This brings back memories to my first ever car(Vauxhall Viva), I was seeing a girl in Chelmsford and the traffic was often bad, if it was queued back further than a certain point I knew I was in trouble, the car would stop and not restart for at least an hour or more, despite numerous AA callouts the problem was never solved. One day I was going to work, I reached the dreadful Canningtown roundabout and sat in traffic, as I finally pulled on to the roundabout it cutout on me and wouldn't start, I lifted the bonnet and for some unknown reason I decided to put a radiator bracket I had in the car between the head and the petrol pipe, problem solved, it never did it again, it was obviously the heat from the engine evaporating the fuel in traffic. The hours of pain that had caused me! On another note, when I filled my 7 up for the second time, as I took the cap off there was a big suction of air, does this mean I have a problem with the tank or cap? Alan
