I was given a 1979 ZX that is not running.. I tested the fuel pump and it was shorted out. I got another one, replaced the old one and now I have no voltage to the fuel pump. The fusible link was blown, so I replaced it. But still I have no voltage to the pump. I haver tried to trace the lines to it but can not see where the break is or the problem with it. I would appreciate any help anyone can offer.. I am stumped and am not sure where to go next. Thanks
