ok, ran a jumper and the fuel pump does turn on, whether the key is on or off. probed all the connections and they are the same as mentioned above. as for the main relay, maybe that far left pink wire should be swapped with the bottom pink wire in the relay? im not too sure how its supposed to work, but the big red wire (top) has constant power, as does the pink wire opposite (bottom). the pink to the left only gets 12 volts with the key turned.

also, if i flip the relay over it goes likes this...
big red power wire (top) - 87
black ground - 85
left pink wire - 86
bottom pink wire - 30

do the diagrams look correct?
