by updating you mean watching the icp drop to 0? when I turn the key on I can see the icp changing on the screen. Also you have it right I will go out again and leave the key on for a few minutes and see what I get. But when I start to crank it it goes to 0 fast.

I wonder if your taking the readings to fast becuz on both pics the IPR% was at 14.4
14.4 IPR% is great when the key is in the on position
But 14.4% while cranking is not right the IPR number should skyrocket untill it starts it should be at like 70-80% IPR during crank
I think that your taking the numbers to fast the SGneeds time to update during crank

when you see the numbers on the SG screen change it has updated at this point you will want to note your readings
I usually set it to volts and when that one changes you know the SG updated

Somethings definatly off IPR% never changed and it should have
when you went to crank it IPR should have skyrocketed BUT IT DIDNT IT NEVER CHANGED
to me it looks like a IPR/ICP wiring problem
At 14.4% IPR its just draining all the oil back to the oil pan and not making any HPO
I think your getting close atleast headed in the right direction

once you unplug the harness from the IPR silinoid your not testing the IPR anymore
I beleive the SG readings are correct
ElewctricaL PROBLEMS SUCK
Id be checking that harness over good

I was more thinking about testing the wire to see if the IPR would be getting the voltage needed for it to close when the engine was cranking. Not testing the IPR. I will start tearing down again and looking at the harness again

I beleive that the problem is in the HPO system
according to the readings its not making any HPO to fire the Injectors
