It was occasionally not starting, only a click. Then would start for a while. Charged the battery, still happening at times. 12.57V off, 14.5V running, so alternator good. Had tested the starter solenoid on the firewall a while back was ok. Got stranded the other day. Tried hitting the starter and solenoid. Nothing. Tried to jump nothing. Replaced the starter solenoid anyways, nothing. Jumped it again, and it started. Got it home. Wouldn't start for a day. Went out today and got it started, and got it in the garage. Should I just go ahead and replace the starter? I never really heard the starter click or engage, but the starter solenoid on the firewall was clicking.

 

Check and clean the battery connections at both ends. When it doesn't start maybe whack the starter to see if that affects it.

 

Rainy day here, so went and changed the starter. Seems to have fixed the problem. Thanks for the help.

 

The old starter had worn brushes that hung up off the commutator from being to short.
