immobilisers are a common fault on all renaults up to 2003 when they introduced the key card. the fault that you have listed are for the code ring which is around the ignition barrel. this reads the code from the key and tells the ecu that it is allowed to let the car start. this could be causing the ecu not to inject fuel or send power to the coil packs. had the same problem with my megane. but my immobiliser light stayed on constant until the ignition was turned on then it flashed. i got a 4 digit code from renault to start the car. this code will only work if your immobiliser light flashes when the igniton is on as you have to count the flashes then turn the ignition off for each number in the code.
