ok if you have a code for glow plug# ***** is possible the injector or the glow plug on that cylinder has a problem have you check the resistance on that glow plug or switch that glow plug to another cylinder see if the code changes with the location

or check the Glow Plug Control Module (GPCM) scan data list for the resistance of the #6 glow plug.
A good value will be 0.4 - 0.9 ohms. If greater than spec, check the resistance of the glow plug.
If the resistance is out of spec, replace the glow plug.
