I was able to sort through my problems. Very fortunate today (somewhat). I was able to carefully drill into the valve cover bolt and remove it without damaging anything, get a replacement bolt, and finish the standpipe/dummy plug effort today. Of course, starting the truck took several cranks, but it lit and I took it out for about 30 minutes. Throttle response did seem a little delayed at times.
After coming back in, I shut it off for 30-45 seconds and tried to start it again. Same no start condition... after letting sit for 15-20 minutes I tried to restart to get my ICP numbers: ICP_V is at .6; ICP_PSI is at about 305. I know that if I let it cool down enough, it will build the minimum 500 PSI to start up; but with the ICP sensor plugged in, it just cranks and cranks.
After unplugging the ICP sensor, truck still struggles to start up, but it does (I'm thinking there might be some air still trapped in the system?). ICP_V is at 0 (of course); ICP_PSI at about 652.
Would this indicate a bad sensor? I can't really tell if there is oil on the plug or around the base of the sensor, and I can't see any wire chaffing, but this is what I'm leaning towards as I have about checked everything else off the list.
As I said before, last May I updated the STC fitting, replaced the IPR screen, and have now updated the standpipes/dummy plugs. (Slowly but surely I'm building a rock-solid rig). Any help or advice would be appreciated
