It's probably not a coilpack. They are pretty durable despite some isolated boot breakage issues and the car will run (extremely poorly) on 4 coils. You can test them by checking their continuity/resistance with a multimeter, or, barring a multi, spark it off onto a bit of metal (i personally do not do this).
Checking for physical spark will verify the state of your ignitor.
Pull all your sensors (crank ps, cam ps, etc). They could be dirty with some slightly magnetic dust/dirt/crud.
Swap in a known-good battery.
Maybe Harvey or someone with more diagnostic experience can chime in.
