<em>Nissan Note</em>fuel pump relay: diagnostics, malfunctions and do-it-yourself replacement

Nissan Note — a compact and reliable car, but even it is not immune to problems with the fuel system. One of the weak points of the model (especially the first generations E11 and restyled versions) is fuel pump relay. Its failure can lead to a sudden stop of the engine, difficult starting or a complete lack of fuel supply. In this article we will look at how to independently diagnose a malfunction, where the relay is located in Nissan Note, and how to replace it without contacting service.

It is important to understand that problems with the fuel pump are often confused with problems with the pump itself, the fuel filter or the wiring. However, in 60% of cases, the relay is to blame - a small but critical element that controls power to the pump. If your Note stalls while driving, has trouble starting when hot, or makes strange sounds from the gas tank - first check the relay.

We have collected all the relevant information: from relay locations in the fuse box to step-by-step replacement instructions with photos and videos. You will also find out what original relay part numbers are suitable for different years of manufacture Nissan Note (2006–2013 and 2013–2020), and how to distinguish a fake from a quality spare part.

Where is the fuel pump relay located? Nissan Note?

In most versions Nissan Note (including E11 And E12) the fuel pump relay is located in fuse and relay box under the hood. The exact location depends on the year of manufacture:

• 🔧 2006–2013 — fuse box to the right of the battery (under the plastic cover). The fuel pump relay is usually second from the right in the top row (slot number - R17 or R18, depending on the configuration).
• 🔧 2013–2020 — the unit has been moved closer to the windshield, next to the ECU mounting block. The fuel pump relay is labeled here as Fuel Pump Relay and has a number R30.
• 🔧 Diesel versions (For example, Note 1.5 dCi) - the relay may be located in the interior fuse box (under the steering wheel, to the left of the pedals).

To avoid confusion, focus on diagram on the block cover - All relays and fuses are listed there with captions. If there is no diagram (for example, after replacing the cover), use a multimeter to check (more on this below).

⚠️ Attention: On some versions Nissan Note with the system Keyless Go The fuel pump relay is integrated into the immobilizer control unit. In this case, replacing the relay separately is impossible - diagnostics of the entire module is required.

If you are unsure of the location, use service manual for your modification. For example, for Note E11 with engine HR15DE The fuse box diagram differs from the version with K9K (diesel).

Signs of a faulty fuel pump relay

Fuel pump relay Nissan Note may fail gradually or suddenly. Let's consider main symptoms, which indicate its malfunction:

• 🚗 Engine won't start, but the starter turns. At the same time, there is no characteristic buzzing of the fuel pump when the ignition is turned on.
• ⚡ The car stalls while driving and does not start until the relay cools down (typical for “tired” contacts).
• ⛽ Jerks when moving, especially at high speeds - a sign of intermittent fuel supply.
• 🔥 Smell of burnt plastic from under the hood (the relay overheats due to oxidized contacts).
• 🔊 Clicking sounds from the fuse box when you turn the key, the relay tries to operate, but the contacts do not close.

It is important to distinguish a relay malfunction from problems with the fuel pump itself. For example, if the pump hums but doesn't pump fuel, most likely it is himself or a clogged filter that is to blame. What if there is not even a sound of the pump running - first check the relay and fuse.

Symptom	Probable Cause	Action
No sound from fuel pump when ignition is turned on	Faulty relay or fuse	Check relay R17/R30 and fuse F15 (15A)
The car starts only after several attempts	Relay contacts burnt out	Replace the relay, check the pump connector
The engine stalls while driving, then starts	Relay overheating or contact oxidation	Check the voltage at the relay with the engine running
Jerks during acceleration	Unstable pump power	Diagnose relays and wiring with a multimeter

If you observe several symptoms at the same time (for example, the car does not start well and stalls while driving), the problem may be complex: relay + pump + filter. In this case, start with the simplest thing - checking the relay.

How to check the fuel pump relay with a multimeter?

Diagnostics of the fuel pump relay in Nissan Note does not require special skills. You will need multimeter (or a simple test lamp) and a screwdriver. Follow the step by step instructions:

1. Remove the relay from the fuse block. In its place there should be a diagram indicating the contacts (usually 85, 86, 87, 30).
2. Ring the winding: connect the multimeter probes to the contacts 85 And 86. Resistance must be within 50–120 Ohm. If the device shows a break, the relay is faulty.
3. Check your contacts: serve 12V on 85 And 86 (for example, from a battery). There should be a click and the contacts 30 And 87 close up. Check this with a multimeter in dial mode.
4. Diagnose the connector: If the relay is OK, check the voltage at the fuse box connector (contact 85 must show 12V with the ignition on).

If the relay does not click when voltage is applied or the contacts do not close, it needs to be replaced. Also inspect fuse box connector for oxidation or burning of contacts. Often the problem lies there.

⚠️ Attention: Do not test the fuel pump relay for a spark - this may damage the electronic components. Nissan Note. Use only a multimeter or a test lamp with a limiting resistor.

If you don't have a multimeter, you can temporarily install known good relay (for example, from a cooling fan - they are often interchangeable). If the fuel pump works after replacement, the problem is confirmed.

Articles and analogs of fuel pump relay for Nissan Note

When replacing the fuel pump relay, it is important to select quality spare part. Original relays from Nissan reliable, but often counterfeited. Below is a table with articles for different generations Note:

Model and year	Original article	Analogs (brand + article)	Notes
Nissan Note E11 (2006–2013)	25230-JM00A	Bosch 0 332 019 150, Hella 4RA 003 507-121	Suitable for petrol versions with HR15DE
Nissan Note E12 (2013–2020)	25230-JM01A	Valeo 405031, Febi 35610	For diesel versions - 25230-JM02A
Note with Keyless Go	25230-4M20A (as part of the module)	Only original	Separate replacement is not possible

When purchasing analogues, pay attention to rated current - it must be no less 30A. Cheap relays of unknown brands (for example, NoName from China) often cannot withstand the load and burn after 1–2 months.

Where to buy:

• 🛒 Official dealers Nissan - guarantee of the original, but the price is 30–50% higher.
• 🛒 Specialty stores (For example, Exist.ru, Autodoc) - there are proven analogues.
• 🛒 Used markets - only if the relay was removed from a similar model and tested.

⚠️ Attention: Relay from Nissan Micra K13 And Juke F15 they are similar in appearance, but have a different response time characteristic. Their installation can lead to unstable operation of the fuel pump.

How to distinguish an original relay from a fake?

Original relay Nissan has:

1. Clear marking of the article and logo Nissan on the body (not a sticker!).

2. The case is made of heat-resistant plastic (does not smell like cheap plastic).

3. Contacts made of copper with a silver coating (counterfeits have coated steel).

4. Weight ~30 grams (counterfeits are 5–10 grams lighter).

5. Packaging - branded package Nissan with a hologram.

Step-by-step instructions for replacing the fuel pump relay

Replacing the relay in Nissan Note takes no more than 10 minutes and does not require special tools. You will need:

• 🔧 Flat screwdriver (for removing the block cover).
• 🔧 Tweezers or pliers (for removing the relay).
• 🔧 New relay (see article number above).
• 🔧 Multimeter (optional, for checking).

Procedure:

1. Disconnect the battery (remove the negative terminal) - this is mandatory for safety.
2. Remove the fuse box cover under the hood. On Note E11 it is fixed with two latches, on E12 - four.
3. Find the fuel pump relay (see section above about location). Carefully remove it with tweezers by pulling up.
4. Install a new relay to the same nest. Make sure it is seated all the way.
5. Check your work: Connect the battery, turn on the ignition (you should hear the sound of the fuel pump) and start the engine.

If after replacing the relay the car does not start:

• 🔋 Check the fuse F15 (it could burn out due to a short circuit).
• 🔌 Inspect the fuel pump connector under the rear seat - the contact may have come loose.
• 🛠️ Check the wiring from the relay to the pump (there should be 12V on the pump connector with the ignition on).

If you replaced the relay, but the problem remains, the reasons may be deeper:

• 🔧 Faulty itself fuel pump (brush wear, rotor jamming).
• 🔧 Crowded fuel filter (especially relevant for diesel engines) Note).
• 🔧 Problems with Engine ECU (for example, error P0190 — malfunction of the fuel pressure sensor circuit).

💡

If after replacing the relay the fuel pump does not turn on, the first thing to check is the fuse F15 and voltage at the pump connector (should be 12V when the ignition is on).

Common mistakes when replacing relays and how to avoid them

Even something as simple as replacing a relay can lead to new problems if mistakes are made. Let's consider typical mistakes and ways to prevent them:

• 🔌 Installing a relay from another model. For example, a relay from Nissan Almera N16 looks similar, but has a different time delay. This leads to unstable pump operation and jerks when moving.
• 🔧 Ignoring oxidized contacts. If the fuse box connector is oxidized, the new relay will quickly fail. Clean your contacts alcohol solution or a special liquid (for example, Kontakt 60).
• ⚡ Replacing a relay without checking the fuse. If the fuse F15 burned out, the new relay will not work. Always check the entire chain.
• 🛠️ Use of force when installing the relay. If the relay does not engage easily, check to see if the legs are bent. Strong pressure can damage the unit connector.

Another common mistake is buying a relay without checking the article number. For example, for Note E11 with engine HR16DE suitable relay 25230-JM00A, and for E12 with the same engine - already 25230-JM01A. Specify the article number for your modification!

If after replacing the relay the car starts, but after some time the problem returns, the reasons may be as follows:

• 🔥 Short circuit in the circuit (check the wiring from the relay to the pump for chafing).
• 💧 Moisture entering the fuse box (relevant after washing the engine).
• 🔋 Immobilizer malfunction (on some versions it blocks power to the pump).

💡

After replacing the fuel pump relay, reset the ECU errors (if any). To do this, disconnect the battery for 10 minutes or use a diagnostic scanner (for example, ELM327).

Prevention: how to extend the life of the fuel pump relay?

Fuel pump relay Nissan Note is not an eternal element, but its resource can be significantly increased by following simple recommendations:

• 🔋 Check your battery regularly. low voltage in the on-board network (less than 11.5V) leads to an increase in current through the relay and its overheating.
• ⛽ Monitor your fuel level. Driving "on a light bulb" overloads the fuel pump, which indirectly affects the relay.
• 🚿 Avoid pressure washing the engine. Moisture that gets into the fuse box causes corrosion of the contacts.
• 🔌 Clean your contacts periodically fuse box (every 2–3 years). Use WD-40 or Liqui Moly Kontakt-Spray.
• 🔧 Check the fuse F15 at every maintenance. Its burnout is the first signal of problems in the circuit.

If you frequently drive off-road or in high humidity conditions, it is recommended seal the fuse box. To do this, use silicone sealant or special covers (for example, from 3M).

It is also worth paying attention to fuel quality. Poor gasoline with impurities accelerates wear on the fuel pump, which increases the load on the relay. Refuel at reputable gas stations and use additives to clean the fuel system (for example, Liqui Moly Fuel System Cleaner).

⚠️ Attention: If you are installing additional equipment (such as a subwoofer or winch), make sure that it is connected through a separate relay and fuse. Overloading the on-board network can damage the fuel pump relay.

FAQ: Frequently asked questions about the fuel pump relay Nissan Note

Is it possible to drive with a faulty fuel pump relay?

No, it's dangerous. If the relay does not work, the fuel pump will not pump fuel and the engine will stall. In some cases (for example, with burnt contacts), the car may start, but stall while driving, which creates an emergency situation. At the first sign of malfunction, the relay must be replaced.

How much does a fuel pump relay cost? Nissan Note?

The price depends on the type of relay and place of purchase:

• Original relay (25230-JM00A) - from 800 to 1500 rubles.
• Analogues (Bosch, Hella) - from 400 to 800 rubles.
• Used relay - from 200 to 500 rubles (risk of buying a faulty one).

Buy only from trusted stores to avoid counterfeits.

How to test a relay without a multimeter?

If you don't have a multimeter, you can use control lamp or replace the relay with a known good one (for example, from a radiator fan). Also note clicks when you turn on the ignition - if they are not there, the relay is faulty.

What should I do if the fuel pump does not work after replacing the relay?

Check the following:

1. fuse F15 (15A) - it could burn out.
2. The voltage at the fuel pump connector (should be 12V with the ignition on).
3. Condition of the ground wire of the pump (often oxidizes under the rear seat).
4. The fuel pump itself may have failed.

If the problem persists, contact an auto electrician to diagnose the wiring.

Can the fuel pump relay be repaired or is it just a replacement?

The fuel pump relay is a non-repairable element. In rare cases, you can clean the contacts, but this is a temporary solution. If the winding or contacts burn out, the relay must only be replaced. Attempts to “restore” it often lead to a short circuit and failure of the ECU.
