2006 Altima Fuel Pump: Complete Guide to Replacement, Cost, and Best Options

If you own a 2006 Nissan Altima and your engine cranks but won’t start, or you’re experiencing poor acceleration and sputtering, the fuel pump is often the culprit. The bottom line is this: replacing the fuel pump on a 2006 Nissan Altima typically costs between $250 and $900 total installed, depending on whether you choose aftermarket or OEM parts and where you get the work done. For a 2006 Altima, the pump is an electric in-tank unit that delivers fuel from the tank to the engine under the correct pressure. This guide walks you through everything you need to know—symptoms, cost breakdown, replacement steps, and the best fuel pump options available.

Signs Your 2006 Nissan Altima Fuel Pump Is Failing

Before you start shopping for a replacement, it helps to confirm that the fuel pump is actually the problem. Here are the most common symptoms:

  1. Engine cranks but won’t start – This is the classic sign. If you hear the starter turning but the engine never fires, the fuel pump may not be delivering fuel.
  2. Sputtering at high speeds – A failing pump can’t maintain consistent pressure, causing the engine to hesitate or surge while driving.
  3. Loss of power under load – When you accelerate uphill or merge onto the highway, the engine may feel sluggish.
  4. Whining noise from the fuel tank – A healthy fuel pump makes a quiet hum. A loud whining or buzzing sound means the pump is wearing out.
  5. Difficulty starting after the car sits – If the pump is leaking pressure internally, the fuel system loses prime, making it harder to start.

Keep in mind that electrical issues like a blown fuse or a bad relay can mimic a failed fuel pump. Always check the fuses and relays first before replacing the pump.

2006 Nissan Altima Fuel Pump Options: What Fits Your Car

The 2006 Nissan Altima came with two engine options: a 2.5L four-cylinder (QR25DE) and a 3.5L V6 (VQ35DE). The fuel pump assembly is the same for both engines in most cases, but there is one important exception: California emissions vehicles use a different pump. For non-California emissions models, the pump has a two-port fuel line connector on top. If your Altima is a California emissions vehicle, the pump has a single-port connector.

Here are the most common replacement options:

OEM (Genuine Nissan) Fuel Pump

  • Part Number: 17040-7Y000 (replaced by 17040-ZD80B)
  • Fits: 2003-2006 Altima (2.5L and 3.5L), 2004-2006 Maxima, 2004-2006 Quest
  • Price: Typically $150 to $350 for the part alone
  • Pros: Guaranteed fitment, factory warranty, exact OEM specifications
  • Cons: Higher cost than aftermarket options

Aftermarket Fuel Pump Assembly

  • Common Interchange Numbers: E8545M, 67991 (Bosch), P76169M (Carter), A6247M (DriveBolt)
  • Fits: 2004-2006 Nissan Altima 2.5L and 3.5L (non-California emissions), 2004-2008 Maxima 3.5L, 2004-2009 Quest 3.5L
  • Price: Typically $50 to $120 for the part
  • Pros: Lower cost, widely available, many include the sending unit and float
  • Cons: Quality varies by brand; may not last as long as OEM

If you choose an aftermarket pump, make sure it comes as a complete module assembly. Most aftermarket units include the fuel pump, fuel pressure regulator, sending unit, float, fuel reservoir, strainer, and tank seal. That saves you from having to buy those parts separately.

To avoid surprises, always ask for a written estimate that lists parts, labor, taxes, and any additional fees separately.

How to Replace the Fuel Pump on a 2006 Nissan Altima

Replacing the fuel pump is a job you can do yourself if you have basic mechanical skills and the right tools. Be aware that this is not a quick job—it involves working around the fuel tank, which is heavy and contains flammable fuel. Here is a step-by-step outline of the process:

Step 1: Safety First

  • Disconnect the negative battery cable.
  • Work in a well-ventilated area away from open flames or sparks.
  • Have a fire extinguisher nearby.

Step 2: Relieve Fuel System Pressure

  • Remove the fuel pump relay from the fuse box.
  • Start the engine and let it run until it stalls. This burns off the fuel pressure in the lines.
  • Try to start the car a couple more times to make sure all pressure is gone.

Step 3: Access the Fuel Pump

  • The fuel pump is located inside the fuel tank. On the 2006 Altima, you typically access it by removing the rear seat cushion and then removing the access cover on the floor pan.
  • If your model requires dropping the tank, you will need to safely lift the rear of the vehicle with a jack and jack stands, then disconnect the fuel filler neck, fuel lines, and electrical connectors before lowering the tank.

Step 4: Remove the Old Fuel Pump Assembly

  • Disconnect the electrical connector from the top of the pump module.
  • Use a fuel line disconnect tool to release the quick-connect fittings on the fuel lines.
  • Remove the retaining lock ring using a special lock ring tool or a screwdriver and hammer.
  • Carefully lift the fuel pump assembly out of the tank. Be prepared for some residual fuel to spill.

Step 5: Install the New Fuel Pump

  • Compare the new pump assembly with the old one to make sure they match.
  • Replace the rubber seal (O-ring) on the tank opening. Clean the sealing surface thoroughly.
  • Lower the new pump assembly into the tank, making sure it sits in the correct orientation.
  • Reinstall the lock ring and tighten it securely.

Step 6: Reassemble and Test

  • Reconnect the fuel lines and electrical connector.
  • Raise the fuel tank back into position (if you dropped it) and reconnect all lines and connectors.
  • Reconnect the battery and reinstall the fuel pump relay.
  • Turn the ignition key to the ON position (without starting the engine) and listen for the fuel pump to prime. You should hear a quiet humming sound.
  • Check for any fuel leaks around the tank and fuel lines.
  • Start the engine and let it run for a few minutes to confirm everything is working properly.

Pro Tips to Extend the Life of Your New Fuel Pump

Once you install a new fuel pump, you want it to last as long as possible. Here are three simple habits that can help:

  1. Keep your fuel tank above 1/4 full. The fuel in the tank helps cool the electric pump. Running consistently low can cause the pump to overheat and fail prematurely.
  2. Use high-quality fuel. Clean fuel prevents deposits from building up inside the pump and clogging the fuel filter.
  3. Replace the fuel filter regularly. A clogged fuel filter puts extra strain on the pump, shortening its lifespan. Check your owner’s manual for the recommended replacement interval.
