no start with a strange fault code

Hi all. My truck won't start for more than 2 seconds. I checked the codes and got #236. Under probable causes it says restricted inlet/exhaust/supply hose. Missing hose. Anybody have any idea what that is? Thanks in advance.

I don't think that code is related to the no start. It relates to the map sensor, its saying the pcm is using inferred data instead of actual signal from the map sensor.

it will continually start for only 2 seconds?
did you try it with the icp unplugged? you may have a leaking hpo system.
