I keep replacing a 40 amp fuse that is for my ignition. I have looked at all wires to the engine and to the battery no problems there. I am having trouble takeing the steering column apart but so far no wires that look to be problematic. What is going on? How to fix and find the problem.

That goes to the ignition switch and starter relay so try switching the starter relay with a like relay and se if that cures it if not it may be a bad ignition switch
