Ok so the day has finally come. I have figured out what was causing the lack of power in my 2013 EPA10 Paccar. It was the fuel pressure control...

What do you mean by bad pump but no codes. How do you know it's bad?
Most of my Davie work has been on my EPA 10 which is much different than an EPA 17. My 2020 doesn't have the MX13 but the MX11 which is different...
As far as techs go, you are pretty much correct. I have access to Davie and I've taught myself a lot of stuff and know more than some techs do....
LOL I will definitely give an update or a fix when found. So many people on the Facebook pages for Paccar don't ever come back with a solution....

Ok. So the mechanic has the truck and is going to put in a different ECM to see if that is the problem. If not then I'm going to have him clean...
What's your opinion on the EGR flush? Worth it or better to pull each sensor and the venturi etc. out seperately?
