Recently purchased 2013 Equinox, 118,000 miles. Parked it until the snow melted, ended up having to jumping it to move around garage. So replaced Battery, now when trying to start the Starter wheel spins freely and will not plunge into flywheel. Tried replacing Starter but did same thing, switched multiple fuses/ relays same result. At a loss of what to check next. Any help when be much appreciated.
