Hello, did any of those codes come back? I see a lot of communication codes.
And is this a Hybrid? Seeing that there are some voltage codes, low voltage can cause communication errors especially on networks that are 12volt pull down type circuits. Canbus is only up to 5volt with a 2.5volt bias on the circuit, but some other networks can be 12volt type.
If this is not a Hybrid, we can pull up the ECM diagrams and check powers and grounds. If you turn the key to the on position, engine off the Check engine light should come on, if it doesn't the ECM is not being powered up,
Here is the crank position sensor, it's a 2-wire sensor, a variable reluctance sensor that produces a sinewave signal to the ECM,
Here is its location, the green is the trigger wheel for the sensor, verify the wiring is good to it.
But I would verify power and ground to everything else first, there is quite the process for replacing the crank position sensor and then a crank relearn procedure as well.
