IPR questions
I have an 03 with a hot start issue. I bought a scan gauge and can see it is not meeting the 500psi needed when hot. It has a new IPC but did not fix.The IPR is going to 75 to 85% during crank. Could the IPR be sticking or do I have a IHOP leak? What test can I do? The problem went away for 2 days then came back.

Pull IPR and Check the Screen for Damage pushed up in or Holes

As Blade said above, the 75-85% you are seeing is the command TO the IPR, there's no way to verify it's doing what it's being told to do. You mentioned seeing <500psi on ICP when hot. How does it act cold? (ICP/IPR)

IPR questions
I am using motorcraft oil filter with factory short cover.
I did check ICP voltage but did not write it down. I will get them when I leave work this afternoon and post values. I am going to pull IPR saturday, if the screen looks funky is that a gauranteed failure?
It has been this way about a month, got there gradually. I bought the scan gauge last week and the next day it started fine hot but only for 2 days.

IPR/IPC values
I didn't write down the IPV but the IPC runs from 220 to 380 on a no start.
The IPR goes up normal to 70 to 80% during start or no start.
I have replace the IPC sensor, no change in the issue.

still at itq
Drove home from work, shut off and verified it still is a no start hot. IPC pressure 200 to 300 during crank, IPR 79%, noticed battery voltage going down to 11.5 during crank. Is that normal?
Ficm power did not drop below 47 during crank.

After reading ALL the thread your ICP values are bouncing around for some strange reason. Pull the IPR valve and check it. If the screen is compromised then that's the first thing I'd change.
