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?

I suspected it wasn't related to my problem. It will run for 2 seconds at the most. Most times it just tries to fire and gives up. I've been watching the hpop oil level and it seems to be dropping rather fast as I crank it over. This is so frustrating as I went through this last week and it turned out to be the batteries. Two days later I'm broke down again.

did you try it with the icp unplugged? you may have a leaking hpo system.

Well, it looks like its the oil pump pickup. I have no oil pressure when cranking. Inspected the oil pump and it looked fine but dry. I'll pull the pan tomorrow.

That's one job I hope I never have to do again!
