j hancock Posted April 15, 2020 Share Posted April 15, 2020 One or more of the injectors may need to be rebuilt because it is dumping fuel. Do you have maint history with the truck? Engine hours? Been rebuilt? Has cylinder compression been checked? More details the better. Quote JimIt doesn't cost anything to pay attention.

Could be the econovance has failed the little ( box in front of the fuel pump) you can tri put 12V to it see if the issue clears it up! the solenoid could be weak on this !causing this issue!
