Well, in the process of getting ready to sell my boat, I mistakenly hooked up some jumper cables from my boat to my truck....reverse polarity, and tried to start the boat before I realized my mistake. Now I get a click. Engine will not turn over, and no noise from fuel pump. Doing a little research, this may look to be a costly mistake. Figured I would ask here for some possible troubleshooting tips, to narrow down where the problem/problems may be. Family code for engine is 7M9XM05.0GME Any help is appreciated!! Thanks.
