K i have these issues with my car starting i thought it was the starter but i dont think it is. Last year when i drove it i'd go to a friends house and the car wouldn't crank over so i waited try pushing it and pop it into gear still wouldn't crank. Waited longer then it started. My battery is good grounds are in place i event knocked on the starter and still don't crank I had a spare one put that in still no cranking. When i took my old one out i knocked on it some more put it back in still won't start not even one turnover just clicking. Anyone know what's up? I've been having these issues a few times where once the car did start i would drive somwhere then turn it off and be gone for a bit then come back and the car doesn't want to start.

 

main relay? checked your grounds/connection? i had a similar issue in my integra before

 

I just had a similar issue with my R when starting it up for the spring. I put in a new optima and had to twist my ground wire around to hook up. It would have power at 'on' position, but starting it, it would be dead. Found that I had accidently unscrewed my ground and wasn't grounding when starting. haha... may not help, but oh well.
