Hi all. I have a query. My 2011 Nissan Juke has decided not to start. The electrics are all working and the radio comes on, but the engine doesn't even turn over. It had a new battery 3 months ago, a new cam belt and water pump. Our mechanic has tried all sorts, but can't find the fault. Is there an immobiliser of some sort that I don't know about?? Any ideas greatfully received! Thanks in advance.
