Hello and thank you for using Just Answer. My name is ***** ***** I will be assisting you with your question. I am sorry that you are having issues with your Mack. On your issue one thing that I would check is the fuel pump gear. We have had issues with these slipping and when max fuel is needed they will slip and sometimes will stop all together causing the engine to die. I would also check the wiring for the cam sensor and make sure the connections are good and no obvious wiring issues. If those are fine I would check the unit for faults and view the sensor data while in operation. Please let me know if you have any follow up questions on this. Thank you

Replace the fuel transfer pump when I drive it an get into 5th gear starts losing power and kicking white smoke injectors maybe
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 2 years ago

It is a possibility. The other thing i would suggest is connecting a fuel pressure gauge and make sure the pressure is not tanking when this happens.
