not mine but belongs to neighbor. He has changed fuel filter, bled at injectors, fresh fuel, air filters clean. Will idle but won't accelerate. lot's of white smoke. Wondering if it could be turbo problem? :confused3:Any ideas would be appreciated.

Check fuel flow from the tank then check the banjo fitting at the fuel lift pump inlet side for trash in the tube, fitting and bolt. Check the screen in the top of the lift pump. If that all checks out, check the lift pump for proper fuel delivery. If that all checks out the injection pump becomes suspect.
