Let's just be sure here...
The glow plug relay stays energized for only 20-45 seconds. You should be using the test light at the glow plugs while a helper turns the key, or reach in, turn the key and count to 20 while you test. Any longer, and the relay is off and the tester will not light up.
If you are standing right next to the relay and it's quiet, you should hear a 'click from the relay. If you do, but the test light says you are not getting voltage on any plugs, the fuse is the likely culprit. They can develop a hairline crack but otherwise look OK.
If you don't hear the click, it could be a problem with a contact in the key switch or a bad relay.
Let us know how you're doing.
