Starter?
I don't think its the opti but that'll probably soon 108K on the clock
Anyways. Check your battery out. Take it to an auto parts place that tests starters for free. If it checks out ok, then pull of the starter and take it to get tested. the starter is really easy to pull off so its not to bad or even a hassle.
If it still doesnt want to work, check the connections from the battery to the wires. Also I had the same problem with my TA, it was just the connector from the starter to the battery post. So the post was tight but a little thing coming off the side fed the battery and it was loose.
