2017 Honda Pilot Fuel Pump: Complete Guide to Symptoms, Diagnosis, and Replacement

If you own a 2017 Honda Pilot, the most important thing to know about your fuel pump is that it is a critical component that can fail without much warning. When it goes bad, your Pilot will either struggle to start, hesitate during acceleration, or stall while driving. The fuel pump for a 2017 Honda Pilot is located inside the fuel tank, and replacing it is an intermediate-level DIY job that typically costs between $250 and $650 for parts if you do it yourself, compared to $800 to $1,400 at a professional shop . This guide covers everything you need to know—from symptoms and diagnosis to step-by-step replacement and the best replacement options on the market.

Understanding the 2017 Honda Pilot Fuel Pump

The 2017 Honda Pilot uses a fuel injection system that requires a specific fuel pressure range for proper operation. For a 2017 Honda Pilot, the fuel pressure should be in the range of 50-60 psi . The fuel pump is responsible for drawing fuel from the tank and delivering it to the engine at this pressure. When the pump starts to fail, the engine does not get the right amount of fuel, which leads to performance problems.

The 2017 Honda Pilot comes with two different fuel pump components: the low-pressure fuel pump module inside the tank (part number 17045-TZ5-A10, replaced by 17045-TZ5-A11) and a high-pressure fuel pump located near the engine (part number 16790-RLV-305) . The high-pressure pump is used in the direct injection system found on the 3.5L V6 engine. Depending on which pump fails, the symptoms and repair process will differ.

Common Symptoms of a Failing Fuel Pump

Recognizing the early signs of a failing fuel pump can save you from being stranded on the side of the road. Here are the most common symptoms to watch for:

  1. Engine Cranks but Won't Start – This is the most obvious sign. If you turn the key and the engine cranks over but refuses to fire, the fuel pump may not be delivering fuel to the engine. However, this can also be caused by a blown fuse, a bad relay, or a clogged fuel filter.

  2. Whining Noise from the Fuel Tank – A healthy fuel pump makes a quiet humming sound when you turn the ignition to the ON position. If you hear a loud whining or screeching noise coming from the rear of the vehicle near the fuel tank, the pump is likely failing due to worn bearings or contamination.

  3. Hesitation or Surging During Acceleration – If your Pilot hesitates when you press the gas pedal, or if the engine surges forward unexpectedly, the fuel pump may be unable to maintain consistent pressure. This is especially noticeable when driving uphill or carrying a heavy load.

  4. Loss of Power Under Load – When the fuel pump cannot deliver enough fuel, the engine will feel sluggish, especially when you try to accelerate quickly or climb a hill. This is a common symptom of a pump that is wearing out but not yet completely dead.

  5. Engine Stalling – If the fuel pump fails intermittently, the engine may stall without warning, particularly at low speeds or when idling. This is dangerous, especially in traffic, and requires immediate attention.

  6. Check Engine Light – The check engine light may illuminate, and you may see diagnostic trouble codes like P0087 (fuel rail/system pressure too low) or P0191 (fuel rail pressure sensor range/performance problem) . Using an OBD-II scanner to check for these codes can help narrow down the issue before you begin any repair work.

Diagnosing the Problem

Before you replace the fuel pump, it is important to confirm that the pump is actually the problem. Here is how to diagnose a 2017 Honda Pilot fuel pump issue.

Step 1: Check the Fuel Pump Fuse and Relay – Start with the easiest check. Locate the fuel pump fuse in the under-hood fuse box. Use a fuse puller to remove it and inspect it for a broken wire. If the fuse is blown, replace it and see if the problem goes away. If the fuse blows again, there is a short circuit in the wiring.

Step 2: Listen for the Pump – Turn the ignition to the ON position without starting the engine. You should hear a quiet humming sound from the rear of the vehicle for about 2-3 seconds as the pump primes the system. If you hear nothing, the pump is likely not receiving power or has failed.

Step 3: Check Fuel Pressure – Connect a fuel pressure gauge to the fuel rail service port. Turn the ignition to the ON position and check the reading. For a 2017 Honda Pilot, the fuel pressure should be in the range of 50-60 psi . If the pressure is below specifications, the fuel pump may be failing, or the fuel filter could be clogged. If the pressure rises but then drops quickly after the pump stops, the check valve inside the pump assembly may be leaking.

Step 4: Scan for Trouble Codes – Use an OBD-II scanner to check for diagnostic trouble codes. Common codes associated with fuel pump problems include P0087 and P0191 . These codes can help narrow down the issue before you begin any repair work.

Where Is the Fuel Pump Located?

The fuel pump on a 2017 Honda Pilot is located inside the fuel tank, which is mounted beneath the vehicle in the rear area. To access it, you typically need to remove the second-row seat or fold it forward, then peel back the carpet to reveal a metal access cover . For most Honda Pilot models from 2016 to 2023, the access panel is located under the rear seat cushion in the cargo area. After removing the seat, you will find a metal plate secured with screws or bolts. Removing this plate gives you direct access to the top of the fuel pump module .

Step-by-Step Fuel Pump Replacement

Replacing the fuel pump in a 2017 Honda Pilot is an intermediate-level DIY job that takes approximately 1.5 to 3 hours. Below is the complete step-by-step procedure.

Tools and Parts You Will Need:

  • Safety glasses and nitrile gloves
  • Class B fire extinguisher
  • Floor jack and jack stands
  • Wheel chocks
  • Trim clip remover tool
  • Ratchet with 10mm and 12mm sockets
  • Torque wrench
  • Phillips screwdriver
  • Pick tool
  • Fuel line disconnect tool set
  • Fuel pump lock ring wrench or brass punch with dead-blow hammer
  • Shop towels and drain pan
  • Flashlight
  • Replacement fuel pump module assembly
  • Fuel pump module seal/O-ring
  • Fuel line quick-connect O-rings
  • Dielectric grease

Safety Precautions – Before you begin any work on the fuel system, it is essential to follow safety precautions. Fuel vapors are highly flammable, so no smoking, sparks, or open flames should be present in the work area. Work in a well-ventilated space and keep a fire extinguisher nearby. Always disconnect the 12-volt battery negative terminal before unplugging the pump electrical connector. Use a brass punch or a fuel pump lock ring tool instead of steel tools to avoid creating sparks .

Step 1: Relieve Fuel System Pressure – Start by opening the fuel filler door and loosening the gas cap to vent the tank. In the under-hood fuse and relay box, locate and remove the fuel pump fuse or relay using a fuse puller or needle-nose pliers. Start the engine and let it run until it stalls, which indicates that the fuel pressure has been relieved. Crank the engine for an additional 2-3 seconds to bleed off any remaining pressure, then turn the ignition OFF. Reinstall the fuse or relay after you complete the pump replacement work .

Step 2: Disconnect the Battery – Use a 10mm socket to remove the negative battery terminal and isolate it so it cannot spring back into contact with the battery post. This prevents any accidental electrical shorts or sparks during the repair.

Step 3: Access the Fuel Pump Service Cover – Move the second-row seat(s) as needed to access the carpet area above the fuel tank. Remove any trim fasteners using a trim clip remover tool, then carefully peel back the carpet to expose the metal access cover. Remove the screws or bolts securing the access cover using a Phillips screwdriver or 10mm socket, depending on the fastener type used on your model .

Step 4: Clean the Area and Disconnect Electrical Connector – Use shop towels to clean the area around the pump flange thoroughly, preventing dirt and debris from falling into the fuel tank when you open it. Unplug the pump electrical connector by pressing the release tab and pulling it straight off.

Step 5: Disconnect Fuel Lines – Place a drain pan and shop towels under the fuel lines to catch any residual fuel. Use a fuel line disconnect tool set to release the quick-connect fittings .

Step 6: Remove the Pump Assembly – Use a fuel pump lock ring wrench or a brass punch and dead-blow hammer to rotate the lock ring counterclockwise. Lift the pump assembly straight out of the tank. Be careful not to bend the fuel level sending unit arm.

Step 7: Install the New Pump – Transfer any components that are not included with the new pump assembly, such as the fuel level sender or the rubber grommet. Install the new pump assembly into the tank, making sure the alignment tab fits into the slot. Install the lock ring and tighten it clockwise using the lock ring wrench.

Step 8: Reconnect Everything – Reconnect the fuel lines and electrical connector. Install the access cover and tighten the screws. Reconnect the negative battery terminal. Turn the ignition to the ON position and check for fuel leaks before starting the engine.
