Fuel pump relay Nissan Qashqai J10: where is it located and how to check?

Owners Nissan Qashqai first generation (J10, 2007–2013) often encounter the problem of the fuel pump suddenly turning off. The cause may be a faulty **fuel pump relay** - a small but critical element that is responsible for supplying voltage to the pump. If the engine does not start, but the starter turns, the first thing to check is this relay.

In this article you will find exact location of the fuel pump relay on Qashqai J10 with a photo of the fuse box, connection diagram and step-by-step instructions for diagnostics. We will also look at typical symptoms of a malfunction, ways to check the relay without special tools, and the nuances of replacement. The information is relevant for petrol versions with engines HR16DE, MR20DE and diesel K9K (although the scheme may differ for diesel engines).

Where is the fuel pump relay located on the Nissan Qashqai J10?

On Nissan Qashqai J10 The fuel pump relay is located in fuse and relay box in the passenger compartment, which is located to the left of the steering column, under the instrument panel. To access it:

1. Open the driver's door and sit down to see under the steering wheel.
2. Remove decorative cover fuse box - it is attached to two latches (pull it towards you).
3. On the back of the cover you will find a diagram of the location of the relays and fuses.

Fuel pump relay Qashqai J10 denoted as Fuel Pump Relay and is marked R17 (in some versions - R27, depends on the year of manufacture). It is located in top row of the block, closer to the center (see photo below).

Important: for diesel versions Qashqai J10 (engine K9K) the fuel pump relay may be located in a different location - in the block under the hood (near the battery). If your car is diesel, check the location using the VIN or manual.

Fuel pump relay connection diagram

Fuel pump relay Qashqai J10 It works according to the classical scheme: when the ignition is turned on, it closes the circuit, supplying voltage to the pump. Below is a simplified connection diagram:

Relay contact	Purpose	Wire color
85	Control signal from the ECU	Black and white
86	Ground (closed via ECU)	Brown
87	Output to fuel pump (+12V)	Pink-black
30	Constant plus from the battery	Red

If the relay fails, the circuit opens and the pump stops receiving power. Often the problem is accompanied absence of the characteristic hum of the pump when the ignition is turned on (normally it is heard for 2–3 seconds).

How to test a circuit without a multimeter?

If you don't have a tester, you can temporarily short-circuit pins 30 and 87 on the relay with a piece of wire. If after this the pump starts working, the problem is definitely in the relay. But do not leave such a “crutch” circuit for too long: it may burn the fuse or the pump itself.

Symptoms of a faulty fuel pump relay

Before you mess with the relay, make sure that it is the problem. Typical symptoms of a malfunction:

• 🔴 The engine does not start, although the starter turns (no fuel supply).
• 🔴 When you turn on the ignition, you can’t hear the fuel pump running (no buzzing from under the rear seat).
• 🔴 The car stalls while driving, then starts only after several attempts.
• 🔴 Lights up on the dashboard Check Engine (the error may indicate an open circuit in the pump).
• 🔴 The fuel pump works constantly (does not turn off after starting the engine) - a sign of a “stuck” relay.

Important! Similar symptoms can cause:

• 🔋 Discharged battery (voltage below 11.5V).
• 🛢️ Clogged fuel filter or pump screen.
• 🔌 Blown fuel pump fuse (usually F27, 15A).
• 🚗 Malfunction of the pump itself (wear of brushes, jamming of the rotor).

How to check the fuel pump relay on Qashqai J10?

Checking the relay takes 5–10 minutes and does not require special skills. You will need multimeter or at least a control lamp (12V). Follow the instructions:

If the relay does not click when voltage is applied or the winding resistance is zero/infinity, it is faulty. Also note blackening or melting of contacts - this is a sign of overheating.

Alternative way to check (without instruments):

1. Remove the fuel pump relay and replace it with a known good one (for example, a cooling fan relay, if similar).
2. Try starting the car. If the engine starts, the problem is in the relay.

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

If the relay is faulty, it must be replaced. The procedure is simple:

1. Disconnect the negative terminal of the battery (key 10).
2. Remove the fuse box cover under the steering wheel.
3. Find the relay R17 (or R27) and carefully remove it by pulling it up.
4. Install a new relay (original part number - 25230-JM00A or analogues TYCO V23134-A1003-A01, MEAT & DORIA 9861533500).
5. Connect the battery and check the pump operation.

The cost of the original relay is about 800–1200 rubles, analogues are 300–600 rubles. When purchasing, pay attention to rated current (must be at least 30A) and compatible with Nissan.

⚠️ Attention! Do not install relays with a lower current rating (for example, 20A instead of 30A) - this may result in melted contacts or a fire in the fuse box.

Common mistakes when diagnosing a fuel pump

Many car owners make common mistakes that complicate the search for the problem:

• 🔧 Only check the relay, ignoring the fuse F27 (15A), which often burns out during power surges.
• 🔧 They don’t take into account that on diesel Qashqai J10 The pump relay may be located in another unit (under the hood).
• 🔧 They confuse the fuel pump relay with the ECU main relay (R18), which also affects startup.
• 🔧 They do not check the voltage at the pump connector (it should be 12V when the ignition is turned on).

Another common mistake is replacing a relay without checking the circuit. For example, if the problem is oxidized fuse box contacts or a broken wire, the new relay will quickly fail.

⚠️ Attention! If after replacing the relay the fuel pump still does not work, check body weight near the fuel tank. On Qashqai J10 it often oxidizes, which leads to chain breakage.

FAQ: Frequently asked questions about the Qashqai J10 fuel pump relay

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

No. If the relay does not operate, the fuel pump will not receive power and the engine will not start. In rare cases (for example, when a relay is “stuck”), the pump may run continuously, which will lead to its overheating and failure.

Which fuse controls the fuel pump on the Qashqai J10?

The fuel pump fuse is designated as F27 (15A) and is located in the same block as the relay. If the fuse blows, the pump will not receive power, even if the relay is working properly.

What is the difference between the fuel pump relay on gasoline and diesel Qashqai J10?

On petrol versions, the relay controls the voltage to the fuel pump in the tank. On diesel (K9K) it may be responsible for fuel heating or shut-off valve, and the relay itself is often located in a block under the hood.

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

The relay is a non-repairable element. In rare cases, it is possible to clean oxidized contacts, but this is a temporary solution. If the winding breaks or the contacts burn, replacement is required.

Where to buy an original relay for Qashqai J10?

Original relay (25230-JM00A) can be ordered from official dealers Nissan or in trusted online stores (for example, Exist.ru, Autodoc). Analogues from TYCO or MEAT & DORIA cheaper, but not always reliable.
