My Question would be why does the car all of a sudden not start?

test battery 1st and then pwr to starter, it could be several issues.poss rec having it ck' by your mech and save time and money

Bite the bullet, remove the starter, bench test it. Chances are that is your problem.

As already stated , test and be sure the battery is fully charged. The next easy step for you to do without any dis-assembly is to turn the headlights on (prefferably when dark)and watch the reaction of both the headlights and dash warning lights while you try to crank it (and it presumably makes the 'clicking' sound.If everything goes COMPLETELY dead , you have a bad connection.If it just flickers when it clicks then I'd agree---remove and have bench tested and while your therebefore removing the starter check the signal wires connection to solenoid -could have same symptom if that is loose or faulty.
