Nissan Almera Classic is one of the most popular sedans on the secondary market, but even such a reliable car has typical malfunctions. One of them is the sudden stopping of the engine or refusal to start, which is often associated with fuel pump fuse. If your car stalls while driving or the starter turns, but the engine does not “get enough”, the problem may lie in this small but critical element.

In this article you will find exact fuse location diagrams for different generations Almera Classic (including restyled versions), learn how to check it without special tools, and what to do if replacement does not help. We will also look at unique “symptoms” of a fuel pump malfunction on this particular model, which are often confused with problems in the ignition system or ECU.

Why is it important to know where the fuel pump fuse is located?

Fuel pump fuse Nissan Almera Classic - This is the “weak link” that protects the circuit from short circuits and overloads. Unlike a relay, which simply opens its contacts, a fuse burns out physically, breaking the chain. If it fails, the fuel pump stops pumping fuel, and the engine either does not start or stalls a few seconds after starting.

The main reasons why this fuse may blow are:

  • 🔥 Short circuit in the fuel pump circuit (for example, due to damaged wiring or oxidized contacts).
  • ⚡ Power surges in the on-board network (often after “lighting up” from another car).
  • 🛢️ Wear of the pump itself, which begins to consume more current and overloads the circuit.
  • 💧 Moisture ingress into the fuse box (relevant for cars with mileage >150 thousand km).

Many owners Almera Classic They are faced with the fact that after replacing the fuse it burns out again. This signals more serious problem - for example, a malfunction of the pump itself or a ground break. In such cases, a comprehensive diagnosis is required.

⚠️ Attention: If the fuel pump fuse blows immediately after installing a new one, don't try to bug (jumper made of wire or foil). This may lead to a fire in the wiring or failure of the ECU!

Where is the fuel pump fuse located? Nissan Almera Classic

Depending on the year of manufacture and configuration Almera Classic (pre-styling B10 or restyling N16), the fuel pump fuse may be located in different places. Below are the exact diagrams for each version.

1. Nissan Almera Classic B10 (2000–2006)

On the first generations, the fuel pump fuse is located in main fuse box, which is in the cabin, under the instrument panel on the driver's side. To get to it:

  1. Open the driver's door and sit in the seat.
  2. Locate the plastic cover under the steering wheel (to the left of the pedals).
  3. Release the latches and remove the cover.
  4. The fuse box will be immediately visible - it is white or gray.

The fuse you are looking for is marked as F/P 15A (in some diagrams - Fuel Pump or FP). Its denomination is 15 Amps. There is usually a diagram with signatures on the block cover, but if it is erased, refer to the photo below.

There is a diagram on the block cover where the fuel pump fuse is labeled "15A F/P" (usually the 3rd or 4th on the top row). If there is no diagram, look for a fuse labeled "Fuel Pump" or check all 15 Amp fuses one at a time.

2. Nissan Almera Classic N16 (2006–2012, restyling)

On restyled versions, the fuse box was moved to engine compartment. It is located next to the battery, under a plastic cover. The fuel pump fuse is marked here F/P 20A (the rating has been increased to 20 Amperes!).

To find it:

  1. Open the hood and locate the fuse box to the right of the battery.
  2. Remove the cover by pulling it up.
  3. There will be a diagram on the inside of the lid. Look for the inscription Fuel Pump or FP 20A.

If there is no diagram, refer to third fuse in the second row (counting is done from left to right). Also on Almera Classic N16 may be nearby fuel pump relay (denoted as Fuel Pump Relay), which is worth checking if replacing the fuse did not help.

How to check the fuel pump fuse: step-by-step instructions

If you suspect the problem is with the fuse, you can check it without special tools. You only need spare fuse (preferably the same value) or a multimeter.

Turn off the ignition and remove the key from the lock

Locate the fuse box (see diagrams above)

Prepare a spare fuse (15A or 20A)

Take a flashlight to inspect the contacts-->

Method 1: Visual inspection

The easiest method is to remove the fuse and hold it up to the light:

  1. Remove the fuse using tweezers (usually built into the block cover).
  2. Look at the metal plate inside. If she torn or melted, the fuse has blown.
  3. Also check contacts in the block - they should not be oxidized or burnt.

If the fuse is intact, but suspicions remain, proceed to checking with a multimeter.

Method 2: Check with a multimeter

For this method you will need a tester in “calling” mode:

  1. Set the multimeter to circuit test mode (diode or buzzer icon).
  2. Touch the probes to the fuse contacts. If it is working properly, the device will emit a beep.
  3. If there is no signal, the fuse is burnt out and needs to be replaced.

You can also measure the voltage at the contacts of the unit (with the ignition on). On one contact there should be +12V, on the other - 0V. If there is no voltage, the problem may be an open circuit or a faulty relay.

⚠️ Attention: If the fuse blows immediately after replacement, do not try to restart the engine - this may damage the ECU. First check the circuit for short circuit!
💡

If you don't have a multimeter at hand, you can use a 12V light bulb with wires. Connect it to the fuse contacts: if the light is on, the fuse is good.

What to do if replacing the fuse does not help

If after replacing the fuse the fuel pump still does not work, the problem may lie in:

  • 🔌 Fuel pump relay (located in the same block, designated as Fuel Pump Relay).
  • 🔋 Wiring (open or short circuit in the pump power circuit).
  • 🛢️ The fuel pump itself (brush wear, rotor jamming).
  • 📶 Masse (poor contact with body on Nissan Almera Classic often causes unstable pump operation).

Checking the fuel pump relay

Relay on Almera Classic located next to the fuse. To check it:

  1. Remove the relay from the block (usually it is black with the inscription Fuel Pump Relay).
  2. Swap it with a known good relay (such as the fan or headlight relay).
  3. Try starting the engine. If it starts, the relay is faulty.

You can also check the relay with a multimeter:

  • Contacts 85 And 86 (managers) must have resistance 50–120 Ohm.
  • When submitting +12V to contacts 85 And 86 contacts 30 And 87 must be closed (checked by continuity).

Checking the fuel pump

If the fuse and relay are good, but the pump does not pump fuel, check it directly:

  1. Remove the back seat and locate the gas filler door.
  2. Disconnect the pump power connector.
  3. Connect to pump contacts +12V And mass from the battery. If the pump does not work, it is faulty.

On Nissan Almera Classic a common problem with oxidation of contacts in the pump connector. Clean them and check the voltage on the wires with the ignition on (there should be 12V).

💡

If the pump works when connected directly to the battery, but not in normal mode, the problem is in the wiring or the computer.

Typical mistakes when finding and replacing a fuse

Many owners Almera Classic make the same mistakes, which can lead to serious damage. Here are the most common:

  • ❌ Using the wrong fuse rating (for example, 20A instead of 15A). This may cause the wiring to overheat.
  • ❌ Replacing a fuse without checking the cause of combustion. If the circuit is closed, the new fuse will blow immediately.
  • ❌ Ignoring relay. Often the problem lies with it, and not with the fuse.
  • ❌ Checking the pump without removing pressure in the fuel system. This is dangerous - gasoline may spray out under pressure!

Another common mistake is Confusing the fuel pump fuse with the fan fuse. On Almera Classic B10 they are located next to each other and have the same rating (15A). Always check the diagram on the unit cover!

⚠️ Attention: If you replace the fuse and the engine still won't start, do not turn the starter for more than 5 seconds. This can drain the battery or flood the spark plugs. Pause 30 seconds between attempts.

How to extend the life of the fuse and fuel pump

To avoid repeated problems with the fuse and fuel pump on Nissan Almera Classic, follow these guidelines:

  • 🔧 Check regularly contacts in the fuse box - clean them from oxidation.
  • ⚡ Follow on-board voltage. Surges (eg due to a faulty alternator) will shorten the life of the fuses.
  • 🛢️ Refuel at proven gas stations - bad fuel accelerates pump wear.
  • 🔋 Check before winter battery charge. A discharged battery causes voltage drops, which can cause the fuse to blow.

It also costs periodically (every 30–50 thousand km) clean the fuel pump screen. On Almera Classic it often gets clogged, causing the pump to overload and overheat. This may result in increased current consumption and blown fuse.

💡

If you often drive with an almost empty tank, the fuel pump will overheat and wear out faster. Try to keep the fuel level above 1/4.

FAQ: Frequently asked questions about the fuel pump fuse

Is it possible to drive without a fuel pump fuse by installing a jumper?

No! This is extremely dangerous. The fuse protects the circuit from short circuit. Without it, wiring, relays, or even the ECU may burn out. If the fuse burns out repeatedly, look for the cause (short circuit, faulty pump), and do not install a bug.

Which fuse should I use - 15A or 20A?

Depends on model:

  • Almera Classic B10 (2000–2006) — 15A.
  • Almera Classic N16 (2006–2012) — 20A.

Using a fuse with a different rating may result in a fire or damage to the pump.

Where is the fuel pump relay located?

The relay is located in the same block as the fuse. On Almera Classic B10 - this is a black relay with the inscription Fuel Pump Relay (usually the second or third in a row). On N16 - next to the fuse FP 20A.

Why does the fuse burn out immediately after replacement?

This speaks of short circuit in the chain. Reasons:

  • Damaged wiring (frayed wires under the carpet or in the engine compartment).
  • Faulty fuel pump (jammed rotor).
  • Breakdown in the relay.

You need diagnostics with a multimeter or contact an auto electrician.

Can the fuel pump fuse blow due to a dead battery?

No, directly - no. But if the battery is discharged and you are trying to start the engine, the starter consumes a lot of current, which can cause a voltage drop in the on-board network. In rare cases, this can lead to blown fuses. Most often the problem is in the pump itself or the wiring.
