1995 Acura Legend Fuel Pump Relay Location: The Complete Guide to Finding, Testing, and Replacing It

The fuel pump relay on a 1995 Acura Legend is located in the main under-hood fuse box, which sits on the driver’s side of the engine bay, near the battery. This relay controls power to the fuel pump and is a common failure point that can cause a no-start condition. If your Legend cranks but won’t start, the fuel pump relay is one of the first things to check. This guide walks you through the exact location, how to test it, and how to replace it without any special tools.

The 1995 Acura Legend is a reliable luxury sedan, but after three decades on the road, electrical components like the fuel pump relay can fail. The relay is a small, rectangular device that acts as a switch, sending power from the battery to the fuel pump when the engine is cranking or running. When it goes bad, your fuel pump won’t activate, and the engine will crank without starting. Knowing where to find it and how to test it can save you time and money at a repair shop.

1. Exact Location of the 1995 Acura Legend Fuel Pump Relay

The fuel pump relay is located in the main under-hood fuse and relay box. Here are the detailed steps to find it:

  • Open the hood. The hood release latch is under the dashboard on the driver’s side. Pull it, then release the secondary latch under the front edge of the hood.
  • Look at the driver’s side of the engine bay. You’ll see a black plastic box with a cover, usually near the battery. This is the main fuse and relay box.
  • Remove the cover. The cover has clips on the sides. Press them and lift the cover straight up. The inside of the cover often has a diagram showing the location of each relay and fuse. If the diagram is missing or faded, check the owner’s manual.
  • Find the relay labeled “Fuel Pump” or “PGM FI Main Relay.” On the 1995 Acura Legend, the fuel pump relay is often part of a larger unit called the PGM FI Main Relay. This relay is usually located in the top row of relays, closest to the front of the car. It’s a square or rectangular relay with a gray or black casing. The PGM FI Main Relay controls both the fuel pump and the fuel injectors, so if this relay fails, the engine won’t start or run.

Note: Some 1995 Acura Legend models have the fuel pump relay separate from the PGM FI relay. In those cases, it’s still in the same fuse box, but it’s a smaller relay with a label like “Fuel Pump” or “FP.” If you don’t see a separate fuel pump relay, the PGM FI Main Relay is the one you need to check.

2. How to Test the 1995 Acura Legend Fuel Pump Relay

Before you buy a new relay, you can test the existing one to confirm it’s faulty. You’ll need a multimeter (available at any auto parts store for under $20) and a 12-volt test light. Here’s how to do it:

Step 1: Listen for the fuel pump

  • Turn the ignition key to the ON position (but don’t start the engine). You should hear a brief whirring sound from the fuel pump for about 2 seconds. This sound comes from the rear of the car, near the fuel tank. If you don’t hear it, the relay or the fuel pump might be dead.

Step 2: Check for power at the relay

  • With the ignition off, remove the PGM FI Main Relay or the fuel pump relay from the fuse box.
  • Set your multimeter to DC voltage (20V range).
  • Place the black probe on a good ground (like a bolt on the engine block or a clean metal surface).
  • With the ignition key in the ON position, touch the red probe to the terminal in the fuse box socket that corresponds to the relay’s power input. You should see 12 volts at that terminal. If not, the problem is a blown fuse or a wiring issue.

Step 3: Test the relay itself

  • The relay has four or five pins. The two smaller pins are the coil (control circuit), and the two larger pins are the switch (power circuit). You can find the pin layout in the owner’s manual or online.
  • Set your multimeter to ohms (resistance).
  • Touch the probes to the two coil pins. You should see a resistance reading between 50 and 200 ohms (this varies by relay). If you see infinite resistance (OL), the coil is open and the relay is bad.
  • For the switch pins, you should see infinite resistance when the relay is not energized. Then, apply 12 volts to the coil pins (using a battery or a power source). You should hear a click, and the switch pins should now show 0 ohms (closed circuit). If you don’t hear a click or the resistance doesn’t change, the relay is faulty.

3. How to Replace the 1995 Acura Legend Fuel Pump Relay

Replacing the fuel pump relay on your 1995 Acura Legend is a straightforward job that takes about 10 minutes. Here’s what you need:

  • A new fuel pump relay or PGM FI Main Relay. You can buy this from an auto parts store like AutoZone, O’Reilly Auto Parts, or online. The part number for the PGM FI Main Relay is often 39760-SL0-A01 or 39760-SL0-A02. Check with the parts store to confirm fitment.
  • A flathead screwdriver or trim tool. You might need this to pry the relay out of the socket.

Steps:

  1. Disconnect the negative battery cable. This prevents any electrical short or accidental spark.
  2. Remove the old relay. Grab the relay firmly and pull it straight up. If it’s stuck, use a small flathead screwdriver to gently pry it out. Be careful not to damage the socket.
  3. Insert the new relay. Line up the pins with the socket and push it down firmly until it clicks into place. Make sure it’s seated properly.
  4. Reconnect the battery cable.
  5. Test the new relay. Turn the ignition to the ON position and listen for the fuel pump to prime. If you hear it, the relay is working. If not, double-check the installation or check the fuses.

4. Common Symptoms of a Bad Fuel Pump Relay on a 1995 Acura Legend

If you’re not sure whether the relay is the problem, look for these signs:

  • Engine cranks but won’t start. This is the most common symptom. The starter turns the engine over, but the fuel pump doesn’t send fuel.
  • No fuel pump priming sound. When you turn the key to the ON position, you should hear a short whirring sound from the rear of the car. If you don’t hear it, the relay or pump is dead.
  • Engine stalls while driving. A failing relay can cause the fuel pump to lose power intermittently, which makes the engine cut out.
  • Check Engine Light comes on. The engine control unit (ECU) will store a code related to the fuel pump circuit. You can read the code with a OBD-I scanner (the 1995 Legend uses a 3-pin connector under the dashboard).
  • Car won’t start after sitting. A bad relay may work when cold but fail when hot, or vice versa.

5. Other Possible Causes When the Legend Won’t Start

If the fuel pump relay tests good, don’t assume the job is done. The 1995 Acura Legend has a few other common issues that can cause a no-start condition:

  • Blown fuel pump fuse. The fuse is in the same under-hood fuse box. Check fuse #7 (15-amp) or the fuse labeled “Fuel Pump.” If it’s blown, replace it and see if it blows again. If it does, there’s a short in the wiring.
  • Faulty fuel pump. The fuel pump itself can wear out. On the 1995 Legend, the fuel pump is located inside the fuel tank. If you hear the relay click but no pump sound, the pump might be dead. You can test it by applying 12 volts directly to the pump connector at the tank.
  • Bad main relay. The PGM FI Main Relay (which includes the fuel pump relay) is a known weak point on Honda and Acura vehicles of this era. The solder joints inside the relay can crack over time, causing intermittent failure. You can often fix this by re-soldering the joints, but it’s easier to replace the whole relay.
  • Ignition switch problems. The ignition switch can wear out and fail to send power to the fuel pump relay. If the relay clicks but the pump doesn’t run, check for 12 volts at the relay’s output terminal.
  • Security system issues. The 1995 Acura Legend has a factory security system that can disable the fuel pump if it’s triggered. If the security light is flashing, try resetting the system by disconnecting the battery for 10 minutes.

6. How to Access the Fuel Pump Relay Without a Diagram

If you lost the fuse box cover diagram or the owner’s manual, you can still find the fuel pump relay by following these steps:

  • Look for the largest relay in the fuse box. The fuel pump relay is often one of the bigger relays (around 1.5 inches square). On the 1995 Acura Legend, it’s usually the second or third relay from the front.
  • Check the color. The PGM FI Main Relay is typically black or dark gray. Other relays, like the horn relay or cooling fan relay, are often different colors.
  • Use a test light. With the ignition ON, probe each relay socket. The fuel pump relay socket should have one terminal with 12 volts that stays on, and another terminal that shows 12 volts only when the engine is cranking. This is the relay’s output to the fuel pump.
  • Google the part number. If you can read a number on the relay (like “39760-SL0-A01”), search that number online. You’ll find diagrams and guides for your specific model.

7. Preventing Future Fuel Pump Relay Issues

The fuel pump relay on a 1995 Acura Legend is a cheap part, but it can leave you stranded. Here’s how to avoid that:

  • Replace the relay every 5 years. Even if it’s working, the relay’s internal contacts can wear out. A new relay costs less than $30 and takes 10 minutes to install.
  • Keep a spare relay in the glove box. If you’re on a road trip and the relay fails, you can swap it in a few minutes. This is a common trick among Acura and Honda owners.
  • Check the battery and charging system. A weak battery or failing alternator can cause voltage spikes that damage the relay. Ensure your battery terminals are clean and tight, and test the alternator output (should be around 14 volts with the engine running).
  • Inspect the wiring. Look for chafed or cracked wires near the fuse box. Heat and vibration can damage the insulation, leading to shorts.
