I have a 1990 buick skylark.2.5 liter eng. auto,A/C. I got a new plug from the buick dealer.A buddy installed it not thinking about it he got the wires crossed.All 3 wires on the new plug were gray.Not knowing that the fuel relay,fuel injector,an all that is included in that circuit.So now I have no power to the injector. I need to find out which of the 3 wires go to which of the 3 prongs on the oil sending unit plug.So THANKS FOR ANY HELP.Tommy
