I completely rebuilt my Ford 5000. Had the pump gone through and rebuilt the injectors. Smokes something horrible. The white smoke will fog the entire shop within minutes of starting. Tried advancing the timing 19 then 25 then 33. Still white smoke. Pulled the exhaust manifold to see which hole wasn't firing. It skips around. Usually the #1 and one or two others do not fire could be 2 3 or 4 sometimes 1 fires and not 2 and 3 or 2 and 4. We thought it might be the pump and took it back to test they said it was fine. We took the injectors back to have them tested, checked to be sure we had the right replacement cam gear. Pulled the head and pulled a piston to be sure we had the right piston. Which according to the book we do. I am completely stumped. What would cause different holes to not fire and then fire?
