2017 Honda Accord Fuel Pump: Symptoms, Replacement Guide, and the Best Upgrade for Your Car
If you own a 2017 Honda Accord and your car is showing signs of a failing fuel pump — such as hard starting, sputtering at highway speeds, stalling, or a whining noise from the rear of the vehicle — the fuel pump is likely the culprit. Replacing it promptly is essential to avoid being stranded and to prevent potential engine damage. The 2017 Honda Accord can use either a genuine OEM fuel pump (which can cost over $400 from the dealer) or a high-performance aftermarket replacement like KEMSO, which offers OEM-level quality, more flow, and a lifetime warranty at a fraction of the price.
Understanding the 2017 Honda Accord Fuel Pump
The fuel pump in your 2017 Honda Accord is an in-tank electric pump that delivers fuel from the tank to the engine at a precise pressure. For the 2.4L four-cylinder engine, the OEM part number is 17045-T2A-L02, which replaces older numbers 17045-T2A-L00 and 17045-T2A-L01 . This assembly includes the pump, filter, sending unit, and pressure regulator all in one module . The 2017 Accord Hybrid uses a different pump, part number 17045-T3Z-A31 .
The importance of a properly functioning fuel pump cannot be overstated. It must maintain the correct fuel pressure — typically between 43 and 68 psi for most EFI systems — to ensure the engine runs smoothly, accelerates properly, and starts reliably. When the pump begins to fail, every aspect of your driving experience suffers.
7 Clear Signs Your 2017 Honda Accord Needs a New Fuel Pump
Recognizing the symptoms of a failing fuel pump early can save you from a breakdown on the highway. Here are the most common warning signs :
1. Hard Starting or Extended Cranking
The most noticeable symptom is when your Accord takes longer than usual to start. You may need to crank the engine for several seconds before it fires up. This happens because the pump is not building enough pressure in the fuel lines quickly.
2. Sputtering or Hesitation at High Speeds
If your car sputters, hesitates, or loses power when you accelerate, especially at highway speeds, the fuel pump is likely struggling to deliver enough fuel to meet the engine's demand. This is a classic sign of a pump that is on its way out.
3. Stalling While Driving
A failing fuel pump can cause the engine to stall unexpectedly, particularly when you are driving at low speeds or idling. This is dangerous because you can lose power steering and brake assist.
4. Whining Noise from the Fuel Tank
A healthy fuel pump makes a quiet, steady hum. If you hear a loud whining or howling sound coming from the rear of the car, especially near the fuel tank, the pump bearings are worn out and the pump is about to fail.
5. Loss of Power Under Load
When you try to climb a hill or accelerate quickly, the engine may feel weak or sluggish. The pump cannot supply enough fuel pressure to maintain performance.
6. Check Engine Light Illuminates
Your Accord's computer monitors fuel pressure and air-fuel ratio. If the pump is failing, the check engine light will likely come on. Common diagnostic trouble codes include P0087 (Fuel Rail Pressure Too Low) or P0171 (System Too Lean).
7. Engine Surges or Bucks
If the fuel pump delivers inconsistent pressure, the engine may surge or buck while cruising at a steady speed. This feels like the car is jerking forward and back without any change in throttle input.
Diagnosing the Fuel Pump Problem
Before buying a replacement pump, you should confirm the diagnosis. The most reliable method is a fuel pressure test . You will need a fuel pressure gauge that connects to the service port on the fuel rail. For a 2017 Accord, the fuel pressure at idle should be within the manufacturer's specification. If the pressure is low or drops quickly after the engine is turned off, the pump is failing.
Note: A failing fuel pump can also cause damage to the fuel injectors or the engine if the fuel mixture becomes too lean. Do not drive the car for extended periods with a confirmed bad pump.
OEM vs. Aftermarket Fuel Pump: Which One Should You Choose?
When replacing the fuel pump in your 2017 Accord, you have two main options: a genuine OEM Honda pump or an aftermarket replacement.
OEM Honda Fuel Pump
The genuine Honda pump for the 2.4L Accord is part number 17045-T2A-L02 . The MSRP is around $617, but you can find it online for about $437 . For the Accord Hybrid, part 17045-T3Z-A31 costs around $483 . These pumps come with a 12-month manufacturer warranty and are guaranteed to fit perfectly . The downside is the high cost, especially if you are paying for labor at a dealership.
Aftermarket Performance Fuel Pumps (Like KEMSO)
Aftermarket pumps like KEMSO offer a compelling alternative. They are designed as direct OEM replacements, meaning they bolt in without any modifications to wiring, brackets, or fuel lines . Compared to a stock OEM pump, a KEMSO pump delivers over 20% more flow at 43 psi, making it a high-performance upgrade even for a daily driver . The pump body diameter is typically 3.8 cm, and it operates at 43-68 psi, matching the stock system requirements . KEMSO pumps are tested individually at the factory and come with a lifetime warranty .
Why Choose KEMSO for Your 2017 Honda Accord?
KEMSO fuel pumps are built as high-performance, OEM replacement units. They are designed to meet or exceed factory specifications for fuel pressure, flow rate, and electrical characteristics. This means you get the same performance as a $400 dealer pump for a fraction of the price. Every KEMSO fuel pump comes with a lifetime warranty that covers defects in materials and workmanship for as long as you own the pump. If it ever fails due to a manufacturing defect, KEMSO replaces it for free .
Many cheap aftermarket pumps fail within six months to a year because they use lower quality materials and less precise manufacturing. KEMSO pumps are different. They are individually tested before leaving the factory to ensure they meet performance standards. The quality control program follows ISO/TSO standards .
How to Replace the Fuel Pump on a 2017 Honda Accord
Replacing the fuel pump on a 2017 Accord is a job that many DIYers can tackle with the right tools. The fuel pump is accessed from inside the vehicle, under the rear seat. Here is a general overview of the steps:
1. Relieve Fuel System Pressure
Locate the fuel pump fuse in the fuse box and remove it. Start the engine and let it run until it stalls. This relieves pressure in the fuel lines.
2. Disconnect the Battery
Disconnect the negative battery terminal to prevent any electrical shorts or sparks.
3. Access the Pump
The fuel pump module is located under the rear seat on the driver's side. Remove the rear seat cushion by pulling up on the front edge. You will see a metal access cover. Remove the screws or bolts holding the cover.
4. Disconnect the Hoses and Wiring
Carefully disconnect the fuel lines. There are quick-connect fittings that require a special tool to release. Also, unplug the electrical connector for the pump.
5. Remove the Old Pump
Use a special spanner wrench or a hammer and drift to loosen the locking ring that holds the pump module in the tank. Turn the ring counterclockwise and lift the pump assembly out of the tank. Be careful not to damage the fuel level float.
6. Install the New Pump
Transfer the rubber gasket and any other components from the old assembly to the new KEMSO pump. The KEMSO kit includes a gradient density fuel strainer, flex hose, tank seal, Viton o-rings, wiring connectors, and zip-ties . Install the new pump assembly into the tank, making sure the float is oriented correctly. Tighten the locking ring clockwise.
7. Reconnect Everything
Reconnect the fuel lines and electrical connector. Install the access cover and reinstall the rear seat. Reconnect the battery and the fuel pump fuse.
8. Test the System
Turn the ignition key to the "ON" position (without starting the engine) three times, waiting 2 seconds each time, to prime the fuel system. Check for leaks around the connections. Then start the engine and let it idle. Check for leaks again.
Preventing Future Fuel Pump Problems
Once you replace the fuel pump, follow these simple rules to make it last as long as possible :
1. Keep Your Tank Above a Quarter Full
This is the single most important thing you can do. It keeps the pump submerged in fuel, which cools and lubricates it. In hot weather, heat is the number one enemy of fuel pumps.
2. Change Your Fuel Filter Regularly
For most vehicles, the recommended interval is every 30,000 to 60,000 miles. A clean fuel filter reduces strain on the pump and protects it from debris.
3. Use Quality Fuel from Reputable Stations
Avoid stations that look old and poorly maintained. Busy stations with high turnover are less likely to have old or contaminated fuel.
4. Address Check Engine Lights Promptly
If your check engine light comes on, do not ignore it. The computer may have detected a fuel pressure issue that you cannot feel yet.
5. Listen to Your Vehicle
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.
