Once the key is turned how quickly should it start?

Like the title says; How soon after I turn the key should my 6.0 fire to life? It seems to have to turn over for a few seconds before doing so. I don't recall my old 6.5 diesel suburban needing as much cranking time.

my 06 always takes about a sec or two as well. Just normal I think.

Sometimes mine starts the first second it's turned over and other times it takes a couple of seconds turning over. Not sure why that is. I maintain level ground whenever I park, the temperature is usually the same and I use only one fuel station.

Mine has always taken at least 2 seconds if not 3 of cranking before it fires. It's almost like the computer needs several revolutions to calibrate itself and send fuel.

The engine needs to build oil pressure, hence the delay.
