LB7 crank no start

LB7 crank no start
its an 04 lb7 duramax. to start, heres a list of what all has been replaced...
-fuel filter housing
-cp3
-suction side fuel lines
-injectors
-injector supply tubes
-FRP sensor
currently getting 2 mpa at crank (fluctuated between 1 and 2). can hand prime at housing up to 10 psi (using test port beside alternator). have pumped until hard and bled at that test fitting as well until no air came out. when pumped up to 10 psi, slowly bleeds down to zero over the course of about 2 minutes. when cranking, ticks down to zero in about 15 seconds. no codes when scanned either
any ideas on where to look for an issue here?
