causing the engine to die unexpectedly while driving. This is a safety hazard and should be addressed immediately .
- Check Engine Light illuminates: The car’s computer may detect a loss of fuel pressure and trigger a diagnostic trouble code (DTC) related to the fuel system .
If you experience any of these issues, start with the fuel pump relay—it’s much cheaper and easier to replace than the fuel pump itself.
How to Test the Fuel Pump Relay
Testing the relay is simple and requires only a few basic tools: a multimeter (set to Ohms or continuity mode) and a 12V power source (like a car battery or a power supply). Follow these steps:
- Remove the relay: Gently pull it straight out of the fuse box socket. It may be tight, but it will come out with a steady pull.
- Identify the pins: A standard 4-pin relay has two pins for the control circuit (coil) and two pins for the power circuit (switch). On most relays, pins 85 and 86 are the coil, and pins 87 and 30 are the switch .
- Test the coil resistance: Set your multimeter to Ohms (Ω). Touch the probes to pins 85 and 86. A good relay will show a resistance reading between 50 and 120 ohms (depending on the relay). If you get an open circuit (OL) or 0 ohms, the coil is bad .
- Test the switch continuity: With the relay unpowered, touch the probes to pins 87 and 30. The multimeter should show no continuity (OL) because the switch is normally open .
- Apply power to the coil: Connect a 12V source to pins 85 and 86 (polarity doesn’t matter for a relay). You should hear a click as the switch closes.
- Re-test the switch: With power applied, touch the probes to pins 87 and 30 again. This time, the multimeter should show continuity (near 0 ohms). If it doesn’t, the relay is defective .
If the relay fails any of these tests, replace it.
How to Replace the Fuel Pump Relay
Replacing the fuel pump relay on a 2001 Hyundai Accent is a 5-minute job:
- Buy a replacement relay: You can purchase a compatible relay at any auto parts store (like AutoZone, O’Reilly, or Advance Auto Parts) or online. The part number is typically HYUNDAI 95200-2D000 or an equivalent aftermarket part. Make sure it matches the pin configuration (4-pin, 30A rating) .
- Remove the old relay: As described above, pull it straight out of the socket.
- Install the new relay: Align the pins with the socket and push it firmly into place. It should click in securely.
- Test the system: Turn the ignition to the “ON” position. Listen for the fuel pump priming sound (a few seconds of humming). Then try to start the engine. If it starts, the job is done.
Important: If the new relay also fails quickly, or if the fuel pump doesn’t run even with a good relay, the problem may be deeper—such as a faulty fuel pump, a bad ground connection, or a wiring issue .
Could It Be Something Else?
If the fuel pump relay tests good, the issue may lie elsewhere in the fuel system. Common culprits include:
- Fuel pump fuse: Check the fuse box for a blown fuse labeled “FUEL PUMP” or “IG COIL” (typically 15A or 20A). Replace it if blown .
- Fuel pump itself: The pump may be worn out or seized. A mechanic can test fuel pressure at the rail to confirm .
- Wiring or connector problems: Corroded or loose wires between the relay and the fuel pump can interrupt power. Inspect the harness under the car and near the fuel tank .
- Engine control unit (ECU) issues: Although rare, a faulty ECU can fail to trigger the relay. This requires a diagnostic scan tool to check.
