next time you start it...if it doesn't....jump the selonoid first..
turn the key on and use a screwdriver to join the pos batt terminal to the one w/ the little red/blue wire on it. (right on top)
you'll get a couple sparks...but it will start the car. if not it's the starter itself...have someone turn the key like they are starting it...and rap the starter w/ a hammer..if that starts it, it's the starter for sure, but it's one of the 2
