[QUOTE="Duster, post: 446228, member: 20812"] If the battery needs to be replaced, do that. That eliminates the possibility that you accidentally finished killing it. You need enough cold cranking amperage. After that you know you have good power. So from there, you start checking continuity. The power for the starter runs from the battery, through a relay to the key and then back to the relay and then to the starter solenoid. There may be a fuse somewhere along there (been a long time since I did this last). Also check what the battery is putting out, and the what is being delivered with the key turned to start (you'll need help or really good eyes). It should be battery voltage at the starter. If all the wiring checks out, that is power to the relay, and power from there to the starter, then the starter itself is probably the problem. That can happen too. Oh - and if you have an automatic transmission, there is a second switch that permits you to send power to that starter only when the transmission is in park or? [/QUOTE]
