2010 no start

Help!!!!

I had a 2010 Tundra with the 4.6 V8 brought to me. I am the heavy equipment mechanic at the docks. Not my thing, but it was just a blown head gasket. Got it all torn down and the gaskets changed. Re-assembled the top of the engine and had crank, no start. Thought it was a timing chain issue. Tore it all back down to verify timing. Timing is perfect! Still wont start! Checked fuel, its good. I have no spark at the coil packs. I replaced the Crank sensor and still no spark.
Chiltons has hardly any info in their shop manual.

I really need a pin diagram for the main ECM connector so I can test continuity through the harness. Any other suggestions would be greatly appreciated. I work on million dollar equipment, yall can only imagine how much crap Im getting over a 400k, 15 year old truck!

Thanks!
