The soap pump at the kitchen sink does not pump. It has been out of use with liquid soap in it.
@fawn, Bruce, Submerge the pump assy. in hot water as the soap in the tube and pump mechanism has probably become thick and clogging the pump. after about a 2 hours start pumping the pump while still submerged to unclog. Empty soap reservoir and add new fresh soap to dispenser, install pump and give it a try. May have to pump forcefully until the pump starts to draw the soap back up. If all else fails and actual pump mechanism is determined broken, consider replacing unit with a new one stocked at hardware and big box stores. Links below give more info on trouble shooting soap dispenser and 3rd link is just one site showing replacement sink soap dispensers. Good luck.
