Why will my 2006 Chevy cobalt not run?

What is your question?

After driving my 06 Chevy cobalt 2.2 sohc for about 2 hrs I returned home,where it sat n idled until I unloaded it n drove over a sharp hump into garage.it has not ran since. it is getting great fuel pressure i checked all fuses n changed some relays.It sounds normal when turning over(not jumped time) If it was the Coil pack,wouldn't it gave started missing some when its was hot fiirst? I have a coil pack that is a Dohc 2.2.- Will it interchange with this car's Sohc 2.2 ?They look the same.The coil pack is just a gamble for me.Do you have any suggestions? Thank You, my name is Hoopr
