I know the subjects been beaten to death but no one has the issues im having it’s always fuel pump not priming so I got a 600f4i she runs off of starting fluid so I know it’s got spark nd compression the fuel pump is priming nd I’ve opened her up nd I can see the injectors mist on the initial crank I’ve tried starting her off the starting fluid but she would stall out changed out the old fuel as well any ideas of what I could be missing here ? Running out of ideas any input is appreciated 😊

 

edit* I've tried a new ecm same issue newer fuel rail injectors and regulator and still newer pump fresh gas and nothing last thing is the harness but all connectors have approximately .1 ohms resistance idek anymore don’t wanna sell it but sheesh😂
