SES light on ....P0673 ....what is next ?
 

This thing is really pissing me off......2 weeks ago the HPOP orings and now this
Can anyone tell me the most likely problem ? is it the glow plug ? harness ?
I cleared the code Thursday and it never came back until today :argh:

P0673 Glow plug #3 circuit failure

I would check the wire harness... Make sure the GP is completely connected... Go from there.

Thanks......Never had it apart before........what all do I have to do to get to it ?
Also..........stupid question......1,3,5,7 are left hand (driver) side correct ? It doesn't have the crazy Ford gas engine clinder #'s does it ?

Odd on the passanger side, even on the drivers side...

Check the wire harness first, then pull the valve cover... not hard.

What exactly am I checking for on the harness ? Could this have anything to do with the massive amount of oil I sprayed in the valley when the HPOP oring went ?
