Message: [QUOTE="70jeeper, post: 147610, member: 1669"] The first pump had a delayed start and a weird romp off throttle along with all the current problems, the second pump fixed the start and romp problems but had the same current issues.All of these issues started with the pump install. With the SRP1, the cold idle pressure is 520-530 psi at 13%, hot 420 -430 psi at 12% and the highest I have seen is 2,550 at 37%, the stock 15* idled at 470-480 psi hot and would top out about 2,700 but would drop to around 1,650 under load. Did try unplugging the ICP and it ran a little worse. I also read on All Data today that the injector requires a minimum of 500 psi to operate, is that true? Woodduck, along with injectors, orings have crossed my mind. What led you to check/replace the orings? Did your duty cycle change before and after the oring change? [/QUOTE]
