was the truck sitting for a few days before you removed the motor? the fuel could have flowed back into the tank if it sat long enough causing the pressre in the rails to be low. theres a check valve on the fuel pump that keeps the rails under pressure and prevents fuel from flowing back into the tank. that may be your problem. if you can, at some point, check the fuel pressure when its running. on a 5.9 it should be 48-50psi.

I wouldn’t worry about it unless you have some sort of performance issue.
