Does not start

    It starts only with an additional RC circuit at the input of the crankshaft sensor.  From what you can see, interference from the starter spoils the crankshaft signal.  As you put the filter, the interference is killed, but the ECU of the motor is not correctly determined and naturally the engine works with vibrations.  
    I have already changed 3 different sensors, the problem remains.  
    Everything is ok with wiring.  
    Maybe someone has an idea what it might be?

    Is the ignition system OK? Do you have automatic transmission? 
    Surely, firstly, it is better to look at the DPKV ( the camshaft position sensor) signal with  oscilloscope.
