fuel supply should be. Greater than 590 mL (20 oz) in 10 seconds clean and good quality. The high pressure pump output volume is greater than 70 mL (cranking the engine for three 10 second cycles). There should be no fuel flowing from the Pressure Limiting Valve while cranking the engine. While cranking the engine for two 15 second cycles (30 seconds total), return fuel flow from the high pressure pump is less than 500 mL. While cranking the engine for two 15 second cycles (30 seconds total), return fuel flow from the injectors should less than 20 mL.

I did flow test it was 50 ml per minute and I got AG up and running fuel pressure senor shows 7063. And set point was 6886. At idle cold

If the code doesn't trip at idle,testing at idle may not lead you to the correct conclusion.It will only be the starting point

I don't have any codes right now white smoke no power just replaced fca and injectors was getting high rail pressure code

White smoke after injectors?suspect bad injectors,tubes or installation issues
