CM870 power loss

[Redland1]

Since I can’t figure out how to get my Inline 6 to work I took the truck to a junkyard mechanic and he put his computer on it which showed the intake manifold pressure sensor as not connected but I just changed it out so we couldn’t figure that part out.But as far as the issue he found the turbo control box to be bad and he happened to have one on a truck he has as parts.Once hooked up the turbo could be heard.As far as the sensor and inline 6 I still have to figure those out.
