Mook can split all this.
Within 1-3 key on cycles 30 seconds each, powerstrokes with electric pumps so super duties all had good clean fuel ready to fire. With mechanical trucks only thing you can do is crank, maybe fill the bowl to help. Or hook up an external lift pump but really there is no damage going on.
The issues were definitely the reman ih hueis. Garbage according to my fuel guys.
But for oil side, just crank, there's nothing actuating in there until they hit 500 psi, so no dry firing of any kind.
This is how I diagnose if for some reason I don't have a scan tool. If you crank a 7.3 and can hear injectors clacking thag means icp system is fine, move into a fuel side diagnosis. If you here no clacking or actuating then you got a oil side issue either mechanical or demand
