Start of the trip from Nissan Juke It can turn into an unpleasant surprise if the engine suddenly stalls or does not start at all. Owners of this crossover often encounter a situation where the starter turns the engine, but the characteristic sound of the fuel pump is not heard. In 90% of cases, the problem lies in the burnout of the protective element in the power circuit, namely - fuel pump fuse.
Ignoring this problem can leave you stranded on the side of the road at the worst possible time, especially if the car is equipped with a turbocharged engine that requires constant fuel pressure. For most Nissan Juke models with 1.6 liter (HR16DE) and 1.6 DIG-T (MR16DDT) engines, it is critical to use a strictly 15A or 20A fuse, otherwise the wiring may melt.
In this article we will look in detail at where exactly the mounting block with the required fuse is located, how to correctly identify and replace it. You will learn not only about the mechanical replacement of the element, but also about the reasons that led to its failure in order to avoid a repetition of the situation in the future.
Location of mounting blocks on Nissan Juke
By car Nissan Juke The electricity distribution system is divided into two main units, each of which is responsible for certain groups of consumers. To find the right fuse, you need to understand your crossover's electrical architecture.
The first block is located in the engine compartment, next to the battery. This is the main power unit where high power relays and fuses are located, responsible for the operation of the generator, cooling fans and starter. The second unit is hidden in the cabin, usually on the driver or passenger side, and contains protection elements for low-current circuits, including lighting, power windows and the fuel system.
The fuel pump fuse is most often located in salon block, however, in some trim levels with powerful turbo engines it can be duplicated or transferred to the engine compartment. The exact location depends on the vehicle year and regional build specifications. You need to check both places if your first search doesn't yield any results.
Do not use excessive force when removing the panels, as the plastic clips on the Nissan Juke Quite fragile and easily broken if handled carelessly.
- 📍 Main mounting block: under the hood, to the right of the battery (for power circuits).
- 📍 Additional unit: in the cabin, behind the cover on the left side of the dashboard or behind the glove compartment.
- 📍 Pump relay: often located in the same block as the fuse, next to it.
⚠️ Attention: Before starting any work to find fuses, you must turn off the power to the car. Turn off the ignition and remove the key from the lock to avoid a short circuit when removing the elements.
- In the engine compartment
- In the cabin behind the glove compartment
- I don't know where they are
- I find it immediately according to the instructions
Fuel pump fuse identification
Once you reach the mounting block, you will see a variety of colorful elements. In order not to confuse the fuel pump fuse with the protection elements of the windshield wiper circuit or side lights, you must carefully study the diagram. A table with symbols is usually pasted on the block cover or on the inside of the glove compartment.
In the diagrams Nissan Juke The fuel pump fuse is often labeled as FUEL PUMP, F/P or INJ (injector). The current rating for this circuit is usually 15 or 20 amps. Fuse colors can vary: 15A is usually the blue element, and 20A is the yellow element. However, relying on color alone is dangerous, as colors may vary depending on the part lot.
Use special plastic tweezers, which often come with the unit, to carefully remove the element. Inspect the metal jumper inside the transparent housing. If it is intact and continuous, the fuse is working. If the jumper is torn or melted, the element is burnt out and requires replacement.
If you do not find the marking on the diagram or it has been erased, you can use a multimeter in dial mode. Attach the probes to the fuse contacts: if the device beeps or shows zero resistance, the circuit is intact. If the resistance is infinitely high, the element is faulty.
- 🔍 Look for the markings:
FUEL PUMP,F/P,INJ,IGN. - 🔍 Check the integrity of the metal arc inside the plastic case.
- 🔍 Use a multimeter for an accurate diagnosis if there is no visual damage.
☑️ Fuse diagnostics
Causes of burnout and problem diagnosis
Simply replacing the burnt-out element and continuing operation is a half-measure. If the fuse is blown, there is an overload or short circuit in the circuit. Understanding the cause will help prevent further failure and may possibly save your fuel pump from failure.
The most common reason is wear and tear fuel pump. Over time, the brushes inside the pump wear out, requiring more current than the rated current to rotate the armature. This creates a constant overload, which eventually causes the fuse to blow. In this case, replacing the fuse will help the car start for a short time, but the problem will return.
Another reason is wiring problems. Vibrations, temperature changes and an aggressive environment under the hood can damage the insulation of the wires going to the pump. If the wire touches the body or another wire, a short circuit occurs, which instantly blows the fuse.
Sometimes the problem lies in poor contact in the fuel pump connector. Oxidation of contacts increases resistance, which leads to local overheating and current surges. In this case, a burning smell or a melted plastic connector is often observed.
- 🛠️ Wear of fuel pump brushes: requires replacement of the pump itself.
- 🛠️ Short circuit in the wiring: requires checking the insulation and repairing the route.
- 🛠️ Poor contact in the connector: requires cleaning and treatment with contact lubricant.
What should I do if the new fuse immediately blows?
If, after installing a new element, it burns out in the first seconds of operation, do not try to install a fuse of a higher rating. This is a direct sign of a short circuit in the circuit. It is necessary to turn off the fuel pump and check the wiring for a short to ground. Continuing to attempt to start may result in a wiring fire.
Table of denominations and analogues
To correctly select a replacement, it is important to know the exact characteristics of the original element. Below is a table with data for the most common modifications Nissan Juke. Please note that the rating may vary depending on the year of manufacture and engine type.
| Engine model | Year of manufacture | Denomination (A) | Color | Location |
|---|---|---|---|---|
| 1.6 HR16DE (atmo) | 2010-2019 | 15 A | Blue | Salon block (F25) |
| 1.6 DIG-T (turbo) | 2010-2019 | 20 A | Yellow | Under the hood (F32) |
| 1.5 dCi (diesel) | 2011-2019 | 25 A | White | Cabin block (F30) |
| 1.2 DIG-T | 2013-2019 | 15 A | Blue | Salon block (F25) |
Using a fuse with the wrong rating is not permitted. If you install a 30A element instead of a 15A element, if there is a short circuit it will not work and the wiring may catch fire. If you set it to 10A, it will burn out constantly during normal pump operation.
In an emergency, when you don’t have the required fuse at hand, you can temporarily use an element of a lower rating, but only to get to the nearest store or service. Long-term operation with a lower rating will lead to frequent engine stops.
⚠️ Attention: Never use copper wire, a paper clip, or foil as a fuse. This deprives the circuit of protection and creates a direct threat of fire inside the car.
Using a fuse with a rating higher than the standard one is strictly prohibited, as this will deprive the circuit of protection and may lead to a fire in the wiring.
Step-by-step replacement instructions
The replacement process is extremely simple and does not require special skills or complex tools. The main thing is to act consistently and follow safety precautions. All you need is a new fuse of the correct rating and perhaps some tweezers or thin pliers.
Open the cover of the mounting block and find the required element according to the diagram. Pull out the blown fuse using tweezers by grasping it by the plastic housing. Do not touch the metal legs with your hands to avoid damaging the contacts, and do not use metal tools without insulation.
Insert the new fuse all the way into the same socket. Make sure it fits snugly and doesn't wobble. Close the unit cover and check the operation of the system. Turn on the ignition and listen to the pump start. If the sound appears, the problem is solved.
If after replacement the pump does not work, the problem may not be in the fuse, but in the relay itself or in a pump malfunction. In this case, you need to check the fuel pump relay by tapping it or replacing it with a known good one for testing.
- 🔧 Open the block cover and find the required fuse according to the diagram.
- 🔧 Remove the old element and insert the new one until it clicks.
- 🔧 Check the operation of the pump by turning on the ignition for 2-3 seconds.
If you change a fuse on the road and don’t have a suitable one at hand, you can temporarily use an element from a circuit that is not critical for driving (for example, from a cigarette lighter or radio) to get to the service.
When to contact specialists
Replacing the fuse is not always the solution to the problem. If the element burns out again and again, or if the pump does not turn on even with a good fuse, this is a signal of more serious problems. In such cases, independent repair may not bring results.
Service center specialists will conduct a complete diagnosis of the power system. They will check the pressure in the fuel rail, wear of the pump brushes, the condition of the relay and the integrity of the wiring. For this purpose, professional equipment is used, which is not available to the average owner.
It is especially important to contact a professional if you notice traces of melting on connectors or wiring. This indicates a serious short circuit or overheating that could damage other parts of the system. Simply replacing the fuse will not help here.
It is also worth contacting specialists if you do not have experience working with car electrical systems. Incorrect actions can lead to failure of the engine control unit (ECU), the repair of which will cost tens of times more than replacing a fuse.
What to do if both the fuse and the relay are burned out?
In this case, the problem is most likely in the fuel pump itself. A worn pump motor creates a short circuit that burns both the fuse and the relay contacts. It is necessary to replace the pump assembly and check the wiring for melting.
Frequently asked questions (FAQ)
Why doesn't the fuel pump on Nissan Juke turn on immediately after turning the key?
In the system Nissan Juke the pump runs for a few seconds when the ignition is turned on to build up pressure in the system, and then turns off. If the engine is not running, the pump will not run continuously. This is normal behavior of the engine management system.
Is it possible to use a larger fuse if the small one keeps blowing?
Absolutely not. Using a fuse with a higher rating (for example, 30A instead of 15A) deprives the circuit of protection. In the event of a short circuit, it is not the fuse that will burn out, but the wiring, which can lead to a fire in the car.
Where is the fuel pump relay located on a Nissan Juke?
The fuel pump relay is usually located in the same mounting block as the fuse. In the diagram it is designated as F/P or INJ. On some models it may be located in the engine compartment next to the main relay.
How to check the performance of a fuel pump without disassembling?
Turn on the ignition and put your ear to the rear of the passenger compartment (under the seat or under the trunk trim). You should hear a quiet buzzing sound for 2-3 seconds. If there is no sound, check the fuse, relay and power at the pump connector.
How much does it cost to replace a fuel pump fuse?
The cost of the fuse itself is minimal (usually 50-150 rubles). If the problem is in the wiring or pump, the cost of repair will depend on the complexity of the work and the need to replace parts. Diagnostics in the service will cost on average from 1000 to 3000 rubles.
