I have an 07 sportster 1200 custom with a short or loose connection somewhere powering the fuel pump(efi). While sitting on the bike i reach under the tank and figit around and it will turn on so im trying to find a short. I removed the seat and played with the ecm but the connection is here and there just in time for the season damnit! Is this a common problem, what am i missing? At worst would anybody have a wiring diagram to see what wires are powering the fuel pump, start to end, so i can start checking resistance? Please help, im itching to get out!!
Thanks a lot
