I have a 2007 tuson, the main relay is not energizing. I know the relay is good becouse I switched it with the starting relay, ( same part number) and the car will still turn over. If I jump out the contacts in the main relay the car will start and run. I think I have some kind of a grounding problem with the negitive wire on the relay coil. Does anyone have any advice before I start to pull wires..?
