machine =6.5 Honda Cat engine,with a 2SFX 30GZ pump Unfortunately I lent out my machine to a friend in fall of 2009.I went to use the washer last week,the motor started fine,ran water thru intake and output hoses and powerwasher unit,attached the wand after water circulated thru the sysem there as no presuere at the wand tip.I asked the previous user of the machine and he said it worked fine before he returned it.(believeable).What should I be looking at as the primary problem? and what would be the cost.I looked at replaceing the pump and at the price I could buy a new machine.Thanks
