BOOST!
So i'm working out the bugs on my high mileage Excursion with the 7.3 powerstroke.
I'll try to keep it to the point. The glow plugs are not firing when the key is turned on.
Bottom line is the ground signal from the PCM isnt getting to the GPR. Forscan shows me the EOT is at about 62°F, and the PCM is calling for the glow plugs to light.
So I'm thinking I either have a broken connection from pin 101 of the PCM to the GPR, or the PCM itself is bad.
Next steps are to ohm out the wire from the GPR to the PCM. If I find that to be ok, then I monitor pin 101 right at the PCM while the key is cycled and see if the PCM is bad.
Thought I would throw this out there to those more in the know to see if I'm on the right track.
