I was driving down my hill to a 3 way and put on the breaks to stop and turn then my car died, i put it in park and tried to turn it over, the engine sounds like it normally does when i go to try and turn it over, but it wont start, my gas pedal feels really loose, unlike before when i need to put a little gas on it i can feel it pump, or it is more stiff, what do you guys/gals think my problem is?
