Where do y'all recommend taking a '00 powerstroke to have the glow plugs replaced near the Concord? I don't mind paying for good work, but I want the most bang for my buck so to speak. Live in Concord, work in Huntersville & travel to Albemarle on a regular basis, so anywhere in or near that triangle would be preferred.

The last couple of times I driven my F250 its been hard to start, so I tested everything this morning. The GPR, batteries & fuel pump tested good and 7 of the glow plugs are reading 0.3/0.4 ohms and the last one is reading 1.4 ohms. My powerstroke manual says 0.1-2 ohms is an acceptable range but the interwebz say 0.8-1.2 ohms and I'm leaning more towards them. So I'm probably going to replace all 8 since I think they're all bad or getting close, but first I'm going to test them again with a different DMM since I'm skeptical of the same reading of 7 of 8 glow plugs.

Any reason you aren't doing it yourself? It's not that difficult, took me about 5 hours on my old 7.3

Haven't ruled out the DIY route, just preparing for the worst. When my OBS needed them, I didn't have the right tools & was working on it outside in the rain. Long story short, there was a lot of words said & I finally gave up and took it to a dealership...wasn't happy with the work, so they aren't in the running this go 'round.
 
No special tools involved.
Just make sure to get OEM parts, and go ahead and replace the valve cover gasket while you're there since it has that built in plug.
 
I think I would do a volt drop test from the positive battery terminal to the glow plug feed, verify you've got a good solenoid and wiring, this isn't a difficult test and can be done with a standard dvom. From there I use a test light on the harness to b+ to test wach individual glow plug. As mentioned above, very easy job!

Yeah, I've seen the write-ups & videos. Was going to order the Motorcraft ZD-11 plugs, but was on the fence about ordering the gasket & wiring harness until I get under the valve covers since the gaskets are supposed to be reusable.

Kinda confused here...already tested everything. Only reason I'm retesting with a different DMM is I'm skeptical of 7 readings that were exactly the same, its more of a test of my DMM than to verify bad glow plugs.

I didn't read where you did a loaded voltage reading on the solenoid & wiring, if the plugs are bad, and that's it great. But if plugs don't have adequate current, it won't help much to change them lol. As I mentioned above, the test light (must be a incandescent type) method is typically a bit faster testing wise, and every bit as effective. Pulling resistance on each plug is just a bit more time consuming and doesn't give you much more data than a test light.

It is just a little out of your loop but Crawfords garage of stokes ferry rd is Salisbury does outstanding work and only uses factory oem parts on everything right on down to oil filters and all or sprinkles complete truck repair also in Salisbury does great work I would lean toward the valve cover plugs on the gasket and the wiring harness plugs imho
 
Its worth a $25 try to replace the gpr. On my 7.3 truck it was kicking on running the glowplugs for about 3secs before it dropped out.
