1992 Honda Accord Fuel Pump Fuse Location: The Complete Guide to Finding and Fixing It

If your 1992 Honda Accord cranks but won't start, the fuel pump fuse is one of the first things you should check. The fuel pump fuse for a 1992 Honda Accord is located in the engine compartment fuse box, not inside the cabin. Specifically, it is fuse number 33, a 10-amp fuse that protects the PGM-FI Main Relay, which in turn powers the fuel pump. Before you start replacing expensive parts like the fuel pump itself, spend five minutes checking this fuse. It could save you hundreds of dollars and a lot of frustration.

Understanding the 1992 Honda Accord Fuel System

The 1992 Honda Accord belongs to the fourth generation (CB7/CB9 chassis) and uses a fuel injection system managed by the PGM-FI (Programmed Fuel Injection) control unit. The fuel pump is electric and located inside the fuel tank. It does not run continuously. When you turn the ignition key to the ON position, the fuel pump should prime for about two seconds and then shut off. If the engine does not start, the pump will only run again once the engine is cranking or running.

The electrical path for the fuel pump goes through several components: the battery, the ignition switch, the PGM-FI Main Relay, the fuel pump fuse, and finally the fuel pump itself. If any of these components fail, the fuel pump will not receive power. The fuel pump fuse is the easiest and cheapest component to check first.

Where Is the 1992 Honda Accord Fuel Pump Fuse Located?

The fuel pump fuse is not in the interior fuse box under the dashboard. It is located in the engine compartment fuse box on the passenger side of the engine bay, near the battery.

Here is exactly how to find it:

  1. Open the hood and secure it properly.
  2. Look for a black plastic fuse box located near the battery on the passenger side. It is usually rectangular and has a cover that snaps off.
  3. Remove the cover by pressing the tabs on the sides.
  4. Look at the diagram on the underside of the cover or refer to the owner's manual. The fuse you need is fuse number 33.
  5. Fuse number 33 is a 10-amp fuse labeled "PGM-FI Main Relay". This fuse protects the main relay that controls the fuel pump, the ECU, and the automatic transmission control unit.

Important: Some diagrams show the fuse box layout with fuse numbers 1 through 39. Fuse number 33 is specifically listed as a 10-amp fuse for the PGM-FI Main Relay. Do not confuse this with the interior fuse box, which has a different layout and does not contain the fuel pump fuse.

How to Test the Fuel Pump Fuse

Testing a fuse is simple and requires no special tools, though a multimeter or a test light makes it easier.

Visual inspection: Pull the fuse out using the plastic fuse puller tool usually found inside the fuse box cover. Hold the fuse up to the light. Look through the transparent plastic body. If the metal strip inside is broken or melted, the fuse is blown.

Multimeter test: Set your multimeter to measure continuity (the symbol that looks like a sound wave). Touch one probe to each of the two metal prongs on the top of the fuse. If you hear a beep or see a reading close to zero, the fuse is good. If you get no reading, the fuse is blown.

Test light method: With the fuse still installed, touch the test light probe to each of the two small metal contact points on the top of the fuse. If the test light illuminates on both sides, the fuse is good. If it lights on only one side, the fuse is blown.

What If the Fuse Is Good?

If the fuel pump fuse (fuse number 33) is good, but you still have no fuel pressure and cannot hear the fuel pump run for two seconds when you turn the key, the problem is likely the PGM-FI Main Relay. This is a common failure point on the 1992 Honda Accord.

The PGM-FI Main Relay is located behind the left side of the dashboard, above the interior fuse box. It is a gray or black relay with multiple pins. The relay provides power to the fuel pump, the ECU, and the fuel injectors. Over time, the solder joints inside the relay can crack due to heat and vibration, causing the relay to fail.

How to test the main relay: When you turn the ignition key to the ON position, you should hear a faint click from behind the dashboard. If you hear the click but the fuel pump does not run, the relay may be partially failed. If you do not hear any click, the relay is likely dead. You can also try tapping the relay gently with a screwdriver handle while a helper turns the key. If the engine starts, the relay is bad and needs to be replaced.

Other Possible Causes of No Fuel Pressure

If both the fuse and the main relay are good, the problem may be elsewhere. Here are other things to check:

  1. Fuel pump itself: The electric motor inside the fuel pump may have failed. On the 1992 Accord, the fuel pump is located inside the fuel tank. You can test for power at the fuel pump connector under the rear seat. If you have power at the pump but no fuel pressure, the pump is likely dead.

  2. Fuel pump ground: The fuel pump needs a good ground connection. A corroded or loose ground wire can prevent the pump from running.

  3. Ignition switch: The ignition switch supplies power to the fuel pump circuit. If the switch is worn out, it may not send power to the relay.

  4. Blown engine compartment fuse number 18: Fuse number 18 is a 50-amp fuse for the ignition switch. If this fuse is blown, the ignition switch will not send power to the fuel pump relay.

Step-by-Step Troubleshooting Guide

Follow these steps in order to diagnose a no-start condition caused by a fuel pump issue on your 1992 Honda Accord:

  1. Check fuse number 33 (10-amp) in the engine compartment fuse box. This is the PGM-FI Main Relay fuse. If blown, replace it with a new 10-amp fuse. If it blows again immediately, there is a short circuit somewhere in the wiring.

  2. Listen for the fuel pump prime. Turn the key to the ON position (do not crank the engine). Listen near the rear of the car for a humming sound from the fuel tank. You should hear it for about two seconds. If you hear nothing, proceed to step 3.

  3. Check the PGM-FI Main Relay. Locate the relay behind the left side of the dashboard. Have a helper turn the key to ON while you listen for a click. If you hear no click, replace the relay.

  4. Check for power at the fuel pump. Remove the rear seat cushion. You will find an access panel on the floor under the carpet. Remove the panel to access the fuel pump electrical connector. With the key ON, use a test light or multimeter to check for 12 volts at the connector. If you have power, the pump is likely bad. If you have no power, there is a wiring problem between the relay and the pump.

  5. Check the engine compartment fuse number 18 (50-amp). This fuse protects the ignition switch. If it is blown, the entire ignition system may be dead.

Preventing Future Fuel Pump Issues

Once you get your 1992 Honda Accord running again, there are a few simple things you can do to prevent future fuel pump problems:

  • Keep the fuel tank at least a quarter full. Running the tank low frequently can cause the fuel pump to overheat because the fuel in the tank helps cool the pump.
  • Replace the fuel filter regularly. A clogged fuel filter puts extra strain on the fuel pump, causing it to work harder and fail sooner.
  • Use quality fuel. Poor quality fuel can contain contaminants that damage the fuel pump over time.
  • Address check engine lights promptly. If the check engine light comes on, have the code read. Some codes relate to fuel system issues that can be fixed before they lead to pump failure.
