Well Yesterday i had Pep Boys replace and alternator for me, and it drove perfect after that... Now today i go to the gas station, and then try and turn the car on and all of a sudden i just hear a click. Nothing else.. so the only way i can start it is by pop starting it... sometimes it will start when i turn the key....Its weird, what is the problem...TIA for the help

 

I had the same problem: sometimes it will start just fine but there are times when I would start it and it would just make a single click. Check your starter and your battery first. If you can, borrow someones battery and use it and see if it works ok, if not, when your car makes that clicking noise, try hitting your starter with a screwdriver to see if it starts afterwards. It can also be something with your grounding or your ignition. Let me know if it is your starter, I have one on the side that I have if your interested.
