ok this morning i started her up and it took 5 seconds to get her on and she was idling fine but i turned her off 3min later and then started her up do to i was waiting for my friend to come out so i turned the key and nothing.no lights ect.I thought the battery was dead so i jumped her and their was nothing.I checked the fusses under the steering wheel and they seem to look ok and then i checked the fusses under the hood and they were ok.could it maybe a bad battery??
