glowplug confusion

I quick question.

Haveing issues with starting and air leaks.
I have done troubleshoots on the "Controller" (what the GP's are wired into) and come to the conclution that that needs to be replaced.
Question is, whats the difference between the GP controler and GP relay?
what are troubleshoots I can do on the relay to determine if it needs to be replaced.

Starting issue can be read here if interested. http://www.oilburners.net/forums/showthread.php?t=33324

found wet return lines, which I am contributing to the air intusion, any other common air intusion places to check?

Thanks.

Oh I see, so the relay is ontop of the controller?
and the unit as a whole is refered to as the controller?
well, one of the terminals on the relay broke off so I'll need a new one of those.
Anyone have a part number? motorcraft only? dealership or parts store?

Thanks

I got mine from a parts store. It's not dealer specific. Just pull yours off and take it in with you. I think mine was about $12.
