my car has power but will not turn motor over !there is nothing when you turn the key to start . could it be a fuse?

 

I'd check the battery connections first. Make sure they're not loose or corroded. could be ignition switch, starter, starter solenoid, neutral safety switch, start relay (unlikely), bad connection. Do the dash lights come up in the start position and do you hear any clicks or anything when trying to start? Has there been any history to this problem, did this just happen all of a sudden? BWT those are sweet rigs. my older 170 has been great and yours is even better, especially the 350. these problems are rare.
