can any one help. I have just bought a 1999 megane 1600 16v. the vehicle started fine, i left it running until the engine was hot and turned it off. I went to start it a few mins later. all the ignition lights come on but the vehicle wouldnt turn over, not even a click on the starter motor. I tried locking and unlocking the vehicle in case imobiliser issue and still no change. I left the vehicle a few hours, came back to it and it started straight away. any help or guidance appreciated. the vehicle has done this twice now.
