Replacing the fuel pump on a Nissan Note: a complete guide with photos and videos

Fuel pump in Nissan Note - a critical component of the fuel system, on which stable engine operation depends. Its failure may manifest itself as jerks during acceleration, difficult starting, or a complete stop of the engine. Unlike many foreign cars, where replacement requires complex dismantling, in Note (especially models E11 And E12) the procedure is relatively accessible even for beginners with minimal tools.

This article will help you figure out when replacement (and not cleaning or repair) is really needed, how to choose a quality pump among analogues Hitachi, Denso or Bosch, and carry out the work without errors. We will analyze in detail the process of removing the rear seat, disconnecting the fuel lines and dismantling the module, and also give advice on bypassing the typical problem with tank mounts “souring” on cars older than 2012. If you have never worked with the fuel system, don’t worry: step by step, even difficult moments will become clear.

Signs of a faulty fuel pump in a Nissan Note

The first symptoms of problems with the fuel pump are often attributed to low-quality fuel or clogged injectors. However there is characteristic features, which directly indicate wear or breakdown of the pump:

• 🔴 Engine starts only after prolonged rotation of the starter (3-5 seconds or more) - the pump does not create the required pressure when first turned on.
• 🚗 Jerks when moving at a constant speed (especially noticeable on the highway at 90-110 km/h) - fuel is supplied unevenly.
• ⚡ Power Loss when accelerating sharply, it’s as if the car is “choking” - the pump does not have time to supply enough gasoline.
• 🛑 The engine stalls while driving, and restarting is possible only after the pump has cooled down (typical for winding overheating).
• 🔊 Hum or whistle from under the rear seat when the ignition is turned on - a sign of wear on the bearings or impeller.

On Nissan Note with engines HR15DE (1.5 l) and HR16DE (1.6 L) most common premature wear of electric motor brushes pump due to poor fuel quality. In models after 2015, the problem occurs less frequently due to the modified module design, but is not completely excluded. If you observe at least 2-3 symptoms from the list, it’s time to check the pressure in the fuel rail.

⚠️ Attention: On cars with a mileage of more than 150 thousand km, a whistling sound from the pump when starting up may be normal due to natural wear and tear. But if the sound becomes louder or vibration appears, this is a direct signal for replacement.

How to check the fuel pump before replacing

Before you spend money on a new pump, make sure that this is the problem. For diagnostics on Nissan Note A multimeter and a pressure gauge (or even a simple “hearing” test) are enough. Here is a step-by-step algorithm:

1. Voltage check:
   • Remove the rear seat and open the gas filler flap.
   • Disconnect the pump power connector (gray or black plastic block).
   • Turn on the ignition (without starting the engine) and measure the voltage at the connector contacts. Must be 12 V.
2. Pressure check:
   • Connect the pressure gauge to the fuel rail fitting (on the engine, under the hood).
   • When the ignition is turned on, the pressure should jump to 3-4 bar and hold for 5+ seconds.
   • If the pressure drops below 2.5 bar or the pump does not turn on at all - it is faulty.
3. Listening test:
   • When you turn on the ignition (without starting the engine), listen for a sound coming from under the rear seat.
   • A working pump emits a steady hum for 2-3 seconds. Lack of sound or grinding noise is a sign of a breakdown.

If the pump does not turn on at all, check fuse (usually F30 (15A) in the block under the steering wheel) and relay (located in the same place, marking R17). On models Note E12 (2012-2016) oxidation of relay contacts is common - they can be cleaned with alcohol.

Symptom	Probable Cause	Action
The pump does not hum when the ignition is turned on	Defective relay, fuse or open circuit	Ring the circuit, check the relay/fuse
Pressure below 2.5 bar	Worn impeller or clogged screen	Replacing the pump or cleaning the mesh
The pump works, but the engine stalls	Fuel level sensor or check valve is faulty	Diagnostics of the module assembly
The hum of the pump became louder	Worn bearings or impeller	Replacing the pump soon

Choosing a fuel pump for Nissan Note: original vs analogues

There are more than 20 options for fuel pumps on the market. Nissan Note, but not all of them are reliable. Original pump from Nissan (article 17040-JM00A or 17040-JM00B for models after 2013) will cost 8 000–12 000 ₽, but its resource rarely exceeds 150 thousand km. Alternatives from trusted brands can last longer at a lower cost.

Here best analogues, confirmed by owner reviews:

• 🔹 Hitachi P700-1002 — direct analogue of the original, resource 200+ thousand km, price ~5 500 ₽.
• 🔹 Denso 953-0101 - high performance, but can be noisy, price ~6 200 ₽.
• 🔹 Bosch 0 580 454 035 - universal option, suitable for Note E11/E12, price ~4 800 ₽.
• 🔹 AIRTEX E2319M — budget option (~3 500 ₽), but the resource is lower (up to 100 thousand km).

When choosing, pay attention to complete set: Ideally, the pump should come with a new filter screen, O-ring and mounting bolts. If you buy a used module, check the condition of the fuel level sensor float (on Note it often breaks).

⚠️ Attention: There are many fake brands on the market Hitachi And Denso. The original pumps have a laser engraved logo on the body and come in branded packaging with a hologram. Check with the seller for certificates!

How to spot a fake fuel pump?

Counterfeit pumps often have:

- Uneven seams on the plastic body.

- Blurred or pasted label (there is a clear print on the original).

- Lack of protective cover on the power connector.

- Weight is 100-150 grams less (fakes use thinner metal).

Preparing for replacement: tools and safety precautions

Replacing the fuel pump with Nissan Note does not require a pit or a lift, but will require caution due to working with fuel. Here full list of tools:

Phillips screwdriver (PH2)

10 mm socket with extension

Pliers

Hammer (for carefully removing stuck flange)

New fuel pump with o-ring

Rags and rubber gloves

Fire extinguisher (required!)

Container for draining gasoline (5-10 liters)

-->

Before starting work necessarily:

1. Disconnect the negative terminal of the battery.
2. Drain the gasoline tank to a level below the pump (or use a hand pump to drain).
3. Work in a well-ventilated area or outdoors (gasoline vapors are explosive!).
4. Do not smoke or use open flames near the machine.

On models Note E11 (2006-2012) there is often a problem with sticking of the fuel pump flange to the tank. To remove it without damage, you can:

• Treat the joint with WD-40 and wait 10-15 minutes.
• Gently tap the flange through the wooden spacer with a hammer.
• Use a special puller (sold in auto tools).

Step-by-step instructions for replacing the fuel pump

Replacement process Nissan Note takes 1.5–2 hours the first time you try. Follow the instructions strictly step by step to avoid mistakes:

1. Removing the rear seat:

   Use a screwdriver to pry up the plastic plugs for the seat fastenings (there are 2–4 of them depending on the year of manufacture) and unscrew the bolts with a 10 mm socket. Lift the seat up and it will release from the latches.

2. Access to the fuel pump hatch:

   Under the seat you will see a square hatch (15x15 cm) with a rubber seal. Carefully cut the sealant with a knife or bend the edge with a screwdriver. Be careful - there may be gasoline under the hatch!

3. Disconnecting fuel lines:

   Press the plastic tube clamps (green or black clips) and pull the hoses off. Place the container - gasoline may spill out! Use a cloth to cover the holes in the tubes to prevent dirt from entering.

4. Removing the electrical connector:

   Press the metal latch on the power connector and disconnect it. Check the contacts for oxidation and clean them with alcohol if necessary.

5. Removing the fuel pump:

   Unscrew the 8 flange mounting bolts (10 mm head). If the flange cannot be removed, use the methods in the previous section. Carefully remove the pump module by tilting it so as not to damage the fuel level sensor float.

6. Installing a new pump:

   Compare the new pump with the old one - all connectors and tubes should match. Install a new O-ring onto the flange. Lower the module into the tank, aligning the grooves, and secure with bolts (tighten crosswise!).

7. Connection and testing:

   Connect the tubes and power connector. Turn on the ignition for 5 seconds (the pump should hum) and check the tightness of the connections. Start the engine and let it idle for 2-3 minutes.

If after replacement the engine does not start or runs intermittently, check:

• Pump connection polarity (plus and minus reversed?).
• Tightness of fuel pipes (no air leaks?).
• Rail pressure (should be 3-4 bar).

Typical replacement mistakes and how to avoid them

Even experienced car owners sometimes make mistakes that lead to repeated disassembly or even damage to the car. Here the most common mistakes and how to prevent them:

• 🔧 Incorrect flange tightening:

  If you overtighten the bolts, you can deform the tank or break the threads. Tighten crosswise firmly 5–7 Nm (no more!).

• ⚡ Mixed up fuel pipes:

  On Note The fuel supply pipe (from the pump to the ramp) is usually marked with a green clip, and the return pipe is marked with a black clip. If you mix it up, the engine won't start.

• 🔥 Ignoring tank cleaning:

  If there is dirt or rust in the tank, it will quickly clog the new pump. Before installation, vacuum the tank or wash it with a special liquid.

• 🛠️ Damage to the level sensor float:

  When removing the module, it is easy to break the plastic float. If this happens, replace the level sensor (part no. 28501-JM00A).

• 🔋 Poor polarity:

  If you confuse “+” and “-” on the pump connector, it will burn out immediately when turned on. On original pumps, the plus is usually indicated by a red wire.

Another typical problem is fuel leak after replacement. Most often it occurs due to:

• Damaged O-ring (always install a new one!).
• Insufficient tightening of the tubes (check the clip clamps).
• Cracks in the plastic fittings of the module (inspect them before installation).

⚠️ Attention: If after replacement the pump works, but the engine stalls after 5-10 minutes, check check valve in the module. On cheap analogues it often does not hold pressure. The solution is to replace the module assembly.

How much does it cost to replace a fuel pump at a service center?

If you are not confident in your abilities, you can entrust the replacement to professionals. The cost of work in services varies depending on the region and level of the service station:

Service type	Cost of work (₽)	Lead time	What's included
Official dealer Nissan	4 000–6 000	2–3 hours	Diagnostics, replacement, pressure check
Specialized car service	2 500–4 000	1.5–2 hours	Replacing the pump, cleaning the tank (optional)
Garage workshops	1 500–2 500	1–1.5 hours	Replacement only, no warranty
Mobile auto electrician	3 000–4 500	2–3 hours	Departure, replacement, diagnostics

Is it worth overpaying for official service? Only if your car is under warranty. In other cases, it is better to choose a proven car service with good reviews. Please note that many service stations charge an additional fee (~500–1 000 ₽) for:

• Draining fuel from the tank.
• Cleaning the fuel system.
• ECU diagnostics after replacement.

Replacing it yourself will only cost the cost of the pump (3 500–12 000 ₽), but will require time and accuracy. If you do not have experience, it is better not to take risks - mistakes when working with the fuel system can result in expensive repairs.

FAQ: Frequently asked questions about replacing the fuel pump on a Nissan Note

Is it possible to drive with a faulty fuel pump?

Short term - yes, but it is fraught pump overheating (may jam) or damage to injectors due to low pressure. If the pump is already “dying”, it is better not to risk it and replace it as soon as possible. In practice, many people drive with a noisy pump for months, but it’s like playing roulette - it can fail at any time.

How often do you need to change the fuel pump on a Nissan Note?

Service life of the original pump - 120,000–180,000 km. In practice it depends on:

• Fuel quality (impurities reduce the resource by 30-40%).
• Replace the fuel filter regularly (if it is clogged, the pump is overloaded).
• Driving style (frequent trips with an almost empty tank accelerate wear).

If you refuel at trusted gas stations and keep an eye on the filter, the pump can last for a long time. 200,000+ km.

What happens if the flange O-ring is not replaced?

Old rings lose their elasticity and do not seal the connection. This leads to:

• Air leak - the engine will stall or stall.
• Gasoline leaks - fire hazard!
• Flange Corrosion - Over time, the tank may begin to rust.

The seal is worth 100–300 ₽, but replacing it will save you thousands in repairs.

Is it possible to repair the fuel pump instead of replacing it?

In 80% of cases the pump must only be replaced, but sometimes it helps:

• Cleaning the filter mesh (if the pump pumps poorly due to clogging).
• Replacing electric motor brushes (requires a soldering iron and skills).
• Washing the impeller from deposits (effective only with light contamination).

If the pump does not turn on or is noisy, repair is pointless. On Nissan Note It’s cheaper and more reliable to install a new one.

Which fuel pump is better - original or analogue?

Original pump (17040-JM00A/B) is guaranteed to fit the parameters, but its service life is often lower than that of high-quality analogues. Optimal options:

• For durability: Hitachi P700-1002 or Denso 953-0101.
• To save: Bosch 0 580 454 035 (but check the pressure after installation!).
• For the original build: only Nissanif the car is under warranty.

Avoid cheap no-name pumps - they often do not hold pressure and fail after 20,000–30,000 km.
