[Public-list] Why , oh, why won't my glow plugs glow?

If you have access to a volt meter check to see that you get
full voltage right at the plug.  When you said that the
solenoid clicks but does not connect fully indicates that
you may have low voltage to the engine.  The common point is
the neutral (ground) to the engine check this carefully
befor you purchase anything.
