2000 Infiniti I30 Fuel Pump: Complete Guide to Symptoms, Replacement, and Cost

If you own a 2000 Infiniti I30 and suspect your fuel pump is failing, the bottom line is this: a failing fuel pump will cause hard starts, stalling, and loss of power, and replacing it yourself can save you hundreds of dollars. The 2000 Infiniti I30 uses an in-tank electric fuel pump, and the OEM part numbers are 17042-2Y900 and 17042-2Y904 . Depending on the brand you choose, a replacement fuel pump will cost between $44 and $369 for the part alone, and a professional replacement typically runs between $498 and $662 including labor . This guide will walk you through everything you need to know about the 2000 Infiniti I30 fuel pump, from symptoms to replacement options, so you can make an informed decision and get your car back on the road.

How the Fuel Pump Works in Your 2000 Infiniti I30

The fuel pump in your 2000 Infiniti I30 is an electric, in-tank unit that sits inside the fuel tank . Its job is to deliver pressurized fuel from the tank to the fuel injectors, which then spray fuel into the engine. The pump is controlled by the Engine Control Module (ECM), which activates the fuel pump relay. When you turn the ignition key to the ON position, the ECM runs the fuel pump for about one second to prime the system. Once the engine starts and the ECM detects the engine is rotating, the pump continues to run. If the engine stops, the ECM shuts off the pump within 1.5 seconds for safety . The fuel pump relay is a key component in this system, so if your pump won't run, the relay should be checked first. The fuel pump operates at a pressure of around 3.4 to 3.8 bar (about 49 to 55 psi) .

Common Symptoms of a Failing Fuel Pump in a 2000 Infiniti I30

Recognizing the signs of a bad fuel pump early can save you from being stranded. Here are the most common symptoms:

  1. Engine struggles to start or cranks longer than normal. A failing pump can't build enough fuel pressure, so the engine may crank for several seconds before firing up, or it may not start at all .
  2. Loss of power under acceleration or uphill. When you press the gas pedal, the engine needs more fuel. A weak pump can't supply that extra fuel, causing hesitation, stumbling, or a complete lack of power .
  3. Engine stalling, especially at idle. A failing pump may not provide consistent fuel flow, causing the engine to stall when you're stopped at a light or driving slowly .
  4. Whining noise from the fuel tank area. A healthy fuel pump makes a quiet hum. If you hear a loud, high-pitched whine or a buzzing sound coming from the back of the car near the fuel tank, the pump is likely wearing out .
  5. Decreased fuel efficiency. If you notice you're filling up more often than usual, a failing pump might be delivering fuel at the wrong pressure, forcing the engine to run inefficiently .
  6. Check engine light. If the ECM detects a problem with the fuel system, such as low fuel pressure, it will turn on the check engine light. Common codes include P0087 (Fuel Rail/System Pressure - Too Low) .

Genuine OEM vs. Aftermarket Fuel Pump Options for the 2000 Infiniti I30

When it's time to replace the fuel pump, you have several choices. The right one depends on your budget and how long you plan to keep the car.

1. Genuine Infiniti (OEM) Fuel Pump

The factory original part is the safest choice. It is guaranteed to fit perfectly and meet the exact performance specifications of your I30. The OEM part numbers for the 2000 I30 are:

  • 17042-2Y900: This is the full in-tank fuel pump assembly. It lists for around $505.72, but you can find it online for about $368.67 .
  • 17042-2Y904: This is a different version of the in-tank fuel pump assembly. It is slightly smaller and lighter than the 2Y900, and also fits the 2000 I30 Base and T/Pack models .
    Both are direct replacements and come with a manufacturer's warranty . Buyers looking for a 100% guarantee of fitment and quality should choose genuine Infiniti parts.

2. Aftermarket Fuel Pump Options

Aftermarket pumps can save you a significant amount of money. Many are built to OE specifications and are trusted by mechanics.

  • Delphi: Priced around $143.87, Delphi is a well-known OEM supplier. The part for the 2000 I30 is an in-tank electric fuel pump. Delphi recommends cleaning the fuel tank before installing a new pump to prevent contamination .
  • Hitachi: Hitachi is an actual OE supplier for many Japanese vehicles. Their in-tank fuel pump for the 2000-2001 Infiniti I30 and Nissan Maxima costs about $143.87. It is a pump-only unit, meaning you will need to reuse your existing mounting bracket and strainer .
  • TRQ: A very budget-friendly option, the TRQ FPA62101 fuel pump costs about $44.95. It is an internal pump with a maximum flow rating of 47.55 GPH and a maximum pressure of 125 PSI. It comes with a limited lifetime warranty, but note that parts with electrical components cannot be returned once installed .
  • GMB: GMB offers an electric in-tank fuel pump for the 2000 I30. It is sold individually and built to OE specs, but it does not include a gasket, wiring harness, or mounting bracket .
  • Walbro: Walbro is a performance brand that also makes OEM replacement pumps. A Walbro fuel pump kit for the 1996-1999 Infiniti I30 is available for about $175.94, but it is not clear if it directly fits the 2000 model year, so you should check fitment .

DIY Replacement Cost and Difficulty for the 2000 Infiniti I30 Fuel Pump

If you are handy with tools, replacing the fuel pump on a 2000 Infiniti I30 is a job you can do yourself. It is considered a medium-difficulty task and should take between 1 and 3 hours .

What you will need:

  • Basic hand tools (sockets, wrenches, screwdrivers)
  • A new fuel pump assembly
  • A new fuel filter (highly recommended to replace at the same time)
  • A fuel tank cleaning kit (recommended by Delphi to prevent contamination)
  • Safety glasses and gloves

Estimated Costs:

  • DIY Parts Cost: $50 to $300. This range covers the cheapest aftermarket pump (like the $45 TRQ unit) to the genuine Infiniti assembly .
  • Professional Repair Cost: $498 to $662. This includes the cost of the part plus labor .
  • DIY Savings: You can save between $100 and $400 by doing the job yourself .

Important Safety Precautions

Working on a fuel system is dangerous. Fuel is highly flammable, and the system is under pressure. Before you start:

  1. Disconnect the battery. This prevents any sparks from electrical components .
  2. Relieve the fuel system pressure. The 2000 Infiniti I30 has a fuel pressure regulator on the fuel rail; you can relieve pressure by pulling the fuel pump relay and running the engine until it stalls.
  3. Work in a well-ventilated area. Gasoline fumes are toxic.
  4. Keep a fire extinguisher nearby.
  5. If you smell fuel, burning insulation, or see smoke, stop immediately and contact a professional mechanic .

Step-by-Step Replacement Overview

This is a simplified overview. Always consult a factory service manual for your specific vehicle before starting.

  1. Access the Fuel Pump: The fuel pump is located under the rear seat. You will need to remove the rear seat cushion.
  2. Remove the Access Panel: Under the seat, you will find a metal access cover. Remove the screws and lift the cover.
  3. Disconnect Electrical Connectors and Fuel Lines: Carefully disconnect the wiring harness and the fuel supply and return lines. Be prepared for some fuel spillage.
  4. Remove the Locking Ring: Use a hammer and a blunt punch or a specialized tool to turn the large locking ring counterclockwise.
  5. Lift Out the Old Assembly: Carefully lift the entire fuel pump and sending unit assembly out of the tank. Note the orientation of the float arm.
  6. Install the New Assembly: Transfer any necessary components (like the rubber grommet or fuel strainer) to the new pump assembly if you are using a pump-only unit. Place the new assembly into the tank, ensuring the float arm is positioned correctly.
  7. Replace the Locking Ring: Install the locking ring and turn it clockwise until it is tight.
  8. Reconnect Everything: Reconnect the fuel lines and electrical connectors. Make sure they are secure.
  9. Prime the System: Turn the ignition key to the ON position for 2 seconds, then OFF. Repeat this 3-4 times to prime the fuel system without starting the engine.
  10. Check for Leaks: Start the engine and inspect all connections for fuel leaks. Reinstall the access cover and rear seat.

Additional Tips for a Successful Replacement

  • Replace the fuel filter: Always replace the fuel filter when you install a new fuel pump. A clogged filter can cause the new pump to fail prematurely .
  • Clean the fuel tank: Fuel tank contamination is the leading cause of premature fuel pump failure. If you see any debris or rust in the tank, clean it out using a fuel tank cleaning kit .
  • Use a quality part: While the $45 TRQ pump is tempting, a more expensive aftermarket pump from Delphi or KEMSO will likely last longer and provide more consistent performance.
  • Check the fuel pump relay: If your new pump doesn't work, the problem might be a bad relay, not the pump itself. The relay is located in the fuse box and is a common failure point .

Frequently Asked Questions

How long does a 2000 Infiniti I30 fuel pump last?
Factory fuel pumps typically last between 150,000 and 200,000 kilometers (about 93,000 to 124,000 miles). This can vary depending on fuel quality and driving habits .

Can I drive with a bad fuel pump?
You should not drive with a failing fuel pump. It can cause the engine to stall at any time, which is very dangerous, especially at highway speeds. It can also damage other fuel system components, such as the fuel injectors .

Is the fuel pump the same for the 2000 Infiniti I30 and the 2000 Nissan Maxima?
Yes, the 2000 Infiniti I30 and the 2000 Nissan Maxima share the same platform and engine (the VQ30DE). Many aftermarket fuel pumps, such as those from Hitachi and GMB, are listed for both vehicles .

Final Recommendation

The 2000 Infiniti I30 is a reliable car, but its fuel pump will eventually wear out. When it does, you have a clear choice. If you want a perfect fit and are willing to spend more, the genuine Infiniti fuel pump (17042-2Y900 or 17042-2Y904) is the best option. If you want to save money, the KEMSO fuel pump is an excellent high-performance alternative that comes with a lifetime warranty. For a budget-friendly DIY fix, the TRQ pump is a very low-cost option, but its long-term reliability is unproven. Regardless of which option you choose, a prompt replacement will restore your car's performance and keep you safely on the road.
