I have an 05 6.0l ran fine all day. Stopped shut the truck off went into the store and came back out and truck would not start. Tore the truck apart found that the o ring on the oil cooler cap was all chewed up and chunks went through the oil hole through the screen and went I guess through the hpop to the ipr valve the screen on the ipr valve was collapsed and had a piece of it logged into the ipr. I replace the ipr valve replaced the o ring around the cooler cap and cleaned out all the chunks of o ring. After putting it all back together it still would not start. Is it possible the hpop got the chunks in it and might be clogged? Any insight would be great thanks!
No I do not I did do a test I found in another thread on this site with the icp sensor that said to put a multi meter to two of the three wires going into the icp sensor to see what voltage is coming out. They said if its .80 or higher then it's 500 psi or higher oil pressure. Mine was read over 80 not sure if that's accurate or not
We would crank it about 10 seconds at a time. We crank it when ever we are checking other things like making sure it's getting fuel and all. What exactly are the injector spool valves, what kind of damage could it cause there?
