my fuel pump is new and was working fine when i last ran it a few months ago...now the fuel pump doesnt kick on and the wires have no voltage reading. ive checked the green fuel injection relay by the battery and its working, and ive swapped out the blue one in the passenger door frame vent with one from under the hood...still no power to it. so my main question requires someone who knows z31s better than me; what else could be wron?and would i be better off just routing new wires with a new relay from fuse box to fuel pump? thx
