Excursion Stalled NO START 0psi ICP
My Excursion stalled on the highway and will not start. Towed home and fully cooled down and still NO START.
I had already replaced the STC fitting 6 months ago but now this problem. The truck has 90,000 miles and is very well maintained.
BASE oil psi is OK. Cranked and oil filter housing filled in 5 to 6 secs of cranking.
The IPR valve screen is clean as a whistle. Looks new, no damage and no filings or any contaminants whatsoever.
I am going to pull the HPOP and replace with new unit I ordered no matter what I find.
I am also replacing the IPR valve since I ordered a new one anyway.
BEFORE I pull the HPOP I want to do an air leak check.
Can I do this since the turbo has been removed?
I want to remove the valve covers as well since I will be replacing the standpipes and dummy plugs.
Basically with the valve covers removed and the HPOP cover removed but HPOP still bolted in can an AIR LEAK test be performed at this stage?
would I hear if air was leaking at injectors or standpipes at this stage?
I just want to fix this but also update all the components that will probably fail in the future anyway.
