I was driving home the other night, put my foot down going up a hill, my car stalled and the 'N' light started flashing. I managed to get off the road but my car wouldnt start again, when I try to start the car the AYC light stays on and the car turns over but wont fire.

Was worried it was the cam belt snapping but a subsequent check at the garage proves it wasn't this. I am having a diagnostic test on thurs, but has anybody any ideas on this one??
