Chances of all 4 loop style being burned out is zero. Buy only enough to replace the burned out one. Unless you have money to throw away.

All I can find locally are Autolite plugs. If it's just one it won't hurt.

I did try fogging the intake with WD40 and it still didn't start but that was before I realized the plugs stopped working.

WD40 is not the same as Ether.

I'm not going to bother with ether. I've never used it and I really don't want to blow a prechamber.

If the glow plugs aren't working, you can use either....nothing there to ignite the either to destroy the prechambers.

Glow pugs aren't really a necessity for tow starting since your're spinning the engine as your towing it will generate enough heat to start. You just might have to tow it a little further.

I'll consider that, I can usually roll start my MINI by letting it roll down the driveway into the grass(about 15-20 feet) but that's a gasser. We shall see what I accomplish.

From what I've heard you'll need more than 15-20 feet. You'll need to tow it behind something for a couple hundred yards I'd imagine.

I've got about 50-60 yards of alley to use

You can't do a pull start or roll start in 50 -60 yards with a low compression engine like yours. I don't think you understand the idea of a pull start. It is to get the engine to spin much faster than what the starter motor can provide thus generating more (sustained) heat in the cylinders. You won't be able do do that in 60 yards. Don't waste your time, again! Do a real pull start or use Ether. Glow plugs will help with a pull start so use them. But DO NOT use glow with Ether.

Very well. I'll reference the manual for pull starting,disconnect the glow plugs via the strip fuse, and see what can be done

Well I inspected glow plugs 2 & 3 and they weren't burnt out. Replaced the new fuse with a second new fuse just because I have them and still no glow plug light.

I can't try ether because I removed the shifter mechanism and I'm not sure if I'm in gear or not.

So, yet again I haven't gotten it running. Pretty sure a V8 swap would be running a lot faster than this junk.
It's one thing after another with this thing and I'm getting frustrated.

You have no idea what to do next?

Tomorrow I'm trying to start it with ether since I have no means to tow start it. I'll pull the glow plug fuse to be safe. I just find it weird the glow plugs won't work now when they were fine before I tried the turbo diesel starter.
