I have a 2011 Hino 268 that will regen by pressing the manual button on the dash but no heat. It will regen for hours but the muffler isn't getting any hotter than normal. I have a dtc, P141F (burner malfunction). Tried a few things but don't really know what to look for. We removed the burner injector and it was pretty gunked up along with the igniters. Cleaned them and reinstalled and did a regen but all the same, loosened the lined that connects to the injector and its not getting any diesel during regen for some reason. Any thoughts, I'm new to Hino's and don't really know where to go from here. Any help is greatly appreciated.
