Yes the light lights up when positive batt terminal to white wire connection tested

 

Awesome, sounds like the controller is doing it's job, replace the relay and it should work if the Glow Plugs are good.

Festus, thanks bud that did the trick she fires right up now, I kinda feel like a bonehead I thought it was an air intrusion in the fuel system and the trucks been parked for a year because I haven't had time to diagnose as I wanted to remove box to replace all return and supply lines anywho.. I'm back In business and tomorrow is opening day for bow season! Perfect timing thanks a million for your help

 

Awesome ... Glad I could help!

If I may make a pushy suggestion, ensure it has Motorcraft/Beru ZD9 Glow Plugs in it now that it's working we don't want any other brands exploding tips.

Personally, I would pull everyone of them and ensure that!

-Enjoy
