I have DTC but he said always EGR fault and i clean fault.But when i drove car to my mechanics his pro DTC said immo line open circuit or short circuit to ground.When i try to start the car when he refuse to start RPM on the dash stays to zero.Immo light operating normally.Car start always when its cold and strat always when its hot,only refuse when cool down on some minimum temperature antifreeze.Car never cuts while driving i change new crank sensor original Renault becouse i believed thats problem,wiring from him to Ecu but nothing,two years the same.Thanks

Hi, change the relay of injection and fuel pump. Also check the wiring to the fuel pump.
