UPDATE:::::

I received my new glow plugs yesterday and started to get to work on my 86 300sdl. Number 6 was definitely bad. I replaced it and then checked my resistances with my ohmmeter and all was well except for Number 3 now.
When the old plug was in on number 6, the only resistance that was off was number 6. I replaced number 6 and now all were fine except number 3.
I replaced number three (intake manifold on ) and then checked reistances again and all was well. I turned the key, glow plug light on, waited for it to go out ( 16 seconds at 52 degrees outside) turned key to start and it was WONDERFUL!!! Success!!!!

While I was at it, I replaced my plastic clips that hold the hard fuel lines to the intake manifold. They were crispy and crunchy and melted in my hands.

Took it for a test drive and damn... a vacuum leak somewhere. Shifting really hard. Looked under the hood and I dislodged a vacuum line to the blue flying saucer. Hooked it up and all is well.

Tomorrow morning it should be about 38degrees out. We'll see how it works then.
