92 7.3 idi wont start cold, I’m not getting any current out of my glow plug connections. Jumped the controller and it didn’t even spark, checked wire from battery to controller and there’s plenty of power just somehow it’s not going passed that. Even wired up a switch all it does is click once when pushed and that’s it. Not drawing any power either. Just to double check I pulled a wire off a plug and grounded it to see if it would spark and nothing. I also think I have a fuel issue because while I’m cranking there is no smoke coming from exhaust. Only thing I get is a little from the intake after I’m done cranking it. Plugged it in for a few hrs wouldn’t start. Cranked for a full battery depletion. Waited about 5 minutes gave it another go would fire instantly. It’s just not making sense to me. Is it a fuel issue? Could the plugs be related to a safety switch of some sort?
