My nissan micra 1.2 auto 53 plate doesnt start.. put the key in, turn to ignition, all lights come on, nats indicator light goes off after a short solid red, turn key to start and then nothing. It doesnt crank and no light dims. Play around with it for a while and then it starts!. Seems to continue working once you can get it started but park it for a few hours and then it is same story. But it seems to be getting worse now. Any ideas please?. Many thanks
