Cummins fuel prob

check the fuel shut off solenoid but the mechanical not electrical part make sure everything is moving freely sometimes they like to get stuck inside and drops fuel Psi

 

I had lack of power on n14 it was because boost sensor in the intake manifold was bad.
Mine gave a cel not sel

 

Xetra did you truck blow smole because of that bad sensor?

I have a code mid 128 pid 105 fmi 4 From reading on websites it is intake manifold pressure voltage below normal.

When idling it has blue white smoke, not noticing power loss, just bought the truck and necer hooked to trailer.

 

Yes it would smoke like a fogging machine.
