crank no start
having a crank no start cold or hot
i am getting base oil pressure checked from oil filter bowl
when cranking ipr 84 icp goes up to about 100 at the max dont really want to crank to long just changed the starter.
b4 i replaced the ipr i was getting a max of like 10
after ipr replacement i only get up to about 100.
i put air into didnt hear any leaks.
ive opened up the hpop cover to see if the stc fitting **** it looks good i put air didnt hear any leaks.
what are the odds of my hpop going out??
this was all of the sudden no warning drove the truck all morning started just fine hot
went to turn it off at a jobsite and when i went to try to turn it on it just cranked.
im gonna end up changing the hpop either way im that far in why not just change it but just wanted ask yall to see what else i could check.

i just feel like if it was a hp leak it would start cold and the icp would be higher in the 300s

Hey, I had a similar crank no start issue on an 05 I had. I had to replace the sensor on the right valve cover and the one down below behind the turbo. Now, I'm trying to remember the names of which is which to identify them, but I'm drawing a blank. I wanna say Injector Position Sensor and Oil Pressure Sensor, but that was a few years ago so I apologize if I got it wrong.
I do recall the one on the valve cover was leaking oil on top and that shorted the circuit. The one under the turbo, the new sensor, also had a bad connection, so I would just reach in there with a stick, wiggle the wire and it would start. I'd check for bad connections on the sensors as well.
Good luck.
