Don't worry about it. If you have a bad glow plug it will set a code and will tell you which cylinder is bad. If you do have one bad then I would change them all since you have the wheel liners out and the plugs are cheap enough, about $10 each. "0" resistance means it is an open circuit, so one of the probes is not making a good connection, probably your ground to the block.

I went from all is fine starting to having to plug in the block heater to get it start on a warm day. I since put it on a code reader and it says 1-8 low voltage code or something along those lines. I would think with all of those codes, it might be something else? Anyway to find out prior to pulling the wheels etc?
... Have you a clamp on ammeter to go with your fluke mm? If so, reading current will tell you. ...
Many clamp-on ammeters measure AC current only, and will indicate zero no matter how much DC current is present. Make sure you know what your instrument is capable of.

- Hella headlights (highly recommended)
- DOT C-2 back end (also recommended)
- R-12 air conditioner converted to R-406a. Saved ozone and money
- 4.1:1 final drive converted to 3.4:1. Quieter, better mileage but it's a good thing I live in the flat Midwest.

- Never did get around to converting it to french-fry oil, which is why I originally stumbled upon this site.
I did have the initial #8 cylinder code pop up and two weeks later, all of them. I am guessing it's the GPCM. Be difficult to believe it would be the harness's and all the plugs at once. The truck runs great when it warms up, it's a bear to start cold and it run's like crap!
