Ok I got a new relay from the autowreckers and it does the same thing. anyone have any ideas?

ok so i bought another relay and a resistor and i still get the buzzing when i connect the battery. Does anybody have any clue what so ever??? I am dying over here

i checked the resistance and it all checks out as per what the repair manual says. so it must be something else doing it?? i tried searching the forums and cant find any answers. I am on my knee's begging someone has to know the answer

thanks Jeff

For some reason whenever i jumper the fuel pump in the diagnostic box, my relay buzzes, but when i run the car it does not. Im not sure why, but maybe it can help you figure out your problem.

I have a 88 non turbo too, does yours crank up. Mine buzzes but cranks, as long as it cranks its is fine with me.
