You need answer some questions first to rule some things out.
Is the starter making a noise when you turn the key or is it just clicking? If the lights light, but the starter makes absolutely no noise, then the power cable to the starter is bad or contacts are corroded. If you hear a click every time you turn the key but that is all, then the starter is bad and needs replace. Once it is removed, most parts stores can test it for you. If you can hear the starter spinning but its going real fast then again the starter is bad. If the starter is working properly (like on a really cold day when it doesn't start right away) but the car still won't start, then the starter is fine and your problem is either in the ignition or the fuel system. You may be able to narrow it down if you can read the codes, otherwise it needs a mechanic and you need to decide what is the car worth to you.

I'm thinking its the battery. Heat kills batteries. You said it wont jump start. That's a dead ringer for a bad battery. It may have enough juice to power some things, but wont run the starter, or the fuel pump, or the ignition(spark). Try a new battery and let me know!

the clicking noise is most likely coming from the solenoid on the starter motor, the solenoid is like a big switch with contacts inside of it,when you turn the key to start the engine these contacts come together to transfer the power to the starter motor,if the solenoid can't be taken apart & the contacts cleaned or replaced it will have to be replaced.......hope this helps....cheers

Did you try jumping it?

I would start with cleaning the battery terminals ,teast battery & alt

Possible causes:
1. The STARTER is giving out.

2. The BATTERY is weak and doesn't have the cranking amps it needs.

A local autoparts store will normally test these two things for free.

starter motor! good place to start be creative tap it with hamer should start then replace starter!?

may have problem with selonoid on top of starter jamming give it a tap with hammer then try
