My flojet pump runs but it pumps no water . It is a 25 gallon sprayer

Sounds to me like it just needs priming (or in other words) the air bled out of it.
Using the force of gravity, force water to run STRAIGHT DOWN from the 25 gal tank, through the gate valve & into the running pump.
While doing this, close the bypass valve slowly until it's about 3/4 of the way shut.
You should begin to hear the sound of the pump begin to deepen as the air escapes.
If you don't, then there may be an air leak somewhere along the hose line, typically at the filter, causing it not to prime.
Correct the air leak, then you'll probably have better luck.

I recommend not running an electric pump like a Flojet for very long when it's not primed. Doing this may overheat it & shorten its lifespan considerably.
