My pump seems as though it's sucking tons of air, but the line from the pump to the skimmer is airtight. I used a bladder type pressure device to charge the line and waited for leaks. After about 30 sec. it shot the plug I had in the pump inlet out like a shotgun. Didn't see any leaks.
My pump motor basket is only about half full of water. Its sloshing it in there fast but can't keep up. I've stuck my fingers in all the holes and the impeller feels normal and clean. After I turn my pump on and back off there is so much pressure I can't even get the lid off the pump basket.
Lastly the filter is running at 0-4 lbs pressure. When I turn the valve to recirculate it does the exact same thing minus the filter pressure.

Is my pump trashed?
