So at times when I turn the key to start it is very delayed in turning the engine over. Is there a reason for this I am unaware of or is there an issue? Sometimes the delay is 2-3 seconds long.

Glow plugs

When a pre-set time has elapsed, the glowplug relay switches off the "wait-to-start" light. A pre-heating cycle usually lasts for 2 to 5 seconds. The operator then proceeds to turn the key to the "start" position. The relay switches off the glowplugs after the engine is running (or, in older cars, at the same time the "wait to start" light goes out). In some cars, glow plugs continue to operate for up to 180 seconds after engine start to keep the engine within emissions regulations, as combustion efficiency is greatly reduced when the engine is very cold.

OK so when you get in the truck just stick the key in and turn to start. then let go and let the key go to run. You only need to hold it for a second. The truck will delay the start and start when it is ready. you dont have to do anything else.

Ok thanks guys. I was wondering if it was to warm the glow plugs. Now that I think about it this only happens when engine is "cold". Starts immediately on subsequent start-ups after the initial start-up in the morning unless truck sits all day. Then it will do it again after a long time off. I just didn't know if there was still a glow plug warm up on these new diesels like the older ones I have driven.

These trucks do not have glow plugs. They have a electric heating element in the intake, just like the newer Cummins.
