voltage lost at fuel pump relay

ok so here is the problem i am trying to get my 1978 280z running and all the relays are good but i do not get any voltage to the actuation side of the furl pump relay. but if i jumper a 9 volt battery to that side of the relay i can get the car to run till the battery runs out the only exception is when its like that if i try to turn on my blinkers or hazardz then it dies and i also dont have any interior lights. or instrument panel lights. any ideas ???
