The glow plugs will come on regardless of temperature, it just never shows you the light because it doesn't need them to start.
Check the relay with the continuity or resistance setting on your multimeter - apply voltage and check it's giving out voltage where it should be. Most have diagrams on top of the relay detailing the type and pin outputs.
Meant to say before, when you put the new glow plugs in i'd put a dab of copper slip on the threads and be careful not to over-tighten them.
