Possible reasons why the car will not start due to electrical problems:
1. Discharged or faulty battery
* Check the lights (headlights, turn signals) – if they are dim or do not work, the battery is most likely low.
* Check battery terminals for corrosion or looseness.
* Replace or recharge the battery.
2. Faulty starter
* When you turn the key, you hear a clicking sound, but the engine does not start.
* Check the starter connections and make sure they are clean and tight.
* Replace or repair the starter.
3. Faulty engine control unit (ECU)
* The ECU controls all electrical and mechanical systems of the engine.
* Check fault codes using OBD2 scanner.
* Replace or repair the ECU if necessary.
4. Wiring problems
* Inspect the wires under the hood and in the interior for signs of damage or chafing.
* Fix any obvious wiring problems and replace damaged wires.
5. Malfunction of the ignition switch
* Check that the key turns smoothly and completely to the “Start” position.
* Replace the ignition switch if it is faulty.
6. Faulty generator
* The generator charges the battery and provides power to the vehicle.
* Check the generator voltage using a voltmeter or OBD2 scanner.
* Replace or repair the generator if necessary.
7. Other electrical problems
* Faulty ignition distributor
* Faulty ignition coil
* Faulty spark plugs
* Faulty ignition control module
Troubleshooting steps:
* Check battery and starter.
