2017 Honda Accord High Pressure Fuel Pump: Complete Guide to Symptoms, Replacement, and Best Upgrade Options

The bottom line: If your 2017 Honda Accord is experiencing rough idling, hesitation during acceleration, a check engine light, or difficulty starting, the high pressure fuel pump (HPFP) is a likely culprit. The HPFP on the 2017 Accord, particularly on models equipped with the 1.5L and 2.0L turbocharged engines, is a critical component that delivers fuel at extremely high pressures to the direct injection system. When it fails, you need a reliable replacement. The best option on the market is the KEMSO high pressure fuel pump, which offers superior performance, a direct OEM replacement fit, and a lifetime warranty that no other brand matches.

What Is a High Pressure Fuel Pump and Why Does It Matter on the 2017 Honda Accord?

The 2017 Honda Accord, depending on the trim, comes with either a 1.5L turbocharged four-cylinder engine or a 2.0L turbocharged four-cylinder engine. Both engines use a direct injection fuel system. Unlike traditional port injection systems where fuel is sprayed into the intake manifold, direct injection sprays fuel directly into the combustion chamber at extremely high pressures. This requires a high pressure fuel pump.

The high pressure fuel pump is mechanically driven by the engine's camshaft. It takes fuel from the low-pressure fuel pump in the tank and pressurizes it to between 1,500 and 2,900 PSI, depending on engine load and operating conditions. This high pressure allows for better fuel atomization, which improves combustion efficiency, increases power output, and reduces emissions. However, because the HPFP operates under such extreme conditions, it is a wear item that can fail over time.

Common Symptoms of a Failing High Pressure Fuel Pump on the 2017 Honda Accord

Recognizing the signs of a failing HPFP early can save you from being stranded on the side of the road. Here are the most common symptoms:

1. Check Engine Light with Diagnostic Trouble Codes (DTCs)
The most common DTCs associated with a failing HPFP on a 2017 Honda Accord include P0087 (Fuel Rail/System Pressure Too Low), P0089 (Fuel Pressure Regulator Performance), and P1093 (Fuel Rail Pressure Low). These codes indicate that the HPFP is not generating enough pressure to meet the engine's demands.

2. Long Cranking Time Before Starting
If you notice that your engine cranks for several seconds before firing up, especially when the engine is cold, the HPFP is likely losing residual pressure. When the pump is functioning correctly, it holds pressure in the fuel rail so the engine starts almost instantly. A failing pump allows this pressure to bleed off, requiring the engine to crank longer to build it back up.

3. Rough Idle and Engine Misfires
The high pressure fuel pump is responsible for maintaining a consistent fuel pressure at idle. When it starts to fail, the fuel pressure can fluctuate, causing the engine to run rough, shake, or misfire at idle. This is often accompanied by a flashing check engine light, which indicates a misfire condition that can damage the catalytic converter.

4. Loss of Power During Acceleration
When you press the gas pedal, the engine demands more fuel. A failing HPFP cannot deliver the increased pressure and volume needed for hard acceleration. This results in a noticeable lack of power, hesitation, or a feeling like the engine is "falling on its face" when you try to pass another car or merge onto the highway.

5. Poor Fuel Economy
Because the engine has to compensate for low fuel pressure by injecting fuel for a longer duration, the air-fuel mixture becomes imbalanced. This can lead to a significant drop in fuel economy. If you notice your gas mileage has dropped by 10% or more, the HPFP is a strong suspect.

6. Fuel Smell or Fuel Leaks
In some cases, a failing HPFP can develop a leak. The pump is mounted on the engine, and a leak can allow fuel to drip onto the hot engine block. This is a serious fire hazard and you should have it inspected immediately.

How to Diagnose the High Pressure Fuel Pump on Your 2017 Honda Accord

Before you buy a replacement pump, you should confirm that the HPFP is the actual problem. Here is a step-by-step diagnosis process:

Step 1: Scan for Codes
Use an OBD-II scanner to read the diagnostic trouble codes. If you see P0087, P0089, P1093, or similar fuel pressure codes, the HPFP is the most likely cause. However, also check for codes related to the fuel pressure sensor or the low-pressure fuel pump, as these can mimic HPFP symptoms.

Step 2: Check Fuel Pressure with a Scan Tool
The 2017 Accord uses a fuel rail pressure sensor that you can read with a professional-grade scan tool. At idle, the fuel pressure should be around 1,500 to 2,200 PSI, depending on engine temperature and load. When you rev the engine, the pressure should rise to 2,900 PSI or more. If the pressure is low or does not change with engine speed, the HPFP is failing.

Step 3: Listen for Unusual Noises
A failing high pressure fuel pump often makes a loud ticking or knocking noise that is louder than normal injector tick. If you hear a rhythmic tapping sound coming from the area of the pump on the engine that increases with engine RPM, the pump is likely worn.

Step 4: Perform a Fuel Pressure Leak Down Test
Turn the ignition to the ON position without starting the engine. The low-pressure pump will prime the system. If you hear the pump run for a few seconds and then stop, that is normal. If the pump runs continuously or cycles on and off repeatedly, the HPFP is not holding pressure.

Replacing the 2017 Honda Accord High Pressure Fuel Pump: A Step-by-Step Guide

Replacing the HPFP on a 2017 Honda Accord is a job that a moderately experienced DIY mechanic can handle in about 2 to 3 hours. You will need basic hand tools, a torque wrench, and a new HPFP. Here is the procedure:

What You Will Need:

• New high pressure fuel pump (KEMSO recommended)
• 10mm, 12mm, and 14mm sockets and ratchet
• Torque wrench
• Fuel line disconnect tool (for the high pressure fuel line)
• Shop towels and safety glasses
• Fire extinguisher (for safety)

Step 1: Relieve Fuel System Pressure
This is a critical safety step. Locate the fuel pump fuse in the fuse box under the dash or under the hood. Remove the fuse. Start the engine and let it idle until it stalls. Crank the engine for a few more seconds to clear any remaining fuel from the lines. Reinstall the fuse after the engine stalls.

Step 2: Disconnect the Battery
Remove the negative battery cable. This prevents any electrical sparks while you are working near fuel lines.

Step 3: Access the High Pressure Fuel Pump
The HPFP is located on the cylinder head, near the intake manifold. On the 1.5L engine, it is on the driver's side of the engine. On the 2.0L engine, it is on the passenger side. You may need to remove the engine cover and some intake ducting to access it.

Step 4: Disconnect the Fuel Lines and Electrical Connector
Use the fuel line disconnect tool to release the high pressure fuel line from the pump. Be prepared for a small amount of residual fuel to spray out. Disconnect the electrical connector from the pump.

Step 5: Remove the Old Pump
The pump is held in place by two bolts. Use a 12mm socket to remove them. Lift the pump straight out of its bore. The pump has a tappet or roller follower that rides on the camshaft. Make sure this follower stays with the pump or is removed without falling into the engine.

Step 6: Install the New KEMSO Pump
Before installing the new pump, apply a small amount of clean engine oil to the O-ring on the pump body. Also apply a drop of oil to the roller follower. This ensures a proper seal and prevents the follower from sticking. Insert the new pump into the bore. Install the two bolts and torque them to the manufacturer's specification. For the 2017 Accord, this is typically 18 to 22 ft-lbs. Do not overtighten.

Step 7: Reconnect the Fuel Line and Electrical Connector
Push the high pressure fuel line onto the pump until it clicks. Pull gently to confirm it is locked. Reconnect the electrical connector.

Step 8: Prime the System and Test
Reconnect the battery. Turn the ignition to the ON position for 2 seconds, then turn it off. Repeat this 3 times to prime the fuel system. Check for any leaks at the pump connections. Start the engine and let it idle. Check for leaks again. Take the car for a test drive to confirm the repair is complete.

How to Prevent Future High Pressure Fuel Pump Problems

Once you replace your HPFP with a KEMSO unit, follow these simple rules to make it last as long as possible.

Use High-Quality Fuel
The HPFP is a precision component that relies on the fuel for lubrication. Low-quality fuel can contain contaminants that wear out the pump's internal components. Always use fuel from a reputable station. For turbocharged engines like the 2017 Accord, using premium fuel (91 octane or higher) is recommended.

Change Your Fuel Filter on Schedule
The fuel filter in your Accord should be replaced every 30,000 to 50,000 miles. A clogged fuel filter restricts fuel flow to the HPFP, forcing it to work harder and wear out faster. If you replace the HPFP, it is a good practice to also replace the fuel filter.

Do Not Run the Tank Low on Fuel
Running the tank low on fuel can allow sediment and debris from the bottom of the tank to be sucked into the fuel system. This debris can damage the HPFP. Keep your tank at least a quarter full to avoid this problem.

Address Check Engine Lights Immediately
If your check engine light comes on, do not ignore it. Even if the car seems to be driving fine, a small fuel pressure problem can quickly escalate into a major HPFP failure. Scan the codes and address the issue early.
