Problems starting the engine Nissan Qashqai are often associated with a faulty fuel system, and one of the first things to check is fuel pump fuse. This small but critical element protects the pump's electrical circuit from overloads and short circuits. If it burns out, fuel stops flowing to the engine, and the car either does not start at all or stalls a few seconds after starting.

In this article we will look at where the fuel pump fuse is located on Qashqai first (J10, 2006–2013) and second (J11, 2013–2021) generations, how to check and replace it, as well as what signs indicate its failure. We will pay special attention differences in fuse location on petrol and diesel versions, as this often becomes a source of confusion among owners.

Where is the fuel pump fuse located? Nissan Qashqai?

Depending on generation and engine type Qashqai The fuel pump fuse may be located in different blocks. Below is a table with the exact location for all modifications:

Generation Engine type Fuse box Fuse number Denomination (A)
J10 (2006–2013) Gasoline (1.6, 2.0) In the cabin (under the steering wheel) F30 15
J10 (2006–2013) Diesel (1.5 dCi, 2.0 dCi) Under the hood (main unit) F10 20
J11 (2013–2021) Petrol (1.2 DIG-T, 1.6, 2.0) Inside (left panel) F27 15
J11 (2013–2021) Diesel (1.6 dCi) Under the hood (secondary unit) F15 20

On petrol Qashqai J10 the fuse is located in interior under the steering column. To get to it, open the fuse box cover (it is secured with latches) and find the element marked F30. On diesel versions of this generation, the fuse is located in engine compartment block, which is located next to the battery.

U Qashqai J11 The situation is similar, but the fuse numbers are different. Gasoline models have F27 in the cabin unit, and diesel ones - F15 under the hood. Please note that on some restyled versions (2017+) location may vary slightly, so always check with electrical circuit your modification.

Signs of a faulty fuel pump fuse

A blown fuse manifests itself with clear symptoms that are difficult to confuse with other faults. Here are the main signs:

  • 🚗 The engine does not start, but the starter turns. At the same time, there is no characteristic buzzing sound fuel pump when the ignition is turned on.
  • ⚡ The car starts, but immediately stalls after 2-3 seconds (the fuel from the ramp is exhausted, but the pump does not supply new fuel).
  • ⚠️ The dashboard lights up Check Engineand the scanner shows an error P0190 (fuel pressure sensor circuit malfunction).
  • ⛽ When you try to start the engine, you hear relay clicks, but the pump does not turn on.

If you experience any of these symptoms, the first thing to do is check the fuse. However, do not rush to change it: sometimes the problem lies in fuel pump relay (it is located next to the fuse) or in the pump itself. To rule out other problems, perform simple diagnostics:

  1. Turn the key to position ON (do not start the engine).
  2. Listen: if the pump is working properly, you will hear a slight whirring sound from under the rear seat (on gasoline models) or from the side of the fuel tank (on diesel).
  3. If there is no sound, check the fuse and relay.
💡

On diesel Qashqai The high pressure fuel pump (HPFP) may make noise even if the main pump fuse is faulty. To accurately diagnose the problem, use a multimeter to check the voltage at the pump connector.

How to check the fuel pump fuse?

Checking the fuse takes no more than 5 minutes and does not require special tools. You will need:

  • 🔧 Flat screwdriver (to open the block).
  • 🔍 Flashlight (to better see the markings).
  • 📊 Multimeter (optional, to check voltage).

Algorithm of actions:

Find the fuse box (see table above)|

Open the unit cover by pressing the latches|

Find fuse by number (F30, F27, etc.)|

Visually inspect the fuse for broken thread|

If necessary, check the voltage at the contacts (should be 12V when the ignition is on) -->

If the fuse externally intact, but problems with starting remain, check it with a multimeter:

  1. Set the test mode chains (dialing).
  2. Touch the fuse terminals with the probes. If it is working, the device will show 0 ohm (or beeps).
  3. When broken, the resistance will tend to infinity.

Also make sure that there is voltage present at the fuse contacts. 12V with the ignition on. If there is no voltage, the problem may be fuel pump relay or in the wiring.

How to check the fuel pump relay?

The relay is located next to the fuse (usually marked K20 or K27). To check it:

1. Remove the relay and inspect the contacts for oxidation.

2. Swap with a known good relay (such as a fan relay).

3. If the pump starts working after replacement, the relay is faulty and requires replacement.

Step-by-step instructions for replacing the fuse

If the fuse is blown, it must be replaced with a new one same denomination. Using a fuse with a different amperage may result in a fire or failure of the fuel pump!

Replacement instructions:

  1. Turn off the ignition and remove the key from the lock.
  2. Open the fuse box cover (in the passenger compartment or under the hood, depending on the model).
  3. Find the fuse by number (see table above) and remove it using plastic tweezers (usually included with the block).
  4. Install a new fuse same denomination (15A or 20A).
  5. Close the block cover and try to start the car.

If the fuse blows again after replacement, this indicates short circuit in the fuel pump circuit. In this case it is necessary:

  • 🔧 Check the wiring from the fuse box to the pump for damage.
  • 🛠️ Inspect the fuel pump connector (contacts often oxidize or burn).
  • 🚘 Diagnose the pump itself - perhaps it consumes increased current due to wear.
💡

If the fuse blows repeatedly, it is strictly forbidden to install a “bug” (a wire jumper). This may cause the wiring to catch fire!

Common mistakes when diagnosing and replacing

Many owners Qashqai make typical mistakes that complicate troubleshooting. Here are the most common of them:

  • 🔍 Confusing the fuel pump fuse with the fan fuse. On J10 they are located nearby (F30 And F31), but have different denominations.
  • ⚡ They don't check the relay. Even if the fuse is intact, a faulty relay may block power supply to the pump.
  • 🛠️ Using a fuse of the wrong rating. For example, they put 20A instead of 15A, which leads to overheating of the circuit.
  • 🚗 Ignores checking the fuel filter. A clogged filter increases the load on the pump, which can cause the fuse to blow.

Another common mistake is incorrect diagnosis by sound. For example, on diesel Qashqai When you turn on the ignition, you can hear the operation of the fuel injection pump, but the main fuel pump (in the tank) is silent. This is misleading, forcing you to look for the problem in the wrong place.

⚠️ Attention: On petrol Qashqai J11 with engine 1.2 DIG-T fuel pump fuse (F27) is often confused with the injection system fuse (F28). They are located nearby, but have different purposes. Before replacing, make sure you are working with the correct element!

Prevention and care tips

To avoid problems with the fuel pump fuse, follow these recommendations:

  • 🔧 Check regularly contact status in the fuse block. Oxidation or weakening of contacts can lead to overheating and burnout.
  • ⛽ Follow cleanliness of the fuel tank. Dirt and rust in the tank will accelerate wear on the pump, increasing stress on the chain.
  • 🚗 At the first signs of unstable pump operation (jerking at high speeds, long startup) check the voltage on its connector.
  • 🛠️ Use only original fuses or high-quality analogues (for example, Littlefuse or Bussmann). Cheap Chinese fuses may have inaccurate ratings.

It is also worth paying attention to fuel pump relay. Over time, its contacts burn out, which leads to unstable operation of the pump. If you notice that the car has become harder to start in wet weather, most likely the problem is in the relay - moisture accelerates the oxidation of the contacts.

On diesel Qashqai pay extra attention fuel lines. Air leaks in the system can lead to increased load on the pump and, as a result, to a blown fuse. Regularly check the tightness of connections and the condition of the fuel lines.

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

Is it possible to drive with a blown fuel pump fuse?

No. If the fuse is blown, the fuel pump does not work and fuel does not flow to the engine. The car either won’t start or stalls a few seconds after starting (due to remaining fuel in the ramp). Movement in this state is impossible.

Why does the fuel pump fuse blow again after replacement?

This indicates short circuit in a circuit or increased load to the pump. The reasons may be as follows:

  • The insulation of the wiring from the fuse box to the pump is damaged.
  • The fuel pump itself is faulty (for example, the rotor is jammed).
  • Short circuit in the pump connector (oxidation, moisture ingress).

In this case it is required circuit diagnostics multimeter or contact service.

Where to buy a fuse for a fuel pump Qashqai?
