I had this happen in France bought a tin of WD40 then eventually found the problem.
What it turned out to be ......I was faffing about with a pay pump by the time I'd sorted it the petrol cap had timed out after 2 mins so turning ignition on didn't do anything as it wont open with it on but turn it off and open within 2 minutes it'll be fine
