Pretty sure my pump is just screwed.

Ok, so the car has spark. I've measured a 12v at the fuel pump connector on
the red/blue wire for ~2 seconds when the key is turned on and constant when
cranking.  Constant ground on the solid black wire and the black and red
wire.  Brown/black show open when the key is on and measure ~50ohms when the
key is off; I guess this is a relay somewhere.  I don't have a schematic on
hand.  

Gut says bad fuel pump. It doesn't cycle when the key is turned on and it
seems to be getting power. Tapping it does nothing.  Any thoughts?

If anyone has a schematic, that'd be helpful as well.
