I rigged a fuel pump to work in my car, resoldered the main relay after i was getting a CEL during cranking, solved the cranking issue, i tried to run the real fuel pump and it still isn't getting power. I wired a positive to it, no power, wired a negative to it with the stock positive wired up, still no power, wired directly to it positive and negative, i have power. What the f uck...? I have a bad signal and a bad ground...any ideas?
