Stainless steel Price Pfister kitchen faucet with separate pump soap
dispenser. It just stopped pumping... any ideas what is causing it and how
to fix it? TIA, Laurie

Might be some dried soap blocking the check valve. Remove the pump and
soak it in water overnight. Then try operating the pump while it is
submerged in water.
