You probably won't see your IPR duty cycle reach 85% unless you have a long crank. You can check this next time it doesn't start for you. Also unplug your ICP next time it doesn't fire up. If it starts after you uplug the ICP, than your ICP is no good.

WebDuring the suction cycle or one-half of a revolution, the pistons create a vacuum that forces oil in. On the other half of the revolution, the pistons discharge oil. In the 7.3L HPOP, the pistons measure 0.436-inches in outer diameter. A 15-degree pump’s internal cc size is roughly 6.8 cc’s, while the 17-degree pumps is 7.2 cc’s. WebHelloCustomer The IPR duty cycle should range from right around 24% at idle to 85% WOT. ICP pressures should range from about 650psi to around 5000psi at WOT. These …
WebIPR Duty Cycle – 18-21% At WOT in neutral your 7.3 ICP should be – 1100-1200psi – With a caveat that after s/n 896812, after 3 minutes of WOT with no load, the number would be 1800psi. Because at WOT, your 7.3 ICP pressure number will spike and then level off if you stay on the throttle.
