Have you checked the glowplugs and the relay?

Customer: replied 1 year ago.
i have they are working i notice the engine is running rough what would a crank sensor problem do?
Expert:  Ray M. replied 1 year ago.

a defective camshaft sensor will cause a no start or stalling condition. When it is running cold is it running rough like it may be misfiring?

Customer: replied 1 year ago.
it is ! but when it warms up it still runs rough like its miss firing ? now how about a waste gate soloniod or watse gate not opening due to low vaccum or turbo problems ?
Expert:  Ray M. replied 1 year ago.

What you likely have is a problem with the under valve cover harness, the connectors would come apart and cause injectors to fail to fire, this also disconnected the glowplug connection and caused a hard start cold. to repair you need to remove the valve covers and install the special clip available from ford. the part number is *****
