Message So I have narrowed down my issue to either one of the 2. I have tried a new relay with no luck. It does not click hence why the fuel pump doesn't prime. I have jumped the ground and power at the fuel pump relay female side and fuel pump comes on. i have power at the female side of the connector on 2 of the pins and ground on one. The last one I don't have power or ground which is a black/white cable which I think is my problem. I have no codes except 34. I have Tryed to bypass the fpcu which the splice trick and connect is straight to ground but no luck. Where does that black/white wire come from or go to? Any other ideas thanks
