A situation where, when you turn the key in the ignition switch, you hear only a click or complete silence, and the engine Nissan Almera Classic shows no signs of life, is familiar to many car owners. This is an unpleasant surprise that often happens at the most inopportune moment, making you nervous and looking for ways to solve the problem. There can be many reasons for this behavior: from a banal dead battery to a complex breakdown of the retractor relay or the starter itself.
In most cases, the problem lies in the electrical circuit or mechanical wear of the starting system components. Starting system is a complex mechanism where each element performs its own function, and the failure of any link paralyzes the operation of the entire car. It is important to understand that ignoring symptoms or trying to "overdo" turning the key can lead to even more serious damage to the wiring or engine.
Primary diagnostics: battery and terminals
The first step when you hear that the starter is not responding to a command is to check the condition of the power source. Battery is the most vulnerable element in the starting chain, especially if the car has been sitting idle for several days or weeks. During the cold season, the battery capacity decreases, and even if it seems to be in good condition, it may not provide sufficient current for cranking. engine flywheel.
Inspect the visual condition of the terminals and wires going to the battery. Oxidation of the contacts creates a high contact resistance, due to which the voltage simply does not reach the starter. Even if the instrument panel lights come on, this does not guarantee that there is sufficient current under the load. The starting current requires tens of times more energy than operating lighting or a radio.
Check the tightness of the tips to the battery poles. If you find a white or greenish coating, it must be cleaned with sandpaper or a special brush until it has a metallic shine. The contacts should then be treated with conductive grease or lithol to prevent re-oxidation.
Don't forget to check the electrolyte level in the banks if you have a serviceable battery. A drop in level can lead to sulfation of the plates and loss of capacity. In modern maintenance-free batteries, you should focus on the “eye” indicator or measure the voltage with a multimeter.
- ⚡ Measure the voltage at the terminals: the norm is 12.6 V, when starting it should not fall below 9.5 V.
- 🔧 Clean the terminals from oxides and check the mechanical tightening of the nuts.
- 🔦 Inspect the battery case for cracks or swelling.
⚠️ Attention: Never try to start a car by “push” or tow if you have an automatic transmission (automatic transmission). This is guaranteed to lead to destruction of the torque converter and costly repairs.
Checking the ignition switch and contact group
A common cause of startup failure is Nissan Almera Classic is wear of the ignition switch contact group. Over time, under the influence of high currents, the contacts inside the mechanism burn out or oxidize, ceasing to transmit a signal to the starter. When you turn the key, you can hear a clicking sound in the area of the steering column, but no voltage is supplied to the starter.
To exclude this cause, it is necessary to check the presence of voltage on the starter control wire immediately when the key is turned. To do this, you will need a multimeter or a test lamp. If when you turn the key to the “Start” position there is no voltage on the control wire, the problem lies higher up the circuit.
Sometimes the problem is solved by simply treating the contact group with contact aerosol. However, if the mechanism is physically worn out, the lock will need to be replaced or the contact group repaired. On Nissan Almera Classic This is a common fault as the lock is used daily.
Pay attention to how the steering wheel behaves when you turn the key. If it is blocked and does not allow you to turn the key, this may be a signal that the lock cylinder or the steering wheel locking mechanism is broken.
- 🔑 Check the key play in the ignition switch when trying to start.
- 💡 Turn on the headlights and try to start the engine: if they dim but do not go out, the problem is not with the battery.
- 🔌 Check the reliability of the chip on the ignition switch.

Diagnostics of the solenoid relay and traction solenoid
If the battery is working properly, the voltage reaches the starter, but it still does not turn, the culprit may be solenoid relay. This unit is responsible for connecting the bendix to the flywheel and supplying the main current to the starter motor. The characteristic sound in this case is a single loud click, followed by silence.
Powerful contacts are closed inside the relay. Over time, these contacts burn out and current stops flowing to the starter motor. In some cases, the relay can be repaired by replacing the contacts or cleaning them, but most often a complete replacement of the assembly is required. On Nissan Almera Classic The retractor relay is often assembled with the starter, which complicates repairs.
Try gently tapping the starter housing with a hammer or screwdriver while attempting to start. Sometimes this helps to temporarily restore contact inside the relay or bendix, and the car will start. This is only a temporary measure to get to the service.
It is important to check the ground going to the starter housing. If the ground contact is poor, the relay may operate (click), but the engine will not turn due to lack of current.
- 🔨 Try to “reanimate” the solenoid relay with light blows.
- 🔌 Check the reliability of the contact on the relay power bolt.
- 📏 Measure the voltage drop across the ground circuit during the startup attempt.
☑️ Checking the solenoid relay
Mechanical faults of the starter itself
When the electrical part has been checked and is working properly, the cause may lie in the mechanics of the starter. Brushes wear, commutator burning or armature jamming - all this leads to electric motor It just can't rotate. The brushes wear out over time and contact with the commutator is lost.
It is also possible that the armature bushings (bearings) may wear out. If the bushings are worn out, the armature may touch the stator, causing jamming. In this case, you may hear a grinding or cracking sound, but there will be no rotation. The starter Bendix may also fail: its overrunning clutch may jam or, conversely, slip without transmitting torque to the flywheel.
For accurate diagnosis, the starter must be removed from the vehicle. After dismantling it, you need to check it on a stand or supply power directly from the battery. If, when 12 volts are supplied to the power contact, the starter does not turn, it must be repaired or replaced.
Pay attention to the condition of the Bendix gear. If the teeth are worn or chipped, they will not engage the flywheel. In this case, the starter will idle with a characteristic squeal, but the engine will not start.
- ⚙️ Check the condition of the Bendix gear for chips and wear.
- 🔍 Inspect the armature manifold for heavy carbon deposits or scoring.
- 🛠 Check the mobility of the armature inside the stator, it should rotate freely.
What to do if the bendix is stuck?
If the bendix is stuck, the starter may burn out when trying to start. In this case, you need to replace the bendix or the entire assembly, since repairing the overrunning clutch is often impractical.
Wiring and fuse problems
Starting circuit on Nissan Almera Classic has its own characteristics, and a broken wire or blown fuse can completely block the starter from working. Often the fuse responsible for the ignition circuit or the solenoid relay blows. It is necessary to check the fuse box in the passenger compartment and under the hood.
In addition to fuses, it is worth paying attention to the condition of the power cables. The thick wire running from the battery to the starter may have internal damage or corrosion under the insulation. This creates high resistance, and when you try to start, the correct voltage is not supplied to the starter.
Check the starter relay in the mounting block. It may be in the “on” position or have burnt contacts inside the case. Replacing the relay with a known good one is a quick way to test this hypothesis.
Sometimes the problem lies in poor contact in the wiring connectors. Moisture and vibration eventually destroy the contacts, which leads to an interruption of the circuit. Inspect all connectors along the path from the ignition switch to the starter.
| Chain element | Symptom of malfunction | Remedy |
|---|---|---|
| Starter fuse | Complete silence when turning the key | Replacing the fuse with a similar one |
| Starter relay | No click of the solenoid relay | Replacing the relay or checking the coil |
| Power cable | Voltage drop at startup | Replacing or stripping cable contacts |
| Battery terminals | Oxidation, heating at start-up | Cleaning and tightening terminals |
Before removing the starter, be sure to disconnect the negative terminal of the battery to avoid a short circuit when disconnecting the power wires.
Start blocking system (Immobilizer)
On modern cars, including Nissan Almera Classic, the immobilizer system plays a critical role. If the control unit does not see the chip in the key, it blocks the starter circuit. In this case, you may hear the relay click, but the starter will not work, or will work for a very short time.
Sometimes the problem occurs due to a low battery in the key (if it is a chip key with a remote control) or damage to the chip itself. Malfunctions of the immobilizer antenna located around the ignition switch are also possible. In such cases, the lock or key indicator may flash on the instrument panel.
Try using a spare key. If the car starts with the spare key, then the problem is with the main key. In this case, you will need to reflash the chip or replace the key at the dealer or specialized technicians.
In rare cases, the immobilizer control unit itself or the wiring to it may fail. This requires professional diagnosis using a scanner to read the error codes.
- 🔑 Check the functionality of the spare key.
- 🔋 Replace the battery in the remote control if the key has a remote control.
- 📡 Inspect the antenna around the ignition switch for damage.
⚠️ Attention: Do not try to disable the immobilizer by twisting the wires. This can lead to blocking of the engine ECU and complete starting failure even with a working starter.
The immobilizer is a common cause of startup failure if there are no other visible electrical problems. Always check the key first.
Self-repair algorithm
If you decide to fix the problem yourself, follow the sequence of actions so as not to waste time. Start with the simplest thing: checking the battery and terminals. It takes a minimum of time and does not require special tools. After making sure that the power supply is normal, proceed to checking the control circuits.
Next, check for voltage at the starter control wire. If there is voltage, but the starter does not turn, the problem is in the starter itself or its solenoid relay. If there is no voltage, look for an open circuit from the ignition switch or relay.
Removing the starter Nissan Almera Classic is not difficult, but requires access from below the car. It is advisable to carry out work on a lift or in a pit. Unscrew the two bolts securing the starter to the gearbox and disconnect the connectors and power wire.
After dismantling the starter, you can check it on a workbench. Connect two wires from the battery: one to the body (ground), the second to the power bolt. Connect the third short wire to the control contact. If the starter fires, the problem is in the wiring or the lockout relay.
How to check the starter without removing it?
It is sometimes possible to test the starter by applying power directly to the power bolt and control contact, but this requires caution and an assistant as the vehicle may start moving.
Repairing or replacing the starter is the final stage of diagnosis. If the starter cannot be restored, it must be replaced with a new one or a known-good used one. When installing a new starter, be sure to lubricate the Bendix gear with a special lubricant for starters.
After assembly and startup, check the operation of the starter in several cycles. Make sure that it does not make any unusual sounds and stops quickly after starting the engine. Normal operation of the starter is the key to reliable starting in any situation.
FAQ: Frequently asked questions
Why does the starter turn, but the engine does not start?
This could be due to a lack of fuel delivery, a faulty crankshaft sensor, or a problem with the fuel pump. The starter does its job, but the engine does not start for other reasons.
Is it possible to push start the Nissan Almera Classic if the starter does not work?
