If fluid was neglected it could be the valve block too. Little bits of cylinder seal rubber can find its way to places it shouldn't be.
Can you put a hand on pump while running it? I'd further test by taking pump reservoir cap off and hold above opening while someone operated switch. It should be returning oil to reservoir. Careful it could be messy, but return is low pressure. Pump has a relay as well.
First things first....confirm motor pump runs. If not it's electrical.
