I'm working on a pressure washer the first one I have ever worked on. the pump seems to be pump water but no water comes out the nozzle.

Do you have sufficient water pressure to run the pump. I had to ad a 30 gallon tank to keep one running off my well.

I brought mine out of storage about a month ago and it wouldn't produce any pressure.  In fact I hardly got any water out the nozzle.  I took it apart and found the inlet clogged with debri.  Looked like something was making a nest in there.  Cleaned it all out and it works just fine now.

i'd look for a clogged nozzle or hose. If they had it all apart for winter storage, bugs will use that hose to their advantage!

Take the hose off and blow it out if that doesn't clear it up then it may have a problem with the check valves.The check valves are made of plastic and often will break or the O-Rings will go hard and not seal.

 

Most of the smaller pressure washers use the same check valves and are replaceable but they do Loctite the crap out of everything which makes it a real pain in the butt to take them apart.Some times they put to much Loctite and it ends up flaking off and getting stuck in the valves.Which causes them to not fully seal.

 

 

I have 2 DeVilbiss /Excell pressure washers in the shed that I have to tear into pretty soon.1 froze and 1 leaked.Both have the same pump.As far as I can tell neither one is cracked so I'm betting the check valves and O-Rings are bad.I bought both of these for the engines a few months ago at a yard sale for $20 each.1 has a 5hp Briggs Quantum and the other has a 5.5hp OHV Honda and they both run really good.To bad the crankshafts are so darn short I would love to put the Honda on my old push mower.

Looks like you are missing the tip...without a tip on the wand, you won't get a high pressure stream.
