make sure your battery is charged, check the battery cable connections, get your starter and alternator checked, then ask a mechanic. then push it off a cliff and buy a new one
if you have to cars use thebattery from the car that works and use that for the car that doesn't work
If you have some power for other accessories, try a jump start & then check alternator when you get it going.
