So on my 7.3 I did the manual glow plug mod a few years ago, really just needed new glow plugs but I left it because it was all wired nice in my dash. Recently sometimes I'll press the button and the wait to start indicator will come on from the relay, but I have a second led wired to the output side that is feeding the glow plugs and it won't do anything. If I crank the engine for a couple of seconds it will wiggle something and it works and the output side light comes on, I can stop cranking and glow for 5-7 and it's fine.
I know it's likely a loose wire, but if it's not and my relay just isn't "jumping" theres no sense replacing the controller, just the relay since I'm manual now right?
