Possible reasons why the car does not start when the electrics are running:

* Clogged fuel filter
* Faulty fuel pump
* Problems with fuel supply to the engine
2. Problems with the ignition system:
* Faulty spark plugs
* Failure in the ignition module
* Problems with ignition coils
* Worn ignition wires
3. Problems with the starter:
* Starter malfunction

* Reduced battery charge
4. Problems with the immobilizer:

5. Mechanical problems:

Recommendations for diagnosing and troubleshooting:
* Check the fuel level: Look into the fuel tank and make sure there is fuel in it.
* Check the battery: Make sure the battery is charged and the terminals are not loose.
* Listen to the starter: Turn the ignition key to the “Start” position. If you hear a clicking sound but the engine does not turn over, the starter may be faulty.
* Check for spark: Remove the spark plug and bring it to the engine body. Turn the ignition key to the “Start” position. A spark should be visible.
* Read vehicle trouble codes: If your car has an on-board computer, connect an OBD2 scanner and read the trouble codes. This may help determine the exact cause of the problem.
If you cannot determine the cause yourself, it is recommended that you contact a mechanic for professional diagnosis and repair.
