That's all, first time it's failed on me.
Will call the cavalry in the morning.
Well, you posted this yesterday so your car is probably fixed now, but mine wouldn't start on Friday evening, left me stranded at a petrol station!!
It was turning over, the immobiliser light had gone out, so it wasn't that, but it just wouldn't start.
Called AA man, he got it started in about 2 minutes. Turns out my CRANK SENSOR was covered in metallic dust and buggered it up. Give it a quick clean and then... car starts instantly first time.
