[caper01]

hi i have a 01 f550 with 7.3 and 5 speed tranny. i just had it to the dealer and had the hpop changed. one of my steering lines started leaking today so i shut the truck off to check now it won't start. will crank over fine has fuel, all fuses are good, the resiviour for the hpop is full. wondering if the is any way to test the hpop for output or nething i can try. also its a remanufactuered pump. thanks

On an 01 model you can test the HPOP by blocking off one high pressure oil line and hooking a 4000 psi gauge to the other line. IT's harder on a 99-up truck because the high pressure oil lines are quick connect so you have to get the ROtunda adapters or take the fitting out of the oil rail and get some fittings to plug it off. Crank it over for 5 secs and it should hit 3500 psi if your pump and IPR valve are working correctly. Injector O-rings will cause a no-start as well but without an ICP reading from a scanner you can't be sure it's a high pressure oil issue.
