Starters can fail just about anytime, although the solenoid is the usual culprit. A rebuild is about $30 at a good shop. You can remove it in the morning, drop it off for rebuild and have it back in time for an afternoon re-install. Are you sure it isn't the battery? You can go to an AutoZone, PepBoys or similar and they'll do a free diagnostic. If it's the battery get an Optima Red Top and worry no more! ;Dr;
