IPR electrical values

I've been having problems with my high pressure oil system . 2 weeks ago my truck died while going down the road . ICP would only build to 175 to 200 psi. So new IPR. One time it started and all was good until the duty cycle shot up and ICP pressured dropped . I have a new IPR to put in but was wondering what the electrical value is at the IPR plug. I'm getting 10.3v to 10.5v , is this normal or does the value raise and lower according to the ICP and duty cycle . Or does the IPR regulate the pressure by being either opened or closed? Thanks

put in new IPR and still no change. I don't want to put in a new HPOP yet , this one only has 1500 miles on it. Is the PCM , possibly the problem?

I have checked all the wiring in the engine compartment. Noting is chaffed or bare . When the truck shut down 2 weeks ago, it just quit, no chug or stutter . It just quit like it had an electrical issue. One time after that, it started and ran like there was no problem until it reached operating temp after 4 miles. Then the injection pressure started to drop and the duty cycle went up to 64%. I put a new IPR in yesterday and it still only makes 175 psi when cranking. What I need to know ,is the voltage at the IPR plug . I'm getting 10.3v to 10.5 v when cranking. I'm thinking it needs 12v to fully close the IPR. So , can anybody check their 7.3L and let me know what the voltage at the IPR plug with the key on and when cranking ( you'll need 2 people for this). I have a feeling that the computer is the problem but don't want to replace it unless I know its the problem.

Are you sure you got good parts?

You say that you replaced the ipr and Icp and it is still doing the same thing?

Last time I had the issue of the truck dieing when it reached operating temp it was the ICP sensor.

I replaced it with a new one and no issues since.

I do not know the exact spec's for the ipr voltage but you should not need a full 12 volts for it to open or close the valve.

Here is what I would check first

What is your low pressure oil pressure at you can check that on top of the HPOP resivor?

It is possible you have an issue with the low pressure oil supply causing it not to have enough oil supply for the high pressure oil pump.

Found out today that the 10.5v is normal. I measured the voltage on a friends truck, so that would eliminate the computer. I'm going to pull the HPOP and call the company. It should be under warranty , it only has 1500 miles and 4 1/2 months.

Forgot to mention. I checked the LPO and get 26 psi when cranking.

how did u get 26psi at cranking?

we are having an issue right now as well. Sounds exactly like yours.

We tested a running truck and you dont see any LPO pressure cranking. (6-8psi). As soon as it starts, it jumps up to 27-28psi.
