do you have the 'P' code that should have preceded the fault message about the sensor reference?

As I suspect the issue is with the crank speed sensor as that will prevent the engine starting

if the sensor is OK then check over the wiring and connection for damage

Your conclusion to check or change the speed sensor has not resolved my problem, I will explain in full detail what is happening , when key card is inserted and start button pressed engine does not turn over. injector fault comes up on dash. as previously i sent you fault code. I changed high pressure pump fuel pressure regulator this vibrate and buzzes.after i tried to start it i also changed fuel rail pressure switch, also changed speed crankshaft sensor.they is also a buzzing noise being omitted from the EGR sensor. I have fuel upto the pump fuel rail and injectors. the only way i can turn the engine over is to connect a wire to the solenoid and connect it to the battery then the engine will turn over. but will not start or eliminate the fault.

thanks for the extra information

if it won't crank / turn over then its likely to be a security system issue

sorry to say that due to nature of the system they aren't DIY fixable and the only route forward is to get the car to a dealer or Renault specialist who will carry the correct diagnostic kit to re-programme the key card and reset the immobilser
