Bad IPR
Can a bad IPR cause a hot no start issue. I've replaced stand pipes and dummy plugs, STC fitting about 60000 miles ago.
When i got truck going today after towing it home and cooling down, IPR was reading 80% at idle. Pulled IPR ohmed out at 5.6
What are the symptoms of a bad HPOP
When you do get truck running ICP is surging up and down, sounds lopy

It could, as the number given (for example your 80%) is what is commanded, but the actual movement of the solenoid isn't known.
So the PCM wants more pressure and commands more %, thinking it should see more pressure, but if the IPR is bad and not opening correctly then yes...
Could be crud on the screen or a collapsed screen. Or it flat out fails when hot.

Sounds about right for Ohms per a Good Sensor IIRC my notes state 8 ohms or less
Like Josh says IPR has No position sensor so God Only Knows
Do you Run OE Oil Filter and OEM Oil Filter Cap this is Important
It would Also Realy Help if you could post ICP in Addition to IPR% when there is a HPO Concern

Also Might not hurt to Post
ICPV at KOEO too
Thats Just me though I try to gather as Much Info as Possible before making a Desision
Then I would Pull IPR Out to Inspect the screen
then go from there
Id say the Majoirity of the time with a Surging Idel the IPR is at Fault and Usually a Plugged screen

The icp v is .80 which i think is spec.
Truck has only seen factory filters and cap.
When I pulled ipr, screen stayed in pump so had to dig it out, but it looked fine.
Thanks for all your replys everyone
