Ok I just bought this car yesterday, and everything was fine...just now, being about 9:40pm I go outside to start the car so I can pick up my gf from work, and behold the starter is working fine, but the car wont start up....I hear the usually sound of the starter before the engine fires up, but its not starting!!!! I have to manually put the key back into the position before starting it to make it trying to keep starting by itself!!!!

I've searched and have not found any answers...SOMEONE PLEASE HELP!!!!
