Possible electrical problems that prevent the machine from starting:
1. Discharged or faulty battery:
* The battery has a lifespan of several years and may become depleted or damaged over time.
*You can check the battery using a multimeter or by jumping from another car.
2. Defective starter:
* The starter is responsible for starting the engine.
* If it is faulty, the engine will not turn when the ignition key is turned.
*You can test the starter by connecting it directly to the battery.
3. Faulty starter relay:
* The starter relay supplies power to the starter.
* If the relay is faulty, it will not allow the starter to receive power.
*You can test the starter relay by knocking on it or replacing it with a new one.
4. Defective ignition switch:
* The ignition switch is responsible for starting the electrical circuit necessary to start the engine.
*If the lock is faulty, it may not transmit current.
* You can check the ignition switch by replacing it with a new one.
5. Damaged wires or terminals:
* Damaged wires or terminals may prevent current from flowing to the starter.
* Check wires and terminals for corrosion, cracks or breaks.
6. Faulty neutral switch:
* The neutral switch prevents the vehicle from starting if it is not in neutral.
* If the switch is faulty, it may not allow the engine to start.
*You can test the neutral switch by moving the car to different positions and trying to start it.
7. Problems with spark plugs or ignition module:
* The spark plugs or ignition module provide the spark needed to ignite the fuel in the cylinders.
* If they are faulty, the engine will not start.
* You can check the spark plugs or ignition module by replacing them with new ones.
8. Faulty fuel pump:
* The fuel pump supplies fuel to the engine.
* If it is faulty, the engine will not receive fuel and will not start.
*You can check the fuel pump by measuring the fuel pressure.
9. Defective electronic engine control unit (ECU):
* The ECU is responsible for controlling the various electrical systems of the vehicle.
*If the ECU is faulty, it may affect engine starting.
* Special diagnostic equipment is required to check the ECU.
10. Problems with the immobilizer:
* An immobilizer is an anti-theft system that prevents the engine from starting without a key.
* If there are problems with the immobilizer, this may result in the car not starting.
* Special equipment is required to identify problems with the immobilizer.
