no voltage to fuel pump

'02 astro with all the bells and whistles. Was Idleing a while back and died. Wouldn't start. Having had an astro before, I checked for fuel pressure on the rail. Nothing. Swapped Fuel and AC relays, Nothing. Put a jumper directly to the output terminal of the fuel pump relay, nothing. OK, I must need a fuel pump.

Tonight, I finally sneak this thing onto a lift. Drop the tank, look at all the plugs, they look fine. Put power to the pump, it runs. Dang it. Check for power at the big plug going to the pump, nothing. Tried with the key on, Tried jumpering the relay. Still nothing. My schematic doesn't show anything between the pump and the relay, fuel quantitiy still works, what am I missing?
