Sons 300m and I need help please!

Tore it apart last night.
Timing Belt looks new, Water pump looks new. Entire timing belt cavity is clean, no belt dust, and no water seepage.
Worse yet, Timing was dead on.
Pulled the plugs and shoved the scope down the holes. Pistons all look good. They all move up and down like they should.
After work today I will run compression test and use the scope to look at valves.
What do I look at next?
Already checked all plugs for spark.
PCM shows no codes still.
I was sure the timing was off.
