2002 Honda CRV Fuel Pump Relay: Complete Guide to Location, Testing, and Replacement

The bottom line: The fuel pump relay on a 2002 Honda CR-V is located inside the passenger compartment fuse box, which is underneath the steering column on the driver's side. It is not in the engine bay. The relay is specifically labeled as the No. 17 FUEL PUMP (15A) fuse, but the actual relay that controls the fuel pump is the PGM-FI Main Relay 2 (also called the Fuel Pump Relay) located inside the same interior fuse/relay box. If your CR-V cranks but won't start, and you don't hear the fuel pump prime when you turn the key to the "ON" position, a faulty fuel pump relay or fuse is a likely cause. This guide will walk you through finding it, testing it, and replacing it, with a professional recommendation for your replacement parts.

Where is the 2002 Honda CRV Fuel Pump Relay?

Unlike many vehicles where the fuel pump relay is under the hood, Honda designed the 2002 CR-V with the fuel pump relay inside the cabin. The location is straightforward:

  1. Interior Fuse Box Location: The interior fuse/relay box is located underneath the steering column on the driver's side. To access it, simply pull the cover toward you to release the hinges.
  2. Identifying the Right Relay: The fuel pump relay is technically called the PGM-FI Main Relay 2. This relay is mounted on the lower part of the interior fuse/relay box. The PGM-FI Main Relay 1 is located at the top of the same box. Do not confuse the two.
  3. Related Fuse: The system also has a 15A fuse specifically for the fuel pump. According to the fuse box diagram, this is fuse No. 17 in the instrument panel fuse box, labeled "FUEL PUMP." If this fuse is blown, the fuel pump will not receive power.

Important Note: Some earlier or generic guides may suggest the relay is in the under-hood fuse box. For the 2002 model year, this is incorrect. The under-hood box contains the main fuses and relays for the engine cooling fans, headlights, and ABS, but the fuel pump relay for this specific year is confirmed to be in the interior box.

How to Test the 2002 CRV Fuel Pump Relay

Before you buy a new relay, you can test the existing one. This saves you time and money. Here are three simple methods:

Method 1: The "Swap" Test (Easiest)
The interior fuse box contains multiple relays that are identical. You can swap the fuel pump relay (PGM-FI Main Relay 2) with another relay of the same type, such as the rear wiper relay or another non-critical relay.

  • Remove the suspected fuel pump relay.
  • Remove a known-good relay with the same part number and pin configuration.
  • Install the known-good relay into the fuel pump slot.
  • Turn the ignition to "ON" (II). If you now hear the fuel pump prime or the engine starts, the old relay is faulty.

Method 2: The "Listen" Test

  • Sit in the driver's seat with the doors and windows closed.
  • Turn the ignition key to the "ON" position (do not start the engine).
  • Listen carefully. You should hear a faint whirring or buzzing sound for about 2 seconds from the rear of the vehicle. This is the fuel pump in the gas tank pressurizing the system.
  • If you hear no sound, the fuel pump relay, the fuel pump fuse (No. 17), or the fuel pump itself may be bad.

Method 3: The "Jumper Wire" Test (Drain Gas or Bypass)
This method is primarily used to drain the gas tank, but it also confirms the relay is the issue. Caution: This generates sparks. Only do this in a well-ventilated area away from any flames or sparks.

  • Locate the fuel pump relay in the interior fuse box.
  • Remove the relay.
  • Using a short piece of wire, jumper the power and pump terminals in the relay socket (consult a wiring diagram for your specific pinout).
  • Turn the ignition to "ON." The fuel pump will run continuously. If the pump runs with the jumper but not with the relay installed, the relay is definitely bad.

How to Replace the 2002 Honda CRV Fuel Pump Relay

Replacing the relay is a simple do-it-yourself task that requires no special tools.

  1. Locate and Remove: Open the interior fuse box cover under the steering column. Identify the PGM-FI Main Relay 2. Grip the relay firmly and pull it straight out of its socket.
  2. Install the New Relay: Align the new relay with the socket (it will only fit one way due to the pin configuration). Press it firmly into place until it clicks.
  3. Test the Repair: Reinstall the fuse box cover. Turn the ignition key to the "ON" position. You should now hear the fuel pump prime for 2 seconds. Start the engine to confirm the repair.

The OEM Part Number for the 2002 CRV Fuel Pump Relay
If you are looking for a direct replacement, the genuine Honda part number for the 2002 CR-V fuel pump relay is 39794-S5A-003. This part is also compatible with several other Honda models from the early 2000s, including the 2002-2006 Honda Civic and 2003-2006 Honda Element.
