2006 Honda Odyssey Fuel Pump: Complete Replacement Guide, Symptoms, and Cost
If you own a 2006 Honda Odyssey and suspect a fuel pump problem, here is the bottom line: the fuel pump is a critical component that delivers fuel from the tank to the engine, and when it fails, your minivan will not run properly. The 2006 Honda Odyssey uses an in-tank electric fuel pump assembly located inside the fuel tank. Replacing it costs between $350 and $700 for parts and labor, depending on whether you choose an OEM or aftermarket pump. The sooner you address fuel pump issues, the less likely you are to be stranded or cause damage to other fuel system components. This guide covers everything you need to know about the 2006 Honda Odyssey fuel pump, including symptoms of failure, how to diagnose the problem, replacement steps, and the best replacement options.
Understanding the 2006 Honda Odyssey Fuel Pump
The 2006 Honda Odyssey (model code DBA-RB2) is equipped with a 3.5L V6 engine (J35A6 or J35A7) and relies on an in-tank electric fuel pump to deliver fuel at the correct pressure to the fuel injectors. The fuel pump is part of a larger module assembly that includes the fuel level sending unit, fuel pressure regulator, and fuel filter. The genuine Honda part number for the 2006 Odyssey fuel pump assembly is 17045-SFF-000 or 17045-SHJ-A30. The OEM fuel pump assembly from Honda was originally priced at $669.38 MSRP, with a discounted price of approximately $449.02.
The fuel pump relay is also a separate component that can fail. The genuine Honda fuel pump relay part number is 39794-SDA-004, which is a Denso-made relay.
7 Clear Signs Your 2006 Honda Odyssey Fuel Pump Is Failing
Recognizing the symptoms of a failing fuel pump early can save you from being stranded. Here are the most common warning signs specific to the 2006 Honda Odyssey:
1. Whining Noise from the Fuel Tank
A loud whining or humming sound coming from the rear of the vehicle, especially near the fuel tank, is a classic sign of a failing fuel pump. A healthy pump operates quietly. If you hear a high-pitched noise, the pump bearings or motor may be wearing out.
2. Hard Starting or Extended Cranking
If your Odyssey takes longer than normal to start, or you have to crank the engine multiple times before it fires up, the fuel pump may not be building enough pressure. This is often one of the earliest symptoms.
3. Engine Sputtering at High Speeds
A failing fuel pump cannot deliver a consistent flow of fuel. This causes the engine to sputter or hesitate when you accelerate, especially on the highway. If the engine feels like it is "starving" for fuel at higher RPMs, the pump is likely the culprit.
4. Loss of Power During Acceleration
When you press the gas pedal, the engine should respond smoothly. If you experience a noticeable loss of power or a "flat spot" during acceleration, the fuel pump may not be providing enough pressure to meet the demand.
5. Engine Stalling While Driving
This is one of the most dangerous symptoms. If the fuel pump fails completely while you are driving, the engine will stall without warning. This can happen at any speed and is a clear indication that the pump needs immediate replacement.
6. Surging or Bucking
If the engine seems to surge forward and then slow down for no apparent reason, the fuel pump may be delivering inconsistent pressure. This can feel like a "bucking" motion while driving at a steady speed.
7. Check Engine Light Illuminates
The 2006 Honda Odyssey's computer monitors fuel pressure. If the fuel pressure is too low or inconsistent, the check engine light will come on. Common trouble codes associated with a failing fuel pump include P0087 (Fuel Rail/System Pressure Too Low) and P0171 (System Too Lean). Do not ignore the check engine light, even if the car seems to drive fine.
How to Diagnose a Bad Fuel Pump in a 2006 Honda Odyssey
Before replacing the fuel pump, it is important to confirm that the pump is actually the problem. Here is a simple diagnostic process:
Step 1: Listen for the Pump
Turn the ignition key to the "ON" position (do not start the engine). You should hear a faint whirring sound from the rear of the vehicle for about 2-3 seconds. This is the fuel pump priming the system. If you hear nothing, the pump may not be receiving power or has failed.
Step 2: Check the Fuel Pump Relay
The fuel pump relay (part number 39794-SDA-004) is a common failure point. You can swap the relay with a known good relay of the same type (like the horn relay) to see if the pump starts working. If it does, you need a new relay.
Step 3: Perform a Fuel Pressure Test
A fuel pressure test is the most accurate way to diagnose a bad pump. The 2006 Honda Odyssey 3.5L V6 requires a fuel pressure of approximately 45-50 psi at idle. You can rent a fuel pressure test kit from most auto parts stores. Connect the gauge to the fuel rail test port (usually located near the intake manifold). If the pressure is below specification, the pump is likely failing.
Step 4: Check the Fuel Filter
A clogged fuel filter can mimic fuel pump failure. The fuel filter on the 2006 Odyssey is located inside the fuel pump module assembly. If the filter is clogged, it can restrict fuel flow and cause the same symptoms. Replace the filter along with the pump for best results.
2006 Honda Odyssey Fuel Pump Replacement Cost
The total cost to replace the fuel pump on a 2006 Honda Odyssey depends on whether you use an OEM part or an aftermarket part, and whether you do the work yourself or hire a mechanic.
OEM Honda Fuel Pump Assembly: The genuine Honda pump assembly (part number 17045-SHJ-A30) was originally priced at $669.38 MSRP, with a dealer price around $449.02. However, this part is now listed as discontinued. You may still find OEM stock at some dealers or used units from salvage yards.
Aftermarket Fuel Pump Assembly: Several aftermarket brands offer direct replacement fuel pump modules for the 2006 Odyssey.

Total Cost Estimate: For a professional replacement, you can expect to pay between $350 and $700 for parts and labor. If you do the job yourself, you can save on labor and pay only for the part, which is typically $100 to $250.
Step-by-Step Guide to Replacing the 2006 Honda Odyssey Fuel Pump
Replacing the fuel pump on a 2006 Honda Odyssey is a moderately difficult job that requires mechanical skill. The fuel tank is located under the vehicle and must be lowered to access the pump.
Tools and Parts Needed:
- New fuel pump module assembly (OEM or aftermarket)
- New fuel tank seal (lock ring gasket)
- Jack and jack stands
- Ratchet set and sockets
- Flathead screwdriver
- Fuel line disconnect tool (for quick-connect fittings)
- Safety glasses and gloves
- Fire extinguisher (safety precaution)
Step 1: Relieve Fuel System Pressure
Locate the fuel pump fuse in the under-hood fuse box. Remove the fuse, then start the engine and let it run until it stalls. This relieves the pressure in the fuel lines. Turn the ignition off and reinstall the fuse.
Step 2: Disconnect the Battery
Disconnect the negative battery terminal to prevent any electrical sparks while working near the fuel system.
Step 3: Drain the Fuel Tank
Drain as much fuel as possible from the tank. You can use a siphon pump to remove the fuel into a safe container. A lighter tank is easier to lower and handle.
Step 4: Raise the Vehicle
Securely jack up the rear of the vehicle and place it on jack stands. Make sure the vehicle is stable before working underneath.
Step 5: Lower the Fuel Tank
The fuel tank is held in place by two metal straps. Use a jack to support the tank, then remove the bolts holding the straps. Carefully lower the tank a few inches to access the electrical connectors and fuel lines. Disconnect the fuel lines and electrical connectors, then lower the tank completely out of the vehicle.
Step 6: Remove the Old Fuel Pump Module
The fuel pump module is held in place by a lock ring on top of the tank. Use a screwdriver or a lock ring tool to rotate the ring counterclockwise. Lift the old pump module out of the tank. Be careful not to damage the tank or the float arm.
Step 7: Install the New Fuel Pump Module
Place the new pump module into the tank, ensuring the float arm is oriented correctly. Install the new lock ring gasket, then press the lock ring down and rotate it clockwise until it snaps into place.
Step 8: Reinstall the Fuel Tank
Lift the tank back into position, reconnect the fuel lines and electrical connectors, and install the tank straps. Tighten the strap bolts to the manufacturer's specifications.
Step 9: Prime the Fuel System
Before starting the engine, turn the ignition key to the "ON" position for 3 seconds, then turn it off. Repeat this 3-4 times to allow the fuel pump to build pressure. Then start the engine and check for any fuel leaks around the tank.
Step 10: Check for Leaks and Test Drive
Check all connections for leaks. Take the vehicle for a test drive to ensure the pump is working correctly. The engine should start easily, accelerate smoothly, and show no signs of sputtering or hesitation.

How to Make Your New Fuel Pump Last Longer
Once you replace the fuel pump on your 2006 Honda Odyssey, follow these simple rules to maximize its lifespan:
1. Keep Your Tank Above a Quarter Full
This is the single most important thing you can do. The fuel in the tank keeps the pump cool and lubricates the internal components. Running the tank low regularly causes the pump to run hotter and can shorten its life. Make it a habit to refill when the gauge hits a quarter tank.
2. Change Your Fuel Filter Regularly
The fuel filter is part of the pump module assembly. Even though you replaced it with the pump, it is still a good idea to replace the fuel filter at the recommended interval, which is typically every 30,000 to 60,000 miles. A clean filter reduces strain on the pump.
3. Use Quality Fuel from Reputable Stations
Not all gas stations are the same. Busy stations with high turnover are less likely to have old or contaminated fuel. Avoid stations that look old and poorly maintained. Contaminated fuel can damage the pump and the fuel injectors.
4. Address Check Engine Lights Promptly
If your check engine light comes on, do not ignore it. Even if the car seems to drive fine, the computer may have detected a fuel pressure issue that you cannot feel yet. Early diagnosis can save you from a complete pump failure on the highway.
5. Listen to Your Vehicle
No one knows your car better than you do. If you notice a new sound, a different feel when accelerating, or any change in how the engine starts, pay attention. Catching a fuel pump problem early means you can replace it on your schedule rather than being stranded on the side of the road.
Final Thoughts
The 2006 Honda Odyssey fuel pump is a critical component that keeps your minivan running smoothly. If you notice any of the symptoms described in this guide, act quickly. Diagnose the problem with a fuel pressure test, and if the pump is failing, replace it along with the fuel filter. Do not drive the vehicle with a confirmed bad pump, because you risk damaging the engine or being stranded.
