I replaced the fusible link and now my car has no power whatsoever and I get just a humming sound from the engine when I connect the battery.

Did you have no power when before the link was replaced? If so, fusible links go out when something major has shorted like the alternator. I would try to disconnect the wiring to the alternator too if it changes and stops the noise. Here is information on the fusible link Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.

The car was running great before I replaced the fuse. I only replaced it because when I was changing out my battery, I accidentally bent the face and it broke off. So, I don't know if maybe that would have caused a short somewhere or not. If so, where would it have shorted out at?

Here is how the power is distributed throughout the car and a guide to help you test for power, but you could have shorted out the IPDM which is common. Here is the unit location and how to replace it in the images below.

I have replaced the IPDM, and every relay you could possibly find on the vehicle and replaced them. But I still have the same issue. My power seats work and rear brake lights but nothing else. Found The humming sound is coming from the ABS. Any possible ideas what could be the next possible issue?

Is there a chance the ground cable is not connected to the engine block and car body? Was there a small negative cable that is not connected?

Okay, when I use a fuse checker on the fuses in either fuse box, I get no power, yet every fuse is good. And the battery is good because the ABS starts humming when connected. Why would my fuse junctions have no power to them?
