Yet another glow plug question!!!

Ok i have a 91 7.3. Been real hard to start past few days. Replaced all the gp's today and still not better. Now i realize that the gp controler or relay are not cycling. Turn key on one click/clunk from relay then nothing. If i put a test light between gp and gp wire and it lights, does that meen that they shoud be heating?

Yes they should be heating if it has current to the glow plug.
Check the ground wire on the relay/controller.
Does the Wait to Start light come on?
