Has My Pump gone out?!?!?

what psi is it?
do you have a pressure gauge on the unit? f so, what does it say?
Did u let it freeze? that would be bad.

is there air in the line? It may need to be primed first if air got in the lines somehow.

does it have inline filters on the wand or unit? if so clean them.

With my other business I work a lot with high pressure pumps and pressure washer pumps. In fact I notice some of the truck mounts and portables use the same pumps that I'm used to working with, especially Cat and Hyrpo pumps.

Like FuzzSucker said, it could be air in the pump or line. Although if this were the case I'm not sure why you would get some water out of the wand. If you didn't prime your pump before using it, you probably had air running through the pump. Running just air through the pump is not good because you can damage it really easily, especially the seals. Even if you prime the pump before use, you have to be careful that you don't run air though the pump when your solution tank gets low/empty. That's easy to do if your not paying attention when your cleaning and you don't notice that the wand is just spraying air.

If there was any residual water left in the pump after use and you stored it in a cold area, there is a chance the water could have froze and damaged the pump. That actually happened to my pressure washer a few weeks ago and now I'm replacing the pump
