1976 450 fuel pump new not working
I have 3 new fuel pumps for my 1976 450SEL. when i put power to the + and - side of the pump with a good 12v battery with good sturdy cables i get nothing. no click, no whirl...nothing.
i am wondering if perhaps i am doing something wrong. 3 new pumps not working???
can it be that they need fuel or need to be primed in order to work? any advice would be appreciated
