Fuel pump fuse <em>Nissan Qashqai J10</em>: location, check and replacement

Nissan Qashqai J10 (2007–2013) is one of the most popular crossovers on the Russian market, but even it has weaknesses. One of them is the electrical circuit of the fuel pump, where the fuse plays a key role. If the car suddenly stops starting and the starter turns idle, the culprit may be a blown fuel pump fuse. In this article we will look at where it is located, how to check and replace it, as well as what nuances are important to take into account so as not to burn the new part 5 minutes after installation.

The problem is complicated by the fact that Qashqai J10 The fuel pump fuse may be located in different places depending on the year of manufacture and configuration. In addition, its failure is often disguised as other faults: from immobilizer failure to breakdown of the pump itself. We've collected all the relevant information, including fuse box diagrams, fault symptoms and step-by-step instructions - with photos and explanations for beginners.

Where is the fuel pump fuse located? Nissan Qashqai J10?

B Qashqai J10 The fuel pump fuse can be installed in one of three places. It depends on the modification of the car and the year of manufacture:

• 🔧 Main fuse box in the passenger compartment (under the steering wheel, to the left of the pedals). Look for the fuse F30 (15A) or F32 (10A) - depending on the configuration.
• 🚗 Additional block under the hood (near the battery). Here the fuse can be designated as Fuel Pump or EFI (20A).
• ⚡ Separate fuel pump relay (in some versions it is combined with a fuse and located under the rear seat, next to the pump itself).

The most common mistake is to look for the fuse only in the passenger compartment. On cars with engines MR20DE (2.0 l) and HR16DE (1.6 l) it is often duplicated in the engine compartment. To avoid guessing, check both places. Fuse locations for different years of manufacture are shown below.

Fuse box diagrams: where to look Fuel Pump?

Below are the current diagrams for Nissan Qashqai J10 (2007–2013). Please note that on cars before 2010 and after 2010, the location of the fuses may differ due to restyling.

Year of manufacture	Fuse box	Fuse number	Denomination (A)	Notes
2007–2010	Cabin (under the steering wheel)	F30	15	On machines with MR20DE can be duplicated in the engine compartment as EFI (20A).
2010–2013	Cabin (under the steering wheel)	F32	10	On restyled versions, the fuse is often combined with a relay.
2007–2013 (all)	Engine compartment (next to the battery)	Fuel Pump or EFI	20	May not be available on basic trim levels.

If you do not find the fuse according to the diagram, check fuel pump relay - it is often located nearby and can be the cause of the problem. On Qashqai J10 the relay is usually located:

• 🔌 In the interior fuse box (marked as R17 or Fuel Pump Relay).
• 🛋️ Under the rear seat, next to the fuel pump (on some versions).

How to distinguish a fuse from a relay?

The fuse is a small plastic insert with a metal jumper inside (transparent or colored). A relay is a box with legs and an inscription (for example, “12V 30A”).

Signs of malfunction: how to understand that a fuse has blown?

If the fuel pump fuse is blown, the car behaves unambiguously:

• 🚗 The car won't start, but the starter turns. The engine "grabs" air, but does not start.
• 🔊 No sound from fuel pump when you turn on the ignition (normally there should be a slight hum from under the rear seat).
• ⚡ The "Check Engine" light comes on on the dashboard., but the error may indicate other problems (for example, P0190 — open circuit of the fuel pressure sensor).
• 🔋 Voltage drop in the on-board network when trying to start (may drop to 9–10 V).

However, these same symptoms may indicate:

• 🔧 Malfunction of the fuel pump (brush wear, rotor jamming).
• 📉 Broken wiring or oxidation of contacts in the pump power circuit.
• 🔑 Problems with immobilizer (blocks fuel supply).

⚠️ Attention! If the fuse burns again after replacement, do not install a fuse of a higher rating - this will lead to melting of the wiring or failure of the fuel pump. The cause of the short circuit must be sought in the circuit!

Step-by-step instructions: how to check and replace the fuse?

To check and replace the fuel pump fuse on Nissan Qashqai J10 you will need:

• 🔧 Flat screwdriver (for removing the block cover).
• 🔍 Flashlight (to see fuse numbers).
• 📱 Multimeter or tester (to check voltage).
• 🔋 New fuse (the value must match the burnt one!).

Sequence of actions:

1. Turn off the ignition and remove the negative terminal from the battery (for safety).
2. Find the fuse box (interior or engine compartment, depending on modification).
3. Remove the unit coverby pressing the latches or prying with a screwdriver.
4. Find the fuel pump fuse according to the scheme (see table above).
5. Remove the fuse special forceps (available in the unit) or tweezers.
6. Check it visually: if the jumper is burned out, the part must be replaced.
7. Install a new fuse the same denomination.
8. Check the operation of the fuel pump: When the ignition is turned on, the sound of its operation should be heard (1–2 sec).

If after replacing the fuse the fuse burns out again, the problem lies deeper:

• 🔌 Short circuit in the circuit (check the wiring from the fuse box to the fuel pump).
• 🛠️ Fuel pump malfunction (may draw too much current).
• 🔋 Weight problems (oxidation of contacts on the body or fuel tank).

Common mistakes when replacing the fuel pump fuse

Even experienced car owners make mistakes that lead to repeated failure of the fuse or damage to the electronics. Here are the most common:

• ⚡ Installing a larger fuse (for example, 20A instead of 15A). This could burn out the fuel pump or wiring.
• 🔧 Ignoring Relay Test. If the fuel pump relay is stuck or fails, the new fuse will blow immediately after starting.
• 📉 Unverified contacts. Oxidized or burnt contacts in the fuse box lead to poor connections and repeated burnouts.
• 🚗 Replacing only the fuse without diagnosing the cause. If there is a short circuit in the circuit, a new fuse will last from a few seconds to minutes.

⚠️ Attention! On Nissan Qashqai J10 with engine MR20DE (2.0 l) fuel pump fuse is sometimes combined with a fuse main relay. If after replacing the car still does not start, check the main relay circuit (F10 in the cabin block).

Fuel pump circuit diagnostics: what to do if the fuse burns out repeatedly?

If the new fuse burns out immediately after installation, you need to check the entire fuel pump power circuit. Here is a step-by-step algorithm:

1. Check the fuel pump relay:
   • Remove the relay from the block.
   • Ring the contacts with a multimeter 85 And 86 (coil resistance should be ~70–120 Ohms).
   • If the relay does not “click” when 12V is applied to the contacts 85 And 86, replace it.
2. Ring the wiring:
   • Disconnect the fuel pump connector (under the rear seat).
   • Check the resistance between the positive wire and ground - it should be infinity (no short circuit).
3. Inspect the fuel pump:
   • Remove the fuel module and check for signs of melting or burning.
   • Measure the current consumption of the pump (the norm is 4–8 A). If above 10 A, the pump is faulty.

If you are not confident in your abilities, it is better to contact an auto electrician. A short circuit in the fuel pump circuit can lead to a fire in the wiring., so diagnosis must be carried out carefully.

FAQ: Frequently asked questions about the fuel pump fuse Nissan Qashqai J10

Is it possible to drive without a fuel pump fuse?

No! The fuse protects the circuit from overload. Without it, the risk of wiring melting or fuel pump failure increases significantly. If a fuse blows, you need to look for the cause, and not remove it from the circuit.

Which fuse to install if there is no inscription in the block Fuel Pump?

On some versions Qashqai J10 The fuel pump fuse may be labeled as EFI, FP or Injection. Check the diagram in your owner's manual or check all 10-15A fuses in the cabin and engine compartment.

Why does the fuse only blow when cold?

This may indicate increased resistance in the circuit at low temperatures (for example, oxidized contacts) or wear on the fuel pump (it consumes more current during cold starts). Check the contacts and measure the current consumption of the pump.

Is it possible to replace the fuse with an automatic one?

Technically yes, but not recommended. Automatic fuses (such as "bimetallic") may not operate in time during a short circuit, which will lead to damage to the wiring. Use only standard fuses.

Where to buy an original fuse for Qashqai J10?

Original fuses Nissan sold at dealerships (the article number depends on the denomination, for example, 28510-4M000 for 15A). Analogues: Littlefuse, Bussmann or Hella (the main thing is that the denomination and size match).
