Are you sure you got it primed okay? Seriously, those pumps are a b*tch to get primed! (I've wasted many long sleepless nights trying to prime those pumps!)
Remember it takes only a tiny little air leak and it will lose its prime. Best method I've found to prime those pumps is to fill the pressure tank with water and cycle the pump repeatedly (say, 40 times or so.) You can tell by the sound when it's pumping air instead of water, so shut it off then. In most cases the pump will be at the highest point in the plumbing for the well, so the air bubbles will find the pump and lose the prime. This is when shutting the pump off allows water to back-flush from the pressure tank, re-priming the pump. When the water quits "wooshing", turn the pump on again. Repeat until it works. (If you fill the pressure tank first and have everything else all plumbed up, then cycling the pump is just a matter of pulling up on the flat lever near the bottom of the pressure switch.)
How far is the well from the pump? It's amazing how much water that piping will hold!
You had the pump off the source lines. Black plastic? I could never get a perfect seal again on that pipe, I had to shorten it by about 2-3 inches (how far the nipple stuck into the pipe.) Even 3 hoseclamps won't squeeze it tight enough.
