Richard,

The first thought that comes to mind is a stuck check valve in the pump.  Have
you tried pumping from a bucket in the driveway?  Holding a thumb over the pump
discharge ( best done in warm weather and old clothes, GRIN) if there is
alternating pressure and suction then the discharge valve needs a closer look, if
no pressure at all I'd look at the intake valve.  Putting your thumb over that
one you should feel a definite pulsating suction.

YMMV,
Matt
