Where is the fuel pump relay located in a Honda Civic?

Under the left side of the dashboard. Below is relevant information about the Civic: 1. Introduction: The Honda Civic comes in three-door hatchback, hardtop coupe, hybrid, and five-door sedan versions. The Honda Civic launched in China shares the same production platform as Dongfeng Honda's existing model, the Honda CR-V. 2. Exterior: The new Civic largely maintains the styling of overseas models, featuring full LED headlights. The side profile design is bolder than the front, with a gently sloping C-pillar resembling a coupe, and adopts "bracket-style" LED taillights with a dart-shaped light cluster.

Last month, I just helped my friend fix the fuel pump relay issue on his 10th-gen Civic. It's mainly hidden in two locations: one is in the engine compartment fuse box, where the yellow relay is for the fuel pump; the other is under the dashboard. You'll need to crouch down and feel towards the lower left side of the steering wheel, where there's a plastic cover hiding the driver-side fuse box. When searching, look for the small fuel pump icon and relay number (usually labeled as position 15) printed on the fuse box. You can replace it with needle-nose pliers. Remember to disconnect the power before starting, and be cautious with older cars as the clips tend to become brittle. For older Civics from 2006-2011, it might be hidden even deeper, requiring the glove box to be removed for access.

Insights from auto repair experience: The fuel pump relay location in Civics varies by generation. For newer models like the 10th-gen Civic, it's typically hidden behind the interior panel above the driver's left knee—just remove the cover and look for the blue or black relay next to the 30A fuse. If there's absolutely no fuel pump humming sound during startup, using a multimeter to test the relay socket contacts for continuity is quicker. Last year, while repairing a flood-damaged car, I discovered that a rusty relay base caused poor contact—temporarily bypassing it with jumper wires proved very practical for emergency driving. If you can't locate it, there's a crude method: with the engine running, pull out relays one by one—the one that causes the engine to stall when removed is your target.

Actually, the Civic owner's manual includes a relay location diagram in the fuse and relay section. In most cases, you need to pry open the small square cover on the left side of the dashboard, and you can see a gray box about the size of a matchbox by lying down. Look for relay number 46 (taking the tenth generation as an example), which is slightly smaller than a matchbox and has metal legs. Remember to disconnect the power before checking, and be careful not to break the plastic clips when disassembling older cars. For models after 2016, some relays have been relocated behind the glove box, requiring the removal of two screws. Always turn off the engine and remove the key before working on it—the fuel pump circuit is no joke.

There are three methods to test the fuel pump relay: 1) Listen for a two-second buzzing sound during startup, 2) Check if the fault code is P0627 (Fuel Pump Control Circuit), and 3) Test whether terminals 30-87 conduct when terminals 85-86 are powered. The relay is specifically located behind the interior trim panel on the left side of the steering column—its cover can be pried open with a fingernail. It's recommended to prepare a T20 Torx screwdriver and a flashlight, as the black relay box in some model years is particularly tricky to access. DIY replacement costs only thirty bucks—don’t fall for the repair shop’s upsell to replace the entire assembly.

Quick Guide for Beginners: Open the driver's door and squat down, then extend your head into the space above the brake pedal. Reach your left hand upwards to the left. Once you feel a plastic panel with grilles, apply slight force to pry it open. Inside, you'll find a compartment resembling a power strip—this is the fuse box. Look for a small square marked with a yellow lightning symbol (the fuel pump relay is the only one with this lightning mark). For the 10th-gen Civic, it's position 46; for the 8th-gen, it's the ECU relay in position 6. Note: On the 2018 model, you'll need to remove the storage compartment to see it. Safety tip: Wear goggles—last time I did this, a metal shard got into my eye. Recommended spare fuses: stock up on 20A and 30A sizes.
