Since the skimmer and pump baskets are clean and you do have reduced flow my next guess would be a gunked up impeller. You mentioned doghair so I also assume you have to deal with a hair issue before. This stuff could easily get tangled in the impeller. Kill power to make sure the pump cannot come on accidentally, remove the pump basket and reach in the hole to the pump. If you feel hairs or stuff in there you can use a stiff hooked wire to clean it out. Since your pressure is zero that rules out a problem on the pressure side so we look to the suction side. If the suction line from the skimmer is clear, baskets are clear, no air leaks, then the only thing left is that impeller. Let's see what you find.
Hope this helps.

Poconos you were 100% right whoa. Argh! I removed the plumbing from the pool to the strainer to reinstall with new PVC. Just because you mentioned it I checked the input hole to the pump impeller VIOLA! It was gunked up with dog hair bamboo shoots and DE. I removed the 6 bolts on the Hayward super II pump and cleaned all inlets how you can do that without removing it I donno as the inlets move diagonally and I did use a wire hanger. The 6 bolts are nothing to remove and you get everything clean that way. Anyway glued up the PVC fixed the pump back to the strainer. Followed the bleeding the air before the DE input advice then I noticed jacuzzi output on my pool jets from zero psi to 20 in one fix. Now things circulate the pool in less than a minute crazy wave action. My water turnover is very fast now. I probably would never have checked the impellers although I did this once before about 8 years ago. I just would not have thought of it but you were right so thanks for saving my sanity. If you have zero pump pressure CHECK THE PUMP IMPELLER before checking the plumbing. After you check the obvious baskets. Next step for me was to break down the brand new hayward pro filter to clean the grids and I wasnt looking forward to that just yet. WEEEE thanks again!
