This is an astonishingly common problem. Sometimes it's just the result of pure carelessness and forgetting to check the fuel gauge. Other times it's because the fuel gauge itself is faulty and
was reading full when it was actually empty. Alternatively there could be a fuel leak.
How to avoid it
If you suspect that the fuel gauge is playing up, or that you've
got a leak of any description, get it checked out by a garage as
soon as possible. And don't procrastinate when it comes to filling
up.
What to do if it happens to you
If you suspect a fuel leak then you should be able to smell
the petrol or diesel. Don't even think of trying to start the
car under these circumstances - call the breakdown service
for help.
Don't keep attempting to start the engine in the hope of
squeezing the last drops of fuel out as this can suck air and dirt
into the fuel system and make things even worse.
If you've got a can of fuel with you or can get one from a
nearby petrol station then switch off the ignition, empty it into
the tank and drive to the nearest garage to fill up properly.
If you're stuck on the hard shoulder or a long way from the
nearest petrol station then your best bet is to call your breakdown
service.
