The situation when you turn the key in the ignition in the morning, and in response you only hear a quiet click or complete silence, is familiar to many owners of Japanese cars. Nissan Note is a reliable city hatchback, which, however, is not immune to technical failures, especially in harsh winter conditions or with high mileage. The "won't start" problem can be caused by anything from a dead key battery to a seriously damaged crankshaft sensor.
There is no need to panic at such a moment, since 80% of cases are resolved quickly and without an expensive call to a tow truck. You need to sequentially check the fuel supply, electrical and engine starting systems. In this article we will look at all the typical reasons why starter the motor does not turn or turns but does not grab, and we will give clear instructions on how to eliminate each of them.
Sometimes the problem lies in little things that we overlook, for example, the position of the gearshift lever or the condition of the contacts. Correct diagnostics will save you time and money, allowing you to avoid unnecessary visits to the car service center. Let's figure out what exactly happens to your car when it refuses to start.
Checking the battery and electrical system
The most common reason why Nissan Note won't start - it's weak battery. Even if the headlights are on, this may not be enough to operate a powerful starter, which requires a huge current at the moment of starting. In frosty weather, the battery capacity drops sharply, and if it is no longer new, the energy reserve may be critically low.
Pay attention to the nature of the sound when you turn the key. If you hear frequent clicking noises but the engine does not turn over, this is a sure sign of low voltage. In this case, you need to check the voltage at the terminals with a multimeter or try to “light it” from another car. If after starting the engine stalls immediately, the problem is definitely in the battery.
- 🔋 Check the electrolyte density or voltage (normal 12.6V and above).
- 🔌 Clean the terminals from oxides and white deposits to ensure good contact.
- ❄️ In severe frosts, remove the battery and bring it into a warm room at night.
Sometimes it is not the battery itself that is to blame, but poor contact on the ground or starter wiring. Inspect the thick black wire that runs from the battery to the body or engine. If it is damaged or weakened, the current will not reach the trigger. Starter is the heart of the launch, and its serviceability directly depends on the quality of the electrical connections.
⚠️ Warning: Do not attempt to push start the engine if you have an automatic transmission (CVT). This can lead to costly torque converter and planetary gear failure.
Malfunctions of the ignition system and immobilizer
If the starter turns the engine briskly, but the engine does not catch, the problem may be hidden in the ignition system or the starter lock. In modern cars Nissan An immobilizer is installed that reads the chip in the key. If the system does not recognize the key, it will block fuel or spark and the engine will not start.
Pay attention to the key or lock indicator on the dashboard. If it flashes or stays on after trying to start, it means the signal from the key is not getting through. Try using a spare key. If the car starts with the spare key, the problem is in the main key fob chip or in the antenna around the ignition switch.
- 🔑 Replace the battery in the key - a weak chip signal may not be read.
- 📶 Remove your mobile phone or other electronic devices that cause interference from the key.
- 🔄 Check if the steering wheel is locked (sometimes you need to turn the steering wheel slightly when turning the key).
The second important aspect is the spark plugs and coils. If there is no spark at the plugs, the fuel will not ignite. In older models Nissan Note (especially with a 1.4 l engine) ignition coils may fail. Unscrew one spark plug, press it against the ground and ask someone to turn the starter - there should be a bright blue spark.

- Starter problems
- Immobilizer/Key
- Fuel system malfunction
Problems with the fuel system and gasoline supply
If there is a spark, the starter turns, but the car does not start, you need to check whether fuel is entering the cylinders. The most common cause is failure fuel pump. When you turn the key to the “ON” position, you should hear a quiet whirring sound from under the rear seat for 2-3 seconds - this is the pump creating pressure in the rail.
If there is no sound, the fuel pump fuse or the pump motor itself may have blown. Also pay attention to the fuel filter. If it has not been changed for a long time, it could become completely clogged with dirt, blocking the access of fuel to the engine. In this case, the system pressure will be too low to start.
Another reason is clogged injectors. They can be so dirty that they do not spray fuel, but simply let it drip through. This often happens when using low-quality gasoline. In this case, professional cleaning at the stand or replacement of elements is required.
⚠️ Warning: If you smell a strong smell of gasoline from the exhaust but the engine does not start, stop trying to start immediately. This may indicate fuel overflow and a risk of fire if a spark hits a hot catalyst.
☑️ Checking the fuel system
Sensors and electronic control units
Modern Nissan Note is controlled by complex electronics, and the failure of one sensor can paralyze the operation of the entire engine. The critical element is Crankshaft position sensor (CPS). If it is faulty or its wiring is damaged, the ECU does not know what position the pistons are in and does not command fuel injection and spark.
This problem can only be diagnosed with a scanner. DPKV errors are often accompanied by the fact that the starter turns the engine for a very long time, but it does not start. Also, the throttle position sensor or mass air flow sensor (MAF) often fails, which leads to incorrect calculation of the mixture.
- 💻 Connect the OBD-II scanner and read errors (codes P0335, P0336, etc.).
- 🔍 Visually inspect the sensor connectors for oxides or broken contacts.
- 🧹 Clean the throttle valve if it is heavily contaminated with carbon deposits.
What to do if the crankshaft sensor fails on the road?
If the DPKV sensor is broken, it is impossible to start the engine in the normal way. The only temporary solution is to replace the sensor with a new one. In some cases, carefully cleaning the sensor pin from dirt helps, but this rarely has a long-term effect. It's best to have a spare sensor in the trunk if you frequently travel to remote areas.
Mechanical faults of the starter and ignition switch
Sometimes the problem is purely mechanical. If when you turn the key you only hear a single click or nothing happens, but the battery is working, it may be your fault. starter. Inside it, the solenoid relay may wear out, the windings may burn out, or the bendix that engages the engine flywheel may wear out.
It is also worth checking the ignition switch. The contacts inside the mechanism burn out over time, and the signal simply does not reach the starter. Try moving the key in the lock when trying to start. If the engine starts at a certain position of the key, then the problem is in the contact group of the lock.
| Symptom | Probable Cause | Solution |
|---|---|---|
| Quiet click, starter does not turn | Solenoid relay or battery | Check battery, replace relay |
| The starter turns but does not engage | Bendix wear | Starter repair or replacement |
| Check Engine Light Is On | Sensor or ECU error | Diagnostics with a scanner |
| Key icon flashing | Immobilizer problem | Replacing the key battery or flashing it |
| Smells gasoline but won't start | Fuel overflow | Blowing cylinders, checking injectors |
In some rare cases, the problem lies in the fuses. Locate the fuse box under the hood and in the passenger compartment. Check the ignition fuse (usually labeled IGN or EFI). If it burns out, replace it with a new one with the same amperage.
If the starter hums but does not turn the engine, try lightly tapping the starter housing with a hammer or wrench while a helper holds the key in the starting position. This can temporarily free up stuck brushes and get the engine running until the tow truck arrives.
Features of launching hybrid versions of Nissan Note e-Power
Version owners Nissan Note e-Power are faced with starting features, since there is no classic internal combustion engine that rotates directly from the starter. The engine here works only as a generator to charge the traction battery. If the machine does not turn on, the problem may be in the high voltage system.
When you press the START button, if only the sound of the fans is heard, and the machine is not ready to move, check the charge level of the traction battery. Also pay attention to the indicators on the instrument panel. In hybrids, errors in the engine management system are often triggered, which block the generator from starting.
If it is discharged, the electronics will not be able to activate the high voltage battery power relays. Therefore, diagnosing a hybrid begins with checking a conventional battery, and not just analyzing engine errors.
For hybrid versions of the Nissan Note, it is critical to keep the 12-volt battery charged, as without it the high-voltage system will not activate and the car will not move, even if the traction battery is 100% charged.
FAQ: Frequently asked questions
What to do if your Nissan Note won't start in cold weather?
First, warm up the battery by turning on the headlights for 30 seconds, then try starting it. If this does not help, use a “lighter” from another car or a warm box. Check the engine oil - thick oil creates resistance for the starter.
Why does the car start but immediately stall?
This is often due to a faulty MAF sensor, a clogged throttle body, or problems with the immobilizer. The idle speed control may also be faulty. Computer diagnostics is required.
Is it possible to push start a Nissan Note?
If you have a manual transmission, yes. If it is a CVT or an automatic transmission, it is strictly forbidden, this will lead to transmission failure.
How much does it cost to repair a starter on a Nissan Note?
Price depends on model and region. Restoring an old starter will cost less (from 3,000 rubles) than buying a new one (from 15,000 rubles). Replacement work takes about 1-2 hours.
How to check the serviceability of a fuel pump without equipment?
Listen to the sound coming from under the rear seat when you turn on the ignition. If there is no sound, remove the fuse and check it. You can also gently tap the tank, sometimes this helps revive a stuck pump.
Remember that regular maintenance is the best prevention of such problems. Change filters, check the battery and monitor the condition of the spark plugs. In 90% of cases, the fault starts can be eliminated independently, without resorting to the services of a tow truck.. Be attentive to the sounds and signals of your car, and it will serve you for a long time.
