the pump must not have any air leaks in the suction side of it,, or it will just **** air and not water,,, water is very heavy you see, however i think its the impeller in the pump thats the problem,,,you should try to put water in the out let of the pump so you fill the pump with water first if its dryed out it may just wear out the impeller before it starts to **** water up, if this still dont work turn off the stop **** and strip out the pump to look at the impeller any wear on it and it will need a new one fitted
i hope this has help you, good luck

SOURCE: Need to replace pump Impeller on A.O. Smith
To get to the Impeller you need to remove a series of bolts, or a large clamp, that holds the two halves of the pump together. Once you do that, if their is a diffuser (housing that goes over the impeller), remove it. To remove the impeller, you need to lock the motor shaft. You can do this a couple different ways depending on the motor. There will either be a small cap that grants access to the motor shaft on the back of the motor, or you remove a larger housing that grants access to the wiring and other components in the back of the motor. If it's the small cap, then you can hold the shaft with a wrench. If it's the larger housing, then you can slip a wrench (probably 7/16") under the thermal overload switch and onto the shaft to lock it in place. Now you can unscrew the impeller. Check to see if the impeller has a screw in the center. If so remove this first. It will be reverse thread. The impeller should spin off counter clockwise. If the impeller is very tight, be careful not to damage it. If you don't have an impeller wrench, I strap wrench, or very large locking pliers with a rag around the impeller works well. Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave a good thumb rating if you found this helpful. Thanks, and good Luck!
