If there is live feed on central heating pump...?

but the pump isn't kicking in, what does it mean?
we have installed a pump, live feed has been detected in the wires so it should be ok, but it's not kicking in. Have turned on the thermostat and the main control switch but it's still not making any noise. Could the pump be naffed? Can the pump be tested by wiring it into a normal plug and plugging it in to test?
