Chrysler Repair: 97 sebring v6 wont start after changing spark plugs, changing spark plugs, pep boys

Question
I hope you can help me.  I have a 97 Seebring with 80,000 miles.  Last week the check engine light came on and I brought it to Auto Zone.  They checked the cars computer and told me it was misfiring- they suggested I change the Spark plugs- so I did.  Now the car doesn't start.  I brought it to Pep Boys - they kept it for a week and then said they didn't know what was wrongs with it- I am in Espanola NM and I have a full car and a dog with me- I live in NYC.  How do I get this fixed? btw - after changing the plugs the check engine light went off and the computer cleared- but the car doesn't turn over.  Please help.

Stuck in NM

Answer
the only thing I can say is go back and recheck all your work to what U did.  This is not a part issue  this would be a mistake made by a human and U cant really trouble shoot this   make sure everything is plugged back up and nothing is  under the intake and so on.
