Meant to say no heating downstairs, heating ok upstairs. Pump used to be understairs in hall where thermostat is. Thats about 15ft from my back boiler. Looked underfloor boards understairs cant see it. Some people have told me that I may not have one. Sorry for the misunderstanding. Thanks for getting back.

The other option is to follow the wires from the timer which should be on the chimney breast

If you've still got back boiler and can't find pump, I would suggest two places: either at the side of he chimney breast where the back boiler is, or alternatively, under the floor boards in an upsatirs room.

Can't find central heating pump no heating upstairs?
