98 Ram 1500 5.9 wont shut off, key removed

Try swapping the ASD relay with another relay (fuel pump, starter, etc.) in the "under the hood" power junction box. Almost sounds like the ASD relay is welded shut. O' course this is a wild guess. But since the ignition switch has been replaced, the ASD is next in line.

Thank you for your recommendation, I have already swapped out the ASD relay. I just went out and tried It once again to be sure, no change. I pulled the steering column apart tonight and went through all the wires looking for anything loose or pinched. I double and triple checked all my fuses and relays and swapped them with others. Still when I put in the 50 amp fuse labeled “battery” Witj the trick off It starts dinging as if the keys in the ignition and my abs and one other light comes on.
