Where is the fuel pump fuse located on Nissan Almera G15

B Nissan Almera G15 (2012–2018) the fuel pump fuse is located in main mounting block, which is located inside the car. Exact location - to the left of the steering column, under the instrument panel. The unit is closed with a plastic cover with latches. To access:

1. Open the driver's door and sit in the seat.
2. Tilt the steering column down for comfort.
3. Pry off the fuse box cover with a flathead screwdriver or your fingers (the latches are on the sides).
4. Remove the cover - on its inside there is a diagram of the location of the fuses.

The fuse you are looking for is marked as Fuel Pump (15A) and usually has a number F20 or F21 (depending on the year of manufacture). On some modifications it may be called EFI (Electronic Fuel Injection). Attention: Do not confuse this with the cooling fan fuse (F18), which is located nearby!

What does a fuel pump fuse look like and its rating?

Fuel pump fuse Almera G15 - this is standard blade type fuse size mini-blade. Its denomination is 15 Amps (on some versions for Asian markets - 20 Amps). Visually, it is a plastic case with metal contacts and a transparent insert through which a jumper is visible. If the jumper is burned out (broken), the fuse must be replaced.

Fuse body color 15A — blue, on 20A — yellow. Important: never install a fuse with a different rating! For example, replacing with 25A may cause a fire in the wiring.

• 🔍 Original article: 28515-JK00A (for 15A) or 28515-4M00A (for 20A).
• 🛒 Analogues: Bosch 0392029130, Hella 8HD 009 158-151, Littlefuse ATM15.
• ⚠️ Fakes: Often there are fuses with a thin bridge that melts at the slightest load. Buy only from trusted sellers.

How to distinguish an original fuse from a fake?

Original fuses Nissan They have clear denomination markings on the case, uniform plastic color and burr-free metal contacts. Counterfeits often have blurry writing, uneven edges, and a bridge that is too thin.

Step-by-step instructions: how to check the fuel pump fuse

Before replacing the fuse, it must be checked. For this you will need multimeter (or a simple 12V test lamp). Follow the algorithm:

1. Turn off the ignition and disconnect the negative terminal of the battery.
2. Remove the fuse from the socket (you can use the tweezers included in the kit, which is usually located in the fuse box).
3. Set the multimeter to circuit test mode (diode or resistance icon).
4. Touch the probes to the fuse contacts. If the resistance is 0 ohm - the fuse is OK. If OL (break) - burned out.

Alternative method (without multimeter):

5. Turn on the ignition (without starting the engine).
6. Look at the fuse - if a broken jumper is visible through the transparent insert, it has burned out.
7. You can also temporarily replace a suspicious fuse with a known good fuse of the same rating (for example, from a cigarette lighter).

⚠️ Attention: If the new fuse burns out immediately after installation, do not try to install a fuse of a higher rating! This may cause a fire. The reason is most likely a short circuit in the wiring or a malfunction of the fuel pump itself.

Where is the fuel pump relay located and how to check it

Fuel pump relay Nissan Almera G15 located in the same mounting block as the fuse. It is usually designated as Fuel Pump Relay and has a number R17 or R18. Visually, a relay differs from fuses: it is a black or gray rectangular block with 4–5 legs.

To test the relay:

1. Remove the relay from its socket.
2. Look at the contacts: if they are melted or blackened, the relay is faulty.
3. For an accurate check, use a multimeter in resistance mode:
   • Between contacts 85 And 86 (coil) resistance should be 50–120 Ohm.
   • Between 30 And 87 (contacts) in good condition - OL (break), when 12V is supplied to the coil - 0 ohm.

If the relay is faulty, replace it with a new one with the part number 25230-JK00A or analogue (Bosch 0332019156, Hella 4RA 003 568-251). The cost of the original relay is about 500–800 rubles.

Typical causes of a blown fuel pump fuse

A fuel pump fuse doesn't just blow out - it's always a symptom of a more serious problem. Main reasons:

• ⚡ Short circuit in the circuit: most often occurs due to frayed or melted wiring under the rear seat (where the wires to the pump run).
• 🔥 Pump overload: If the fuel pump is worn out (for example, due to a clogged fuel filter), it consumes more current, which leads to a blown fuse.
• 💧 Moisture ingress: The mounting block may flood with water when washing or raining (especially if the seals are worn out).
• 🔌 Relay fault: If the relay is “stuck” in the closed state, it constantly passes current, which leads to overheating of the fuse.
• 🛠️ Errors after repair: incorrectly connected wires or installation of a fuse of the wrong rating.

If the fuse burns out again after replacement, you must ring the chain from the mounting block to the fuel pump. To do this:

1. Disconnect the fuel pump connector (located under the rear seat, under the hatch).
2. Check the resistance between the positive wire of the connector and ground - there should be more than 1 MOhm (if less - short circuit).
3. Inspect the wires for damage or melting.

⚠️ Attention: if, when checking the circuit, the multimeter shows 0 ohm between the positive wire and ground - this is a direct sign of a short circuit. Operate the vehicle in this condition dangerous!

How to replace a fuel pump fuse: step-by-step algorithm

Replacing the fuse with Nissan Almera G15 takes no more than 5 minutes, but it is important to do it correctly. Follow the instructions:

1. Turn off the ignition and remove the negative terminal from the battery (this is mandatory for safety!).
2. Remove the mounting block cover (as described above).
3. Find the fuse Fuel Pump (15A) and remove it with tweezers.
4. Install a new fuse of the same rating (blue for 15A, yellow for 20A).
5. Make sure that the fuse is seated tightly - it should not dangle in the socket.
6. Close the unit cover and connect the battery.
7. Turn on the ignition (without starting the engine) and listen: after 2-3 seconds you should hear the sound of the fuel pump running (buzzing under the rear seat).

If the pump does not hum after replacing the fuse, check:

• Serviceability of the fuel pump relay.
• Presence of voltage at the pump connector (must be 12V with the ignition on).
• The condition of the fuel pump itself (it may have burned out).

Frequently asked questions about the fuel pump fuse Nissan Almera G15

Is it possible to drive without a fuel pump fuse?

No! The fuse protects the circuit from overload and short circuit. If you remove it, the risk of a wiring fire or fuel pump failure increases significantly. As a last resort, you can temporarily install a fuse on 20A (if the original was on 15A), but only to get to the service station.

Why does the new fuse immediately blow?

This means that the circuit has short circuit. Most often the problem lies in:

• Wiring under the rear seat (frayed or melted wires).
• Faulty fuel pump (jammed rotor or interturn short circuit in the winding).
• Moisture has entered the mounting block or pump connector.

It is necessary to diagnose the circuit with a multimeter or contact an auto electrician.

How to check the fuel pump if the fuse and relay are good?

If the fuse and relay are OK, but the pump does not work:

1. Check the voltage at the pump connector (should be 12V with the ignition on).
2. Ring the pump ground - it must be securely connected to the body.
3. Remove the pump and check its operation from an external power source (12V).

If the pump does not hum and does not pump fuel, it is faulty and requires replacement.

Is it possible to repair the fuel pump relay?

Theoretically, you can try to disassemble the relay and clean the contacts, but in practice this is ineffective. A relay is an electromechanical device, and if its parts (for example, a contact group) wear out, restoration is impossible. It is better to replace the relay with a new one - its cost is low (from 300 rubles), and the reliability will be much higher.

Where to buy original fuse and relay for Almera G15?

Original spare parts can be purchased:

• From official dealers Nissan (quality guarantee, but high price).
• In trusted online stores (Exist.ru, Autodoc, Emex).
• In auto electrical stores (for example, Chip and Dip).

When purchasing, check the article number and check the compatibility table above.
