Message: [QUOTE="Lt.Dan, post: 1537890, member: 24137"] I think you have IPR and ICP mixed up, because your IPR is measured in a percentage (how far the valve is open) and ICP is measured in PSI (pressure of oil). And you are saying you are making 3800psi of ICP??? That's borderline dead heading the pump, or you have some gnarly twin pump with an extended reservoir. People rarely see over 3000psi, and are usually around 2800psi. I would be looking into your HPOP/IPR, because something isn't right there. Sounds like there is a restriction between the pump and injectors, making the pump spike pressure, but then the injectors cant fire because the pressure isn't making it to them. As stated above, we need to know your IPR duty cycle %. [/QUOTE]
