1992 HONDA CIVIC FUEL PUMP FUSE LOCATION: HERE'S WHERE TO FIND AND FIX IT

The fuel pump fuse for your 1992 Honda Civic (all models: DX, LX, VX, Si) is located in the UNDER-HOOD main fuse and relay box. Specifically, it is identified as Fuse #6 (15 Amps) inside the gray or black rectangular box found near the driver's side fender in the engine compartment. Always ensure the ignition is completely OFF and the key is removed before touching any fuses.

Knowing where this crucial fuse lives is often the first and simplest step to diagnosing a non-starting Civic. If the engine cranks but won’t fire, a blown fuel pump fuse is a common culprit. This guide provides detailed, model-specific instructions to locate, check, and replace it safely and efficiently, along with essential troubleshooting steps.

What You Need (Gather Before Starting):

  • Work Gloves: Protect your hands from sharp edges or hot surfaces if the engine ran recently. Allow at least 30 minutes for cooling.
  • Flashlight/Work Light: Crucial for clearly seeing the fuse box and its diagram in the engine bay shadows.
  • Needle-Nose Pliers or Fuse Puller: Your primary tool for safely extracting fuses. Plastic fuse pullers are inexpensive and minimize damage risk.
  • Multimeter (Optional but Recommended): The most reliable tool for definitively testing fuse continuity (functionality). Fuses can appear intact visually but still be faulty.
  • Replacement Fuse: 15 Amp, Mini Low-Profile Blade type (Standard ATO or "ATM" size). Using a different rating is dangerous. Always carry genuine Honda or high-quality spares (Bussmann, Littelfuse).
  • Owner's Manual (Optional): Useful if present, though this guide provides precise Civic-specific instructions.

Step 1: Locating the Main Under-Hood Fuse & Relay Box

  1. Park Safely: Engage the parking brake firmly. Place the transmission in Park (Automatic) or 1st/Reverse (Manual). Ensure the Civic is on level ground away from traffic.
  2. Open the Hood: Release the interior hood latch near your lower left knee while seated. Move to the front grille, reach underneath the center of the hood, find and lift the secondary safety latch, then raise the hood fully. Secure it with the provided prop rod.
  3. Identify the Box: Stand facing the front of your Civic. Look near the top of the driver's side fender (left side when facing forward). You will see a rectangular, grey or black plastic box. This is the main power distribution center.
  4. Access the Cover: The box has a protective lid secured by simple plastic clips or clasps. Locate the clips (usually one or two along the front edge). Push the clips inward or upward (gentle pressure) and lift the lid straight up. Set the lid aside carefully. DO NOT force it; damaged clips render the box vulnerable.

Step 2: Finding Fuse #6 (15A Fuel Pump Fuse)

  1. Locate the Diagram: Inspect the underside of the fuse box lid you just removed. It always contains a clear layout diagram showing the position and function of every fuse and relay inside. Diagrams can fade; use your flashlight.
  2. Identify "FUEL PUMP" or "FP": Systematically scan the diagram. You are looking for the listing for the "FUEL PUMP" fuse. It is almost always labeled "FP" near its position on the map. Crucially, note its position number. For ALL 1992 Civics (DX, LX, VX, Si), the Fuel Pump fuse is consistently labeled as Fuse #6 in this under-hood box.
  3. Match Location in the Box: Look down into the opened fuse box. Find the actual Fuse #6. Positions are usually numbered on the fuse box plastic itself near the fuse slots or can be counted based on the lid's diagram reference point. Focus only on the fuse section for now (relays are larger square components). Fuse #6 is a 15A mini blade fuse in the lower row section of the box.
  4. Visual Confirmation: Confirm you've found the blue 15A fuse labeled "FUEL PUMP" or "#6" per the diagram. Double-check that this corresponds exactly to your lid diagram before proceeding.

Step 3: Removing the Fuel Pump Fuse (#6)

  1. Ensure Ignition OFF: Verify the ignition key is fully removed. If recently running, wait 30 minutes minimum for components to cool.
  2. Grip Firmly: Position your fuse puller or needle-nose pliers vertically over the top of the Fuse #6 plastic body.
  3. Pull Straight Up: Apply steady, even, vertical pressure upwards. Avoid rocking or twisting, which can damage the fuse terminals or the box socket. The fuse should release cleanly. If stuck, gently wiggle with minimal horizontal force.
  4. Inspect Extracted Fuse: Hold the fuse securely in your hand or place it on a clean, non-conductive surface like a cloth.

Step 4: Testing the Fuse (#6)

Visual Inspection:

  • Examine the small, visible metal strip inside the plastic fuse body spanning between the two blades.
  • A GOOD fuse shows an unbroken, continuous metal element.
  • A BLOWN fuse shows a clearly melted, severed, or gapped metal strip. Significant discoloration (brown/black) inside the plastic often accompanies a failure. Visual inspection is NOT foolproof!

Multimeter Verification (Strongly Recommended):

  • Set Multimeter: Turn dial to continuity test mode (symbol resembling sound waves) or the lowest Ohms (Ω) range.
  • Zero the Meter: Touch probes together. Should beep (continuity) or show near 0 Ω (resistance). If using resistance, note this baseline reading.
  • Test Fuse: Touch one probe firmly to each of the fuse's metal blades simultaneously.
  • Interpret Results:
    • Continuity Mode: A clear, constant beep indicates a GOOD fuse (continuous path).
    • Resistance Mode: A reading very close to 0 Ohms (e.g., 0.2Ω - 1Ω) indicates a GOOD fuse.
    • NO beep (continuity) or a reading of "OL" (Over Limit) or very high resistance (like 1 MΩ or higher) indicates a BAD (blown) fuse. This is definitive proof.

Step 5: Replacing a Blown Fuel Pump Fuse (#6)

  1. Get Correct Replacement: Confirm you have the exact type: 15 Amp, Mini Low-Profile Blade (ATM). NEVER substitute a higher amp fuse (risk of wire fire) or lower amp fuse (will blow prematurely).
  2. Align the Blades: Position the new fuse so its blades align perfectly vertical with the open slots in socket #6.
  3. Insert Firmly: Press the fuse downward into the socket using steady thumb pressure until it seats fully and feels secure. You should feel it clip into place. Avoid hammering or using tools that can crack plastic. The top surface should be flush with surrounding fuses.
  4. Dispose of Old Fuse: Properly discard the blown fuse. It should never be reused.

Step 6: Testing the Repair & Initial Troubleshooting

  1. Reinstall Lid: Ensure no tools or debris are in the box. Align the fuse box lid and press down firmly until all clips audibly click into a locked position.
  2. Turn Ignition ON (Do Not Start): Insert key, turn to "ON" (II) position. Listen intently near the rear of the car (fuel tank area under rear seat) for a distinct 2-3 second humming/whirring sound. This confirms the fuel pump is receiving power and priming the system correctly. If you hear this sound, attempt to start the engine.
  3. Engine Start Attempt: Turn key to "START" (III) position. The engine should crank normally. A successful start indicates the blown fuse was the primary issue.

What If It Blows Again Immediately?

If the new fuse blows as soon as you turn the ignition to "ON" (before even starting) or immediately after starting the engine, STOP. This indicates a serious short circuit in the fuel pump circuit. Do not keep replacing fuses. Driving or continued attempts risks significant damage or fire.

Investigate these critical areas immediately:

  1. Inspect Wiring Harness: Visually trace the harness running from the under-hood fuse box back to the firewall bulkhead connector. Check for sections where wiring might have rubbed through insulation against sharp metal edges (common near strut towers, battery tray, under fuse box mount), melted near exhaust components, or been damaged by rodents.
  2. Check Main Relay: While distinct from the fuse, the nearby Main Relay (PGM-FI Relay) controls power to the fuel pump fuse. A short inside this relay can cause the fuse to blow. Listen for a distinct click when turning ignition ON; no click often points to relay failure. Replacement location is covered below.
  3. Fuel Pump Itself: A failing fuel pump motor drawing excessive current (internal short) is a common cause of repeated fuse blowing. Requires rear seat removal and fuel pump access panel removal for direct testing (voltage/power at pump connector) or replacement. Suspect this if fuse blows only after engine starts/runs briefly.
  4. Professional Diagnosis: Given the fire risk with electrical shorts, seeking a qualified Honda technician with diagnostic tools is the safest and most efficient approach. They can pinpoint the short's location using fused test circuits.

Crucial Component: The Main Relay (PGM-FI Relay)

  • Function: This critical relay powers both the fuel pump circuit (triggering Fuse #6) and the Civic's ECU (Engine Control Unit). A failure prevents the fuel pump from running at all, mimicking a blown fuel pump fuse symptom (crank/no start).
  • Location: Mounted inside the cabin, under the driver's side dashboard. Left of the steering column, secured by a metal bracket attached to a dash support beam. Access often requires removing the driver's side lower dash panel (knee bolster) held by Phillips screws.
  • Identification: A blue or gray/brown plastic box approx. 1.5" x 1.5" with multiple electrical pins underneath. Labeled "PGM-FI".
  • Failure Symptoms: Intermittent no-start (especially when engine bay hot - "Honda Main Relay Syndrome"), cranks but no prime sound, blown Fuel Pump fuse sometimes accompanies severe relay failure. Tapping the relay firmly when attempting to start a non-starting car was a common temp fix indicating pending failure.

Where Spare Fuses Are Hiding (1992 Civic)

Your Civic comes equipped with spare fuses for emergencies:

  1. Under-Hood Box Lid: Check small clips or holders molded directly into the underside of the main under-hood fuse box lid itself. Several spare mini fuses (including 15A blues) should be present.
  2. Driver's Side Interior Fuse Box: Located near the lower left edge of the dashboard, below the instrument cluster (near hood release). Open the small plastic access panel. Spare fuses are often stored in dedicated slots within the box, near its hinges or corners, separate from the active fuses.

FAQs: Addressing Real-World Civic Owner Concerns

  • "My under-hood diagram is faded/missing!" Go by position #6. Confirm it's a 15A mini fuse (blue). Compare fuse sizes to adjacent labeled fuses (e.g., Headlight - likely large 30/40A, Radio - smaller 10/15A).
  • "Are fuses different for DX, LX, VX, Si?" No. Fuse location #6 is standardized across all 1992 Civic models for the fuel pump circuit.
  • "My Civic has aftermarket alarms/stereos. Could that affect it?" Absolutely. Poorly installed aftermarket equipment tapping into ignition or fuel pump wiring is a major cause of shorts and blown fuses. Scrutinize any non-factory wiring mods, especially near fuse/relay panels and ignition switch.
  • "What's the actual fuel pump replacement cost?" Part cost: 350 (quality brands like Denso, ACDelco). Labor: 2-4 hours (450), depending on rear seat access difficulty, tank condition, and shop rates. Total: $500+.
  • "Is there a way to disable the fuel pump?" Disconnecting Fuse #6 while the engine is running will kill the engine instantly, acting as a safety cut-off. Reinstall only when needed to restart. Consider installing a fused, switched fuel pump cut-off relay for persistent electrical faults.

Key Takeaways for Your 1992 Honda Civic

  • The 15A Fuel Pump Fuse (#6) resides in the under-hood main fuse box, driver's side, near the fender. Its function is clearly indicated by the lid diagram and fuse position labeling.
  • Never ignore a repeated blown Fuse #6. It signals a dangerous electrical short demanding immediate diagnosis. Forced driving risks extensive damage.
  • Keep quality 15A mini blade spares handy. Utilize the storage locations under the hood fuse box lid or inside the driver's dash fuse box.
