...a new battery? sometimes it will make a sound as if it wants to start but just wont turn over. I also can let it sit for about an hour and it will turn over. sometimes it wont let start when I park it on a hill. On some days I get lucky and can drive all day and have no problems starting it and then go home towards night time and it wont start! pls someone help and give me ideas on what could be the problem thanks
