I had that problem after my Tracker sat in the garage for a week or two... went to start it up, got nothing but ticking... couldn't jump start it, more ticking, and no turning of the starter at all... I started messing with the wires, and found that if I wiggled the ground that went to the starter, it would turn over once or twice, then do the same thing. I fiddled with that stuff for a few minutes, then said fuck it, got a hammer and tapped the solinoid. Started right up... I'm hoping it's just the wires and not the solinoid going bad :-/
