    not sure about the spark or what car its in but since its a 304 i am guessing its a commy motor with efi, which would still give the fuel pump power while cranking even if the fuel pump relay is pulled once oil pressure is built up(i am not a wireing guru but i know power is somehow fed from the oil sender to the fuel pump as a back up once oil pressure is built up)
    heres my ride, i know its not much but its mine
