Possible reasons why the car does not start, although the electrics work:
1. Ignition system malfunctions:
* Faulty spark plugs
* Faulty ignition module
* Faulty crankshaft position sensor
*Faulty camshaft position sensor
2. Malfunctions of the fuel supply system:
* Clogged fuel filter
* Faulty fuel pump
* Faulty injectors
* Faulty fuel pressure regulator
3. Malfunctions of the engine control system:
* Faulty engine control unit (ECU)
* Faulty sensors (mass air flow sensor, oxygen sensor, etc.)
* Faulty wired connection
4. Mechanical faults:
*Low compression in cylinders
* Worn piston rings or valves
* Faulty starter
* Faulty clutch
5. Other possible reasons:
*Dead battery
* Poor contacts at battery terminals
* Faulty immobilizer
What to do next:
1. Check the battery: Make sure the battery is charged and the terminals are secure.
2. Check the ignition system: Remove and inspect the spark plugs for carbon deposits or damage. Check the spark by applying voltage to the spark plugs.
3. Check the fuel supply system: Measure the fuel pressure in the fuel line. Check the operation of the fuel pump and replace the fuel filter if necessary.
4. Check the engine management system: Check the engine trouble codes using an OBD2 scanner. Check the sensor readings and make sure there are no faults in the wiring.
5. Seek Professional Help: If you cannot determine the cause of the problem yourself, contact a qualified mechanic for diagnosis and repair.
