    Like Labrador Guy said, it has to be deeper in the water.  The pump is above those “horizontal holes” you mentioned.  It’s in the “bulge” and it will not self-prime.  You need that bulge that is a few inches above the cavitation plate submerged.  If you have run it for a couple minutes without doing that, you may have destroyed the pump impeller, so it won’t pump when you have the water the right depth.  New impellers are very available.
