Fuel pump fuse <em>Nissan Almera Classic</em>: location, check and replacement

Nissan Almera Classic (also known as N16 in the back B10) is one of the most popular sedans on the CIS secondary market. But even this reliable car has weak points, and the fuel pump fuse is a typical “candidate” for failure. If your car suddenly stalls and won’t start, while the starter turns, but there is fuel in the tank, this small but critical element may be the culprit.

In this article we will look at where the fuel pump fuse is located on Almera Classic, how to check it with a multimeter, what symptoms indicate a breakdown, and what to do if the problem remains after replacement. And also - common mistakes during diagnostics, which lead to unnecessary expenses for repairs.

Where is the fuel pump fuse located? Nissan Almera Classic?

B Almera Classic (2006–2012, engines QG15DE And QG18DE) the fuel pump fuse is located in interior fuse box. This block is located to the left of the steering column, under a plastic cover. To access:

1. Open the driver's door and sit in the seat.
2. Look down under the steering column - there you will see a rectangular cover with latches.
3. Gently pry the cover with a flathead screwdriver or your fingers and remove it.

Under the cover you will see a fuse and relay box. The required fuel pump fuse Almera Classic is marked «Fuel Pump» or «EFI» and denomination 15A (amps). Usually this is fuse number #30 or #31 (exact location depends on year of manufacture).

Important! On some versions Almera Classic (for example, with an engine QG18DE 2010–2012) fuse can be moved to additional unit under the hood. If it is not in the car, check the black plastic box next to the battery.

Symptoms of a faulty fuel pump fuse

Fuse problems appear suddenly and are often confused with a breakdown of the pump or relay itself. Here are the key signs that the fuse is at fault:

• 🔴 The car starts and immediately stalls (the starter turns, but the engine does not “get enough”).
• 🔴 When you turn on the ignition, you cannot hear the characteristic buzzing of the fuel pump (normally it lasts 2-3 seconds).
• 🔴 Lights up on the dashboard Check Engineand the scanner shows an error P0190 (fuel pressure sensor circuit malfunction).
• 🔴 The car twitches while driving, as if it is “choking” on fuel.

If at least one of these symptoms appears, first check the fuse. But be careful: the same signs may indicate fuel pump relay (it is located in the same block) or on broken wiring to the pump.

How to check a fuel pump fuse with a multimeter

To check you will need multimeter (or a simple 12V light bulb with wires). Follow the step by step instructions:

1. Turn off the ignition and remove the fuse from its socket (you can use tweezers from the fuse box).
2. Set the multimeter to mode calls (diode icon) or resistance measurements (200 Ohm).
3. Touch the probes to the fuse contacts. If it is working, the device will show 0 ohm (or beeps). If the fuse is blown, there will be resistance endless (on screen “1” or “OL”).

An alternative method is visual inspection. Bring the fuse to the light: if the jumper is inside torn or melted, it needs to be replaced.

If the fuse is intact, but the problem remains, check fuel pump relay (usually it is signed as Fuel Pump Relay) and socket voltage (must be 12V with the ignition on).

Step-by-step replacement of the fuel pump fuse

If the fuse is blown, it must be replaced with a new one. same denomination (15A). Under no circumstances install a “bug” (wire) or a fuse of a higher rating - this may lead to fire in the fuel system!

Replacement instructions:

1. Buy a new fuse 15A (any standard blade fuse will do, e.g. Bosch or Hella).
2. Turn off the ignition and remove the old fuse.
3. Insert the new fuse into the socket until it clicks (make sure it is firmly seated).
4. Turn on the ignition and listen: you should hear the sound of the fuel pump (buzzing in the rear seat area).
5. Start the car. If the engine starts and runs smoothly, the problem is solved.

If after replacement the fuse burns out again, this is a sign short circuit in the fuel pump circuit. In this case, you need to diagnose the wiring or the pump itself.

Why does the fuel pump fuse burn out: the main reasons

A fuse does not blow out just like that - it is always a consequence of another malfunction. Here are the most common reasons for Almera Classic:

Reason	How it manifests itself	What to do
Short circuit in wiring	The fuse blows immediately after replacement	Ring the wires from the fuse box to the fuel pump
Fuel pump wear (jamming)	Pump hums louder than usual before failing	Replace the fuel pump (part number for Almera Classic: 17040-4M500)
Water entering the fuel tank	The car jerks, the fuse burns out after refueling	Drain fuel, wash tank, replace filter
Faulty fuel pump relay	The fuse burns when the ignition is turned on	Replace the relay (part number: 25230-3M600)

If the fuse blows again - don't take risks and contact an auto electrician. Self-diagnosis of wiring without experience can lead to serious damage.

What happens if you ignore a blown fuse?

If you constantly replace the fuse without eliminating the cause, this can lead to melted wiring, failure of the fuel pump, or even a fire. For example, if there is a short circuit in the pump circuit, the wires can heat up to the melting point of the insulation, which can lead to a fire.

Common mistakes when diagnosing a fuel pump

Many owners Almera Classic They spend money on unnecessary parts due to incorrect diagnosis. Here are the typical mistakes:

• 🔧 They change the fuel pump without checking the fuse and relay. Pump cost - from 8,000 rubles, and the fuse costs 50 rubles.
• 🔧 Check the fuse “by eye” without using a multimeter. Sometimes the jumper inside remains intact, but the fuse no longer conducts current.
• 🔧 Ignore verification fuel pump mass (it is located under the rear seat, on the body). An oxidized ground contact gives the same symptoms as a blown fuse.
• 🔧 Forget to reset errors Check Engine after replacing the fuse. Even if the problem is solved, the error may remain in the ECU memory.

Before going to the service center, check everything in order: fuse → relay → ground → wiring → the pump itself. This will save you time and money.

How much does a fuse cost and where can I buy it?

Cost of fuse Nissan Almera Classic funny - from 30 to 100 rubles per piece. But it is important to buy quality parts to avoid recurring problems. Here's the best place to buy:

• 🛒 Auto stores (AutoDetail, existential, AutoSpetsCenter) - fuses Bosch, Hella or Nissan (original).
• 🛒 Online platforms (Wildberries, Ozon, AliExpress) - cheaper, but there is a risk of running into a fake.
• 🛒 Showdown - if you need to save money, but the fuses there are usually used (not the best option).

Article number of the original fuse Nissan: 24430-JK00A (but any standard 15A knife blade will do). If you buy non-original, take proven brands - Bosch or Littelfuse.

FAQ: Frequently asked questions about the fuel pump fuse

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

No. Without a working fuel pump, fuel will not be supplied to the engine, and the car simply will not start. If the fuse burns out on the way, you can temporarily replace it with a serviceable one with the same rating (for example, from a cigarette lighter), but only to get to the repair site.

Which fuse is responsible for the fuel pump on Almera Classic 1.6?

On most versions with engine QG16DE this is a fuse 15A with markings EFI or Fuel Pump, located in the cabin block under number #30. On some modifications (for example, 2011–2012) it may be numbered #15 in the engine compartment.

Why does the fuel pump not work after replacing the fuse?

Possible reasons:

1. Faulty fuel pump relay (check it by swapping it with a known good relay, for example from a fan).
2. Problems with wiring (open or short circuit).
3. Faulty itself fuel pump (you need to check the voltage at its connector).
4. Oxidized mass pump (clean the contact under the rear seat).

Is it possible to put a 20A fuse instead of 15A?

Absolutely not! The fuse is designed for a maximum current of 15A, and installing a more “powerful” one will lead to the risk of wiring melting or fire. If 15A constantly burns out, look for the cause (short circuit or faulty pump) rather than increase the rating.

Where is the fuel pump relay located on Almera Classic?

The fuel pump relay is located in the same interior fuse box as the fuse. It is usually signed as Fuel Pump Relay and has a number #5 or #6. To check it, you can swap places with the fan relay (they are often identical).
