I'm with Augie, I'm going with bad glow plug (even though it's new) or a dead battery in your glow starter.  First thing I'd do is take the glow plug out, cup it in my hand so you can see if it's lighting and touch the glow plug starter to it to see if you're getting any fire.  If you are, my second guess would be something wrong with your fuel tank if you're not getting any draw.... maybe a pin hole somewhere.
