I was not having any starting issues. When I turned the Key the Glow Plug Light would not go one. If I cycled the Key again the Glow Plug Light would go on in a normal manner and the Engine would start normally.
I was not sure it this was a Glow Plug Issue or an Ignition Switch Issue so I decided to Pull the Glow Plugs check them and Ream out the holes.

I checked all the new Bosch Plugs acrossed the Battery and the tips glowed.

How, long did you test yours. The one in pic 2 started of with the whole tip glowing. The others started of with the tips glowing and the heat moved back from the tip. It may be that if they glow long enough the whole thing will get hot.

I was looking for a differance between the Plugs. And, other than the Plug that worked and went dead that the #2 was the one that was different. You can also see it glows at a cooler temp than the #1 does.

The Glow Plug Light Functions normal now so it must have been the Plugs causing the problem.
