Gas pressure washer

My unit starts up fine; cleaned out the filter and hose, got a new spray nozzle and fittings, changed the oil, but when Icrank up the unit it will not produce any high pressure. When I pull the nozzle trigger a very low pressure comes out of it, and when I say low I mean low. I have no idea what is wrong. Please help.
