Nissan Qashqai is one of the most popular crossovers in Russia, but even it is not immune to problems with the fuel system. The fuel pump relay, despite its simple design, often causes sudden engine stops or difficulty starting. In this article we will look at how to independently diagnose a malfunction, where to look for a relay in Qashqai J10 (2007–2013) and J11 (2014–2021), as well as the nuances of replacement without contacting service.

The peculiarity of the problem is that the symptoms of a non-working relay can easily be confused with a breakdown of the fuel pump itself or the fuse. For example, if when you turn the ignition key you do not hear the characteristic buzzing of the pump in the tank, the culprit may be something like fuse F30 (15A), so fuel pump relay (usually marked K27 or K28). We will analyze in detail how to distinguish one from the other and save on diagnostics.

Where is the fuel pump relay located? Nissan Qashqai?

Depending on the crossover generation, the relay location may differ. B Qashqai J10 (Dorestayl and Restayl) the fuse and relay box is located under the hood, next to the battery. The relay you are looking for is usually installed in main block (black plastic box with a lid) and is marked Fuel Pump Relay or K27.

B Qashqai J11 (2014–2021) the manufacturer moved part of the relay inside the cabin - under glove compartment, behind the plastic panel. To get to it you will have to:

  • 🔧 Open the glove compartment and take out all the contents.
  • 🔧 Press the panel fasteners at the bottom of the glove compartment and carefully remove it.
  • 🔧 Find the relay block (usually gray) and look for the inscription Fuel Pump or K28.
📊 Where is your fuel pump relay located?
  • Under the hood
  • Under the glove compartment
  • I don't know, I haven't looked yet
  • I have a different model

Important: on some versions Qashqai with engines HR16DE And MR20DD the relay can be duplicated - one under the hood, the other in the cabin. This is done for circuit redundancy. If you're not sure, check wiring diagram for your year of manufacture.

Signs of a faulty fuel pump relay

The fuel pump relay rarely fails suddenly - it is usually preceded by “symptoms” that drivers often ignore. Here are the key signs:

  • 🚗 Engine won't start or it starts only after several attempts (while the starter turns).
  • ⚡ Lights up on the dashboard Check Engineand the scanner shows an error P0190 (fuel pressure sensor circuit malfunction).
  • 🔊 When you turn the key to position ON I can't hear the fuel pump running (no characteristic buzzing from the tank).
  • ⛽ Engine stalls while driving, especially during sudden acceleration or at high speeds.

Please note: if the pump buzzes, but the engine does not start, the problem is most likely in the pump itself or clogged fuel filter. If there is no buzzing at all, the relay, fuse or wiring is to blame.

💡

Before replacing the relay, check the fuse F30 (15A) in the block under the hood. It is responsible for the fuel pump circuit and often burns out during power surges.

How to check the fuel pump relay with a multimeter?

To diagnose the relay you will need multimeter (or even a simple 12V light bulb). Follow the instructions:

  1. Remove the relay from the block (remember its location or take a photo).
  2. Check winding resistance:
    • Connect the multimeter probes to the terminals 85 And 86 (control contacts).
    • Resistance must be within 50–120 Ohm. If the device shows OL (break) or 0 (short circuit) - the relay is faulty.
  3. Check the functionality of the contacts:
    • Connect 12V to conclusions 85 And 86 (polarity is not important).
    • Using a multimeter in continuity mode, check the short circuit between 30 And 87. When voltage is applied, a beep should sound.

If the relay does not click when voltage is applied or the contacts do not close, it needs to be replaced. Also inspect soldering contacts on the relay board: often oxidation or cold soldering causes a malfunction.

Fuel pump relay connection diagram Nissan Qashqai

To understand how a circuit works, consider a typical circuit for Qashqai J11 with engine MR20DD:

Relay contact Purpose Where does the wire go?
85 Control minus Engine ECU (pin E10)
86 Manager Plus fuse F30 (15A) → ignition switch
30 Constant plus fuse F31 (15A) → battery
87 Pump output Fuel pump (connector on tank)

If upon inspection it turns out that 85 the contact does not receive a control signal from the ECU, the problem may be wiring or the control unit itself. In this case, diagnostics will be required ECU.

What to do if the relay is OK, but the pump does not work?

If the relay clicks but the pump does not start, check:

1. **Fuse F30/F31** - often blows during a short circuit.

2. **Pump weight** - on Qashqai it is attached under the rear seat (bolt on the body).

3. **Wiring from the relay to the pump** - frayed wires or oxidized contacts in the tank connector.

4. **The pump itself** - if 12V comes to its connector, but it does not buzz, most likely the motor winding has burned out.

Replacing the fuel pump relay: step-by-step instructions

If diagnostics confirm a relay malfunction, you can replace it in 5–10 minutes. You will need:

  • 🔧 New relay (original Nissan 25230-JM00A or analogues: Hella 4RA 003 567-331, Bosch 0 332 019 150).
  • 🔧 Flat screwdriver (for removing the block cover).
  • 🔧 Flashlight (if the unit is in the cabin).

Sequence of actions:

  1. Disable negative battery terminal (required!).
  2. Remove the relay block cover (on J10 - under the hood, on J11 - under the glove compartment).
  3. Find the relay marked Fuel Pump and carefully remove it by pulling it up.
  4. Install a new relay same markings (do not confuse with the fan or starter relay!).
  5. Check the operation: turn on the ignition - you should hear the relay click and the pump hum.
💡

Never install relays from other circuits (for example, a fan or headlights) - they have a different response time and current load. This can lead to overheating of the contacts or failure of the ECU.

If after replacing the relay the pump still does not work, check:

  • 🔌 Fuses F30 and F31 - they can burn out if there is a short circuit.
  • 🔌 Contacts in the fuel pump connector (under the rear seat) - often oxidize or come off.
  • 🔌 Pump weight - on Qashqai it is attached to the body under the rear passenger seat.

Cost of relays and replacement analogues

Original relay from Nissan (article 25230-JM00A) costs about 1,200–1,500 rubles. However, you can save money by purchasing analogues from trusted brands:

Manufacturer Article Price, rub. Notes
Hella 4RA 003 567-331 800–1 000 High quality build, suitable for Qashqai J10/J11
Bosch 0 332 019 150 900–1 100 Universal, but check compatibility by contacts
Meat & Doria 98-011 400–600 Budget option, but lower resource
Era 550367 500–700 Suitable for most Nissan/Renault

Important: on Qashqai with engines M9R (diesel) a different type of relay is used - 25230-4M20A. It is not interchangeable with petrol versions!

When purchasing an analogue, pay attention to:

  • 🔍 Rated current - must be no less 30A.
  • 🔍 Contact type — the original uses gold-plated contacts for better conductivity.
  • 🔍 Dimensions — some Chinese analogues have a different case size.

Common mistakes when replacing a fuel pump relay

Even experienced car owners sometimes make mistakes that lead to repeated breakdowns. That's what can't do:

⚠️ Attention: Never check the serviceability of the relay “for spark” by connecting it directly to the battery without load. This may burn contacts or cause a short circuit in the on-board network.

Other common mistakes:

  • 🚫 Relay installation from another circuit (for example, from a fan or headlights). This will lead to overheating of the contacts, since the current loads are different.
  • 🚫 Ignoring verification fuses F30/F31. If they burn out, the new relay will also quickly fail.
  • 🚫 Replacement of relay only without testing pump weight. On Qashqai it often oxidizes, which leads to repeated failures.
  • 🚫 Buying cheap analogues without gold-plated contacts. They oxidize quickly, especially in high humidity conditions.

If the problem remains after replacing the relay, do not rush to change the fuel pump. First check:

  • 🔧 Pump connector voltage (must be 12V with the ignition on).
  • 🔧 Signal from ECU to contact 85 relay (should appear when you turn the key).
  • 🔧 Wiring integrity from the relay to the tank (often frays under the threshold).

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

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

No. If the relay does not work, the fuel pump does not pump fuel and the engine won't start. In rare cases, the car may start “on the remaining pressure” in the ramp, but will travel no more than 100–200 meters.

Why does the relay click but the pump does not work?

This means that the relay is working properly, but the problem is:

  • Burnt out fuse F30/F31;
  • Precipice wires from relay to pump;
  • Malfunctions the fuel pump itself (the winding burned out or the rotor jammed);
  • Bad pump weight (oxidation or wire break).
What relay can be installed instead of the original one?

Analogues from Hella (4RA 003 567-331), Bosch (0 332 019 150) or Era (550367). The main thing is that the relay is 4-pin with markings 30–85–86–87 and rated current not less than 30A.

Where to buy a fuel pump relay for Nissan Qashqai?

The original relay can be ordered from official dealers Nissan or in online stores (for example, Exist.ru, Autodoc). Analogues are sold in auto parts stores (Hella, Bosch) or on AliExpress (but be careful with the quality).

Can the fuel pump relay cause an error? Check Engine?

Yes, if the relay is faulty, the ECU can record errors P0190 (fuel pressure sensor circuit) or P0627 (fuel pump relay circuit malfunction). After replacing the relay, errors must be reset using a scanner or by disconnecting the battery.
