You've probably bent one of the tabs that hold the fag lighter in its slot and it's got no -ve return. Usually, it also means if the lighter does get hot, it pings out & sets fire to you/the back seat.
Bend the tabs back in with a screwdriver.
Failing that, check the pin in the base is hot, with a cheap multimeter. It may be covered in c rap or something. Or the 10A has blown.
The return lead could have fallen off the casing, as suggested above.
Merlin - I'm fed up of that happening. I now turn off the radio first and start the pump before connecting it to the tyre valve!
