your alternator is dead.
This happened to my 04 neon. I had to replace the sparks plugs and the thermostat.
Check your timing belt , and your fuel pump inertia switch ! Good Luck !
its not your timing belt you need a alternator belt,but have your battery charged before you drive the car,you could damage the computer with low voltage
Are the lights in the dash coming on, and it just won't crank or are there no lights at all? If the lights are coming on you need an ignition switch.
could be fuel filter
Check for poor ground connection either at the alternator or follow the negative cable coming from the battery.
=I don't know about the brake lights. I know that most cars, when you turn it off and get out, the head lights and main backlights stays on for a while but then goes off. The brake lights? Maybe it's the way that car is or something is wrong with the brake or you have it on wrong.=
IDK yup
if its a stick shift and ur shifting it wrong then mabye that's why
Check wiring harnesses - prone to corrosion
Start with changing the fuel filter.
Your alternator is not keeping the battery charged.
