there is a loader and unloader valve on your pump bolted to it. if it frozen in the open position it will never build press. most of the time this is caused by leaving cleaning solutions in system after use and let set up for a long period. it causes the aluminum case to corrode.;you will have to dissassemble and clean if not to bad. if not your going to have to replace.

You asked what the trick is. Well it is a trick, and in fact a big hasle. When a pump has failed it is never removed from the engine or from rhe electric motor(if electric motor driven.). To service the pump only the head and its components must be removed. When these are removed and the oil drained, you see a swash plate that is held down by a bolt. The swah plate could also be fitted by force fitting. After the swash plate there is an oil seal then a bearing. So if for a reason you must remove the pump from the engine you must do all these steps. In a few words....Remove head, remove piston holding head, drain oil, remove swash plate and finally the pump can be pulled away, but with some force,..because there are bearings. I wish to repeat that if the engine has no trouble, do not remove pump from engine. Just service or replace parts of the head of the pump.

SOURCE: engine keeps shutting down
Most Honda engines have an oil pressure switch that prevents engine damage due to low/no oil pressure. Make sure there is sufficient oil in the engine and that the wire is connected to the pressure switch.
