Pretty odd to have that many go out with a similar reading all at once. I'd suspect the wiring to the glowplugs first.
Maybe it's time to pull the valve cover and ohm the glow plug directly. Of course if you go through the trouble of pulling the valve cover, maybe you should consider having some glow plugs on hand since getting the valve cover off is the hardest part of the whole job.
How do the injectors ohm out between the two banks?

Im not sure i know what you mean by ohm out, i tested the gp's by dissconecting the plug going into the valve cover and the twp outside pins, and like i said the drivers side all ohmed out at .4-.5 and passenger side 1.1-1.2 . so does that mean the pass side is no good or are they all in allowable specs?

You're going through the same motions, just metering on another set of pins on the valve cover connector for the injectors. See the attached link. If the passenger side is also different for your injectors, it could be a UVCH wiring problem more than plugs.

You can even remove the glow plug from the motor and ohm the tip against the threads, but if you go that far, why not replace them?
