My car was working fine when i got home, but when i tried to leave, 30 minutes later my car would start up, sound normal BUT just die out within 3 seconds. my car was a little low on Oil but i put in more, and even more gas because i was on Empty a little bit. but still the same thing. start up, SOUND NORMAL but then die out 3 seconds later. does anyone have any ideas or suggestions?? PLZ HELP :\
