1995 Honda Del Sol Fuel Pump Relay Location: A Complete Guide for DIY Owners

The bottom line: The 1995 Honda Del Sol fuel pump relay is located inside the main under-dash fuse box, positioned on the driver’s side of the vehicle, near the left kick panel. This relay is a critical component that controls power to the fuel pump, and if your Del Sol cranks but won’t start, or stalls after a few seconds, the fuel pump relay is often the first thing to check. Knowing exactly where to find it and how to test it can save you time, money, and a tow truck visit.

Why the Fuel Pump Relay Matters

The fuel pump relay is an electrical switch that sends power to the fuel pump when you turn the ignition key. Without it, the fuel pump won’t run, and your engine won’t get the fuel it needs to start or keep running. In the 1995 Honda Del Sol, this relay is a small, rectangular box with four or five prongs, and it plugs into the fuse box like a larger fuse. When it fails, you may hear a clicking sound from the relay area, but the fuel pump stays silent.

Understanding the 1995 Honda Del Sol Electrical System

The 1995 Honda Del Sol shares its electrical architecture with the 1995 Honda Civic, which means the fuel pump relay location is consistent across both models. The under-dash fuse box, also called the main fuse box or junction box, is mounted on the driver’s side, behind the plastic panel near the footwell. Inside this box, you’ll find fuses for various systems, along with several relays. The fuel pump relay is typically labeled as “Fuel Pump” or “PGM FI Main Relay” depending on the exact configuration. Some owners refer to it as the main relay because it controls both the fuel pump and the engine control unit (ECU) power.

Step-by-Step Guide to Locate the Fuel Pump Relay

  1. Park your car safely. Make sure the engine is off, the key is removed, and the parking brake is engaged. You’ll be working under the dashboard on the driver’s side.

  2. Remove the lower dash panel. Look under the steering column, on the left side of the driver’s footwell. There’s a plastic cover held in place by two or three plastic clips or screws. Use a flathead screwdriver or a trim removal tool to gently pry off the panel. Be careful not to crack the plastic.

  3. Locate the main fuse box. Once the panel is removed, you’ll see a rectangular black box with a lid. This is the main under-dash fuse box. It’s usually mounted vertically against the firewall, near the left kick panel.

  4. Open the fuse box lid. The lid may have a diagram printed on the inside showing where each fuse and relay is located. If the diagram is faded or missing, look for a small rectangle that is larger than the surrounding fuses. That’s the relay.

  5. Identify the fuel pump relay. In the 1995 Del Sol, the fuel pump relay is often the one closest to the firewall, on the top row of the fuse box. It’s a square or rectangular component with four or five metal prongs on the bottom. Some models use a single main relay that controls both the fuel pump and the ECU. This relay is usually gray or black, about 1 inch wide and 1.5 inches tall.

  6. Check the label. If you’re unsure, look for a small sticker or embossed marking on the fuse box plastic that says “FUEL PUMP” or “PGM FI.” The PGM FI main relay is the most common part name for this component in Honda Del Sols.

How to Test the Fuel Pump Relay

Once you’ve found the relay, testing it is straightforward. You don’t need special tools, just a multimeter or a test light.

  1. Remove the relay. Grip the relay firmly and pull it straight out of the socket. It may require a little wiggling, but it should come out without force.

  2. Inspect the prongs. Look for any corrosion, bent pins, or melted plastic. If the relay looks damaged, replace it immediately.

  3. Test for continuity. Set your multimeter to the ohms setting (Ω). Touch the probes to the relay’s coil terminals (usually the two outermost prongs). A good relay will show a reading between 50 and 120 ohms. If you get infinite resistance (OL), the coil is open and the relay is dead.

  4. Test the switch function. Apply 12 volts to the coil terminals using a battery or a power source. You should hear a click, and the switch terminals (the other two prongs) should show continuity (0 ohms). If no click happens, or the switch doesn’t close, the relay is faulty.

  5. Swap test. If you don’t have a multimeter, the easiest way to test is to swap the suspect relay with an identical relay from the same fuse box, like the horn or headlight relay. If the car starts after swapping, the relay is the problem.

Common Symptoms of a Bad Fuel Pump Relay

  • Engine cranks but won’t start. This is the most common sign. The starter turns the engine over, but the fuel pump never gets power, so no fuel reaches the injectors.
  • Car starts then dies after a few seconds. Sometimes the relay works initially but fails after the engine starts, cutting power to the fuel pump.
  • No prime sound. When you turn the key to the “ON” position (without starting), you should hear a brief whirring sound from the fuel tank area for about 2 seconds. If you don’t hear this, the relay or pump is not working.
  • Intermittent stalling. The engine may run fine for a while, then suddenly stall while driving, especially over bumps. This points to a loose or failing relay.
  • Clicking noise from the fuse box. If you hear a rapid clicking sound from under the dash, it could mean the relay is trying to engage but failing.

Replacing the Fuel Pump Relay

Replacing the relay is a simple DIY job that takes about 10 minutes.

  1. Buy the right part. The 1995 Honda Del Sol uses a PGM FI main relay (part number 39760-SR3-003 or equivalent). You can find this at any auto parts store or online. Make sure it matches the shape and pin configuration of your original relay.

  2. Unplug the old relay. Pull it straight out of the socket. No tools are needed.

  3. Plug in the new relay. Align the prongs with the socket and push it in firmly until it clicks into place.

  4. Test the car. Turn the key to the ON position and listen for the fuel pump prime sound. Then start the engine. If it starts and runs smoothly, the repair is complete.

  5. Reinstall the lower dash panel. Snap the plastic cover back into place and secure any clips or screws.

Why the Fuel Pump Relay Fails

The fuel pump relay is an electromechanical component, meaning it has moving parts inside. Over time, the internal contacts wear out, burn, or stick due to heat, vibration, and age. In a 1995 Del Sol, the relay is over 30 years old, so failure is common. Moisture from the footwell area can also cause corrosion on the relay pins or inside the socket. If you live in a humid climate, this is a more frequent issue.

How to Prevent Future Relay Problems

  • Keep the fuse box dry. If you notice water leaks under the dashboard, fix them immediately. Check the windshield seal and door seals.
  • Use dielectric grease. Apply a small amount of dielectric grease to the relay prongs before inserting it. This prevents corrosion and improves electrical contact.
  • Replace the relay as a preventive measure. If you’re planning a long road trip or your Del Sol has over 150,000 miles, consider replacing the fuel pump relay before it fails. It’s cheap insurance.
  • Avoid cheap aftermarket relays. Stick to OEM or high-quality aftermarket parts. Cheap relays may have poor internal components and fail sooner.

What to Do If the Relay Isn’t the Problem

If you’ve tested and replaced the fuel pump relay, but the car still won’t start, the issue could be elsewhere. Check these components:

  • Fuel pump itself. The pump may be dead. Listen for the prime sound from the tank. If you don’t hear it, test the pump power directly with a multimeter.
  • Fuel pump fuse. There is a separate fuse for the fuel pump in the under-hood fuse box. Check it first.
  • Main relay wiring. Look for broken wires or corroded connectors between the relay and the fuel pump.
  • Ignition switch. A worn ignition switch can fail to send power to the relay.
  • Engine ground. A bad ground can cause the relay to not work properly.

Cost of Replacing the Fuel Pump Relay

A new PGM FI main relay for a 1995 Honda Del Sol typically costs between $20 and $50 at auto parts stores. Online prices are similar. If you take it to a mechanic, labor might add $50 to $100, but the job is so easy that most DIY owners do it themselves. Total cost: under $50 for parts and 10 minutes of your time.
