Pulsating is usually due to a leak. It could be the pump leaking or the hose, gun or wand leaking. Is there water coming out of these anywhere it is not meant to?
It could also be a valve is not closing properly or a seal needs replacing.

hello , yes i did check for some leaks but seems ok there . the pump did spray at full pressure for a second or two but only did this a couple of tims then goes back to pulsating . it sprays like it doesnt have enough water pressure but my water supply is just fine to the pump .
I took apart the 3 caps on the brass water supply unit on the pump and cleaned out the inner what looks like pistons and found a piece of debri in one of them not alowing the piston to close all the way , also found an o ring in the gun that was bad . works just great now . thanks for the help .
