Why won't my car start?

I would replace the ground to the battery , they are known for corroding internally , it will cause same issues but will not do it all the time, that's where I would start , good luck hope this helps

Did u ever find out what it was?because mine is now doing the same thing

Mine also. I have a 1999 Dodge Stratus that everything comes on and works but motor won't turn over and start?

Try your windshield wipers, if they do not work with the key on, your problem could be as simple as a blown fuse. I had this same issue and replaced fuse 20, and it started right up! Try this before spending more money or replacing parts.

People check either the range sensor/ neutral safety switch. Should be on the transmission on drivers side I believe. Or the Inertia Switch which is designed to cut off fuel in a fender bender. They sometimes just quit completely...or the button on them needs to be pressed. Mine just quit..pressing reset did nothing so I unplugged it and put a short wire into both pin in connections on plug bypassing the switch. Started right up.. One of these I believe Inertia car will crank n crank but not start cause fuel flow is cut off. Neutral safety on the other hand usually when you turn key all dash lights come on normal if doors open dinging works etc. Radio too but when you turn car to start position you get NOTHING no click no turn over. Nada nothing I know as cars get more and more technical I may be waaay off. But If I turn my key and get lights etc and not click or anything the neutral safety would be what I'd first check if I suddenly just crank I check the Inertia first. Cause it easy and usually located on passenger side kick panel or in the trunk. If that's not it it's on to check for fire and fuel...blown relays fuses or failing grounds
