fixed my starter issue, another mistake by me, i had put the lever of the solenoid on the wrong side of the spring! learned quite a bit about the difference between this starter and the old style though in the process...
so now the truck is not building rail pressure when cranking. I unplugged the RPS to max it out and still not building enough actual pressure. its basically 0. I tested return lines to see if i had stuck injectors or a bad cp3....nothing...so i test cp3 return, nothing....i tested with and without the RPS plugged in. nothing...so I make sure my MITUSA is actually pumping fuel while cranking...nope. however, when i pressurize the system with an air gun at the filler neck, fuel blows right past the pump. so it shouldn't be restricting flow to the gear pump of the cp3 that much that it wouldnt start, no? My only two thoughts are either the RPS is bad, even though unplugging it didnt help...or I have a crap, brand new cp3 from II. unless I could have an injector stuck open? not sure here. need some advice.
