i can't relay switch - what's going on?

this relay i'm using. have wired 5v rail on gpio, should fine according these specs. it's switching pump takes 600 ma @ 115v a/c - again, within these specs. when run 3v3 through input pin, though, led comes on nothing happens. swapped wires no nc , pump runs still doesn't switch.

i'm not of electrician, i've double , triple checked wiring , far can tell, plugged in ought be. missing?

if reading specs right, wants 85ma drive relay.

gpio pins limited 15 ma.
