Engine cranks but does not start?

Timing chain (TC) blew out and had to perform a full Cloyes kit replacement.

Timing chain issues with GMC Canyons are a well-known engineering defect.

The funny thing is, it takes about 30 mins. To replace the entire TC kit, but it takes hours upon hours just to tear down the engine to get to the TC.

Now, we have a 'crank no start' situation.

Here are a few test/repairs/inspections we did:

* Timing chain alignment was verified (pretty straight forward)
* Oil pump kit replacement, as the TC destroyed the pump.
* Extensive resealing and gasket replacement
* New spark plugs (as a service step)
* Ignition coils working properly/no DTCs
* Have spark upon cranking
* Have fuel upon cranking
* Fuel injectors working properly/no DTCs
* All DTCs cleared and re-scanned for any new codes; 100% pass/no faults
* All fuses/relays checked OK
* Solid battery power
* Cleaned throttle body (as a service step)
* ZERO compression reading on the gauge (now that took us for a loop)

My business partner seems to think there was a mistake made in the TC installation, but we cannot figure out what that would be.

My gut instinct is, for some reason or another, the Pass lock has kicked-in, not allowing a start.

This is a tough one.

I welcome all your questions, comments and concerns.
