What prompts you to pull this plug..........presumably, nothing on the meter gave any indication..........??

That would confirm to me that this plug is not creating sufficient temperature for ignition and I would change it. The tip temperature must be quite low.

We usually get temps below zero a few times a year here though one year it got down to 30 below and I have seen it go ten days below zero with highs of near zero and lows of 20 below (F).
Of course the car will refuse to start on a day like this when it has been fine before. To me, anytime I get irregular idle after a cold start I start looking to the glows. I'd rather work on them when it is 40 degrees or warmer than below zero. I can get the car in the garage with some effort but the race car is in the bay next to my tools so I usually work outside that bay. Changing them one at a time works fine when it is your regular driver and you can get it inside whenever you wish to change one or two. When I am looking at the diesel my lovely daughter #4 has over in muncie I look at it completely differently. A non start over there is a major issue for me to deal with....

Same with my glow plugs, I had one fail, replaced it, another blew a week later, replaced that one, and its been fine since, so the other 3 have lasted nearly a year since then with no issues. I keep a couple on the shelf in case any fail.

Did you try to double-bump the GPs in the beginning to make sure there was enough heat?

GP testing ;
Measure the resistance of each GP. If any are high or show open circuit then they are bad. Replace them. As there is no guarantee that correct resistance = good GP, remove the others & visually test. Ream the GP holes. Replace the lot if they have been in for a number of years & 1 or more are bad. Keep any good ones in the car just in case any of the new ones fails prematurely. Interesting that I cant find any reference from the GP manufacturers recommending using resistance testing to determine if GP's are good or bad. Maybe those promoting can provide such. Much of the GP resistance stuff appears to originate from a Diesel Giant tutorial. Or if you wish to save time, just remove & test visually.

Do you or any of your old mates have any information from the GP manufacturers to substantiate your resistance test? Probably not or you would be posting it. Most of the resistance test supporters go quiet when they are reminded that the test only shows when a GP is definitely bad. It does not show that it is definitely good. The only way to show a GP is definitely good is to remove it & test it. On that point any intelligent person would concede.

I fought a very similar sounding problem where I would only get one or 2 chance to start the engine (in the winter time) before the starter would bog down and grind to a halt. I finally pulled the starter and rebuilt it with new bushings and a new used good rotor. The old rotor was hitting the field coil iron core and pinched a winding creating a partial short. The short and rubbing between rotor and field coil caused the bog down. I wrote about it in a post with pics a while back. It's nice to have a good starter now with long cranking times without slowing down. Don't need it though, my car starts within a few milli seconds upon cranking. One way to check if your starter has a short is measure the current. My bad starter was drawing around 400 to 500 amps as I recall, due to the short, the energy went to heat up the wires instead io spinning the motor. At the time I didn't know what was normal cranking current on a starter. With a good starter, I think the current should be around 300 amps.

I thought our starters had bearings instead of bushings.
