So need HELP!! 1986 6.9 .. replaced glow plugs, injectors, return lines, electric fuel pump, fuel lines, if I give it a huff of starting fluid it will pop off then die off. Give it one more huff it will start right up and stay running but produces lots of white smoke as long as it runs!.. leave it sit for a day no leaks anymore won’t start even when push button starting the glow plugs . I can’t figure it out po has a used reman ip in the bed wondering if that’s the issue , would this course it not to start without fluid and when running produce white smoke ?.. and it’s not head gaskets it’s not sweet it’s like raw fuel almost please HELP!
