08 Pt Cruiser won't start
 

Hey everyone, I've got a 2008 Pt Cruiser with 158,XXX miles. Last week it over heated when the bottom of the rad cracked. I got it towed home and replaced the rad only to find out that it wont start. I've replaced the ignition coil and the camshaft sensor. I have spark now and all injectors work,alt and battery were replaced 8 months ago. Timing is where it should be as well. I can't for the life of me figure out what is wrong, an ideas or suggestions?

Do you know how to inspect for a blown head gasket???
And have you rechecked your previous work that you may have unhooked or damaged any wiring when replacing the radiator?
