I have no power at they grey pump wire, purple runs gauge(works), the 3 other wires to a plug on the pump have no power, I checked the relays and I have no power there on the one but the other 2 are good, and no power to the 6 prong plug on the ECM in the engine bay. Normally when I see a big red wire it means power, but is this where my problem begins or does it go deeper? any advice...
