as far as your car not wanting to start it could also be your idle air control (IAC) valve. it sits off from your throttle body.

i've had to have mine replaced as well as many other people. when i had the problem, i would turn the ignition, the car would start, but it would stay on, it was like it was being choked out. the car would stay running if i kept the gas pedal down, but as soon as i let go, it would stop running. this was happening randomly for a few months until it just wouldn't ever crank up.
