I have 'done something' to confuse my car! I was sitting with ignition in position 2 - to have fan on - for about 10 mins. When I went to start car I neglected to turn key back to zero, went straight to starting. Nothing happened. Sounded a bit as if battery had run down. Long story short, an hour and a half later she started as normal. Thought it was just a glitch, but today this happened again, even though I had done nothing stupid. Wouldn't restart, but did after waiting 1 hour+. Any ideas? Don't have money for lenghthy diagnostic!
