Okay, so I went out to start the car only to find that it wouldn't start. it sounded like it was really trying but never did totally start. thats okay though because it was found to turn over last night so it wasn't the starter... or so i thought. today i have someone go back out and look at it and now it isn't turning over(i have no idea i'm not a car person). they tried to jump the car just in case and put in some gas as well. what is wrong with my car
