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

Nissan Almera Classic (especially in the back N16) is one of the most popular foreign cars on the Russian secondary market. But even such a reliable car has typical malfunctions, and one of them is a fuel pump failure due to a blown fuse. If your car suddenly stalls or refuses to start, and the starter spins “idling,” the problem may lie in this small but critical element.

In this article we will look at where is the fuel pump fuse located on Almera Classic, how to check it without a tester, what signs indicate a malfunction, and why this problem cannot be ignored. You will also learn which fuses are suitable for replacement, how to avoid common diagnostic errors, and what to do if replacement does not help. The material is based on the experience of auto electricians and owners Nissan with a mileage of 100 thousand km.

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

B Almera Classic (models 2006–2012) the fuel pump fuse is located in fuse box under the hood. This is a typical location for most cars Nissan that period. However, many owners confuse it with the fuel pump relay or look for it in the interior - this is a mistake.

To get to the block:

• 🔧 Open the hood and find the black plastic box next to the battery (driver's side).
• 📌 There should be a diagram with fuse numbers on the block cover. We are looking for an inscription Fuel Pump or FP (on some versions - EFI).
• 🔍 The fuel pump fuse is usually rated 15A and is denoted as F19 or F20 (depending on the year of manufacture).

On some modifications Almera Classic (for example, with an engine 1.5 l QG15DE) the fuse may be in additional block under the dash on the passenger side. To check this, you will have to remove the plastic trim under the glove compartment.

Signs of a faulty fuel pump fuse

A blown fuse manifests itself unambiguously, but its symptoms are often confused with a breakdown of the pump or relay itself. Here are the key signs:

• ⚡ Car won't start, but the starter turns (no fuel supply).
• 🔊 When you turn on the ignition I can't hear the fuel pump whirring (normally it lasts 2–3 seconds).
• ⚠️ The dashboard may light up Check Engine, but not always (depending on the ECU version).
• ⛽ If the fuse blows periodically, the car may stall while driving and start again after cooling.

Important: if the fuse blows immediately after replacement, the problem lies deeper - perhaps short circuit in the pump circuit or a malfunction of the pump itself. In this case, diagnostics with a multimeter is required.

⚠️ Attention! Do not confuse a faulty fuse with fuel pump relay failure (it clicks when the ignition is turned on). The relay is located in the same block, but has a different number (usually R17).

How to check the fuel pump fuse without a tester?

If you don't have a multimeter at hand, you can check the fuse visually or using the “control”. Here are 3 working ways:

1. Visual inspection: Take out the fuse and look at the light - if the thread inside is burned out or the body is melted, the part must be replaced. However, sometimes a thread break is not noticeable, so this method is not always reliable.
2. Checking for spark:
   • Turn on the ignition (do not start the car!).
   • Remove the fuse and briefly short-circuit its contacts in the block with a screwdriver (sharp metal object).
   • If the relay clicks and the pump hums when it closes, the fuse has blown.

⚠️ Attention! This method is risky - if you close it inaccurately, you can burn the wiring or the ECU. Use it only as a last resort!

Replacing with a known good one: Take a fuse with the same rating (15A) from another circuit (for example, from the cigarette lighter) and install it in place of the “suspect”. If the car starts, the problem is solved.

If the fuse is intact, but the pump does not work, check:

• 🔌 Fuel pump relay (swap with a similar one, for example, with a fan relay).
• 🔋 Power supply at pump connector (you need a multimeter).
• 🛢️ The fuel pump itself (the winding may jam or burn out).

Step-by-step instructions for replacing the fuse

Replacing the fuel pump fuse with Nissan Almera Classic takes no more than 5 minutes. You will need:

• 🔧 Flat screwdriver (for removing the block cover).
• 🔄 New fuse on 15A (it's better to take the original Nissan or a high-quality analogue, for example, Bosch or Hella).
• 📸 Flashlight (if you work in the dark).

Procedure:

If after replacement the fuse burns out again, do not install a fuse of a higher rating (for example, 20A instead of 15A) - this may cause a fire! In this case, look for the cause in the pump power circuit or the pump itself.

Table: Compatible fuses for Nissan Almera Classic

Not all fuses are the same - cheap Chinese analogues may make poor contacts or overheat. The table below shows the tested options:

Manufacturer	Article	Denomination	Notes
Nissan (original)	28510-4M000	15A	The best choice, but expensive (about 300–500 rubles).
Bosch	1 987 314 034	15A	High-quality analogue, suitable for most foreign cars.
Hella	8EA 008 631-431	15A	A reliable brand, often used in services.
Littlefuse	ATM 15	15A	A budget option (about 50 rubles), but time-tested.
Unnamed (China)	—	15A	Not recommended - possible problems with contacts.

Important: Fuses Nissan Almera Classic have a standard size ATO/ATM (miniature knife). Don't confuse them with Mini or Maxi - they won't fit!

Typical mistakes when diagnosing and replacing

Even experienced drivers sometimes make mistakes that complicate repairs. Here are the most common:

• 🔍 Checking the fuse only, no relay. The fuel pump relay fails just as often as the fuse, but it is often ignored. Swap them with another relay (such as the cooling fan) to test.
• 🔌 Using bugs. Some drivers insert a wire or coin instead of a fuse - this direct path to fire! The fuel pump circuit is rated at 15A, and excess current can melt the wiring.
• 🛢️ Ignoring fuel level. If the tank is less than 5 liters, the pump may not buzz when the ignition is turned on (it will not pump air). Always check the fuel level before diagnosing.
• 🔧 Incorrect fuse installation. The fuse should fit tightly, without play. If the contacts are oxidized, clean them with sandpaper.

Another common mistake is replacing the fuse without finding the cause. If it burns out repeatedly, the problem may be:

• Short circuit in the wiring harness (often frayed under the rug near the gas tank).
• Malfunction of the fuel pump itself (jammed rotor or interturn short circuit in the winding).
• Problems with ground (check the fastening of the negative wire to the body).

What to do if replacing the fuse did not help?

If after replacing the fuse the fuel pump still does not work, follow the algorithm:

1. Check the fuel pump relay:
   • Locate the relay in the mounting block (usually R17).
   • Swap it with a known good one (for example, a headlight relay).
   • If the pump works after replacement, buy a new relay (Nissan art. 25230-4M000).
2. Ring the power circuit:
   • Remove the back seat and get to the fuel pump connector.
   • Check with a multimeter for presence 12V on the pink wire (with the ignition on).
   • If there is no voltage, the problem is in the wiring or the ECU.
3. Check the fuel pump itself:
   • Disconnect the pump connector and apply 12V direct from the battery (plus to the pink wire, minus to the black).
   • If the pump does not hum, it is faulty and requires replacement.
   How to check the fuel pump without removing the tank?

   If the pump does not hum when connected directly to 12V, but the fuse and relay are good, try tapping the tank with a hammer (not too hard!). Sometimes the pump “sticks” due to dirt in the tank, and tapping it helps to wedge it. If this works, get ready to replace the pump soon, as its resource has been exhausted.

4. ECU diagnostics:

   If all the previous steps did not help, the problem may be engine control unit. Connect a diagnostic scanner (for example, ELM327) and check for errors. Typical codes for Almera Classic:

   • P0230 — Fuel pump circuit malfunction.
   • P0171 - lean mixture (may be due to low fuel pressure).

If you are not confident in your abilities, it is better to contact an auto electrician. Diagnosing the fuel pump and its circuit requires experience, especially if the problem lies in the wiring or ECU.

FAQ: Frequently asked questions about the fuel pump fuse Nissan Almera Classic

Is it possible to drive without a fuel pump fuse if you install a bug?

❌ Absolutely impossible! The fuse protects the circuit from overload. Without it, a short circuit can burn out the wiring, relay, or even the gas tank. The worst case scenario is a fire. If the fuse blows repeatedly, look for the cause rather than bypass the protection.

What fuse can be temporarily used instead of a blown one if there is no 15A?

As a last resort, you can put a fuse on 10A (for example, from dimensions), but just for the trip to the store. Do not use fuses rated 20A or higher - this is dangerous! You can also temporarily “borrow” a fuse from a circuit that is not critical to driving (for example, a cigarette lighter or radio).

Why does the fuel pump fuse blow when the ignition is turned on?

This is a typical sign short circuit in the chain. Most often the problem is:

• Wiring under the rear seat (frayed wires).
• The fuel pump itself (winding short circuit).
• Pump connector (oxidation or moisture ingress).

To diagnose, disconnect the connector from the pump and check whether the fuse blows when the ignition is turned on. If not, the problem is in the pump. If yes, look for a short circuit in the wiring.

Where to buy an original fuse for Nissan Almera Classic?

Original fuses Nissan (art. 28510-4M000) can be found:

• At official dealerships (expensive, but reliable).
• In online stores (Exist.ru, Autodoc, Kolesa-darom).
• In large auto stores (for example, AutoSpetsCenter or IXORA).

Cost - from 200 to 500 rubles. If you don't have the original, take it Bosch or Hella.

Can the fuel pump fuse blow due to bad fuel?

❌ No, the fuse does not blow due to bad gasoline. It protects the circuit from overcurrent, not from fuel quality. However, bad gasoline can damage the pump itself (for example, due to impurities clogging the filter). If after refueling at a questionable gas station the car begins to stall, check fuel filter And fuel pump mesh.
