get a volt meter setup, measure from the block to the screw on each glow plug. if you have 10 or so volts to each plug, they are working. if you have zero volts to the screw on the GP, then your relay under the dash or a wiring problem exist.
if you are getting 12V, to each screw, most likely the plugs are all bad...

measure and report back what you have.

+1 on the valve adjustment... it's important for compression!
