    You Tube Hoglund Buss IPR, DT problems and similar stuff. They have some pretty good information. It will take you some time to get through it. Maybe then you can fix it? If not you will have a lot better understanding of what questions to ask here. Some people on here know a lot about them.

    12v to ipr and second wire computer controls resistance to control ipr. If plugged in will show voltage but unplugged should show 0v on one terminal. To test ipr you can ground out that wire while running to send pump to full stroke for max oil pressure test.
