1.6 Wave. Cranks, no start, no codes

My GF's new to her car ran great yesterday. Parked it in the garage. Today it cranks, doesn't even try to fire.

Pulled plugs, found oil in the wells, attribute that to valve cover gasket leak (unrelated to no start).

Check 2 plugs, no spark.

Also no smell of fuel.

Check all fuses and relays, they are fine.

I can hear the pump pre-start.

Pull DTC's...all clear?!

Check related connections, battery terminals etc, no obvious problems.

I'm leaning towards crank or cam sensor. I have the crank sensor pulled now, figured I would start with it, since it's easiest. Parts store tomorrow.

What do you guys think?

Also, why no DTC's?

Thanks!
