It does sound like a bad pump.
Remove the pump and disassemble it and look for obvious wear. If you do find excessive wear, best to replace the pump assembly. If worn internally, it is not rebuildable, all you can do to the pump is reseal it.
If pump has little wear and the internal seals are damaged, then reseal the pump.
