Will not start there is no power to ECM/Ignition fuses but power to other fuses

My truck will not start due to electrical issues. All of my fuses under the dash appear to be good but I'm not getting voltage to the ECM-IGN fuse and a couple of others. I had just fixed a wiring issue with my headlights and now those work, but my truck won't start. Did I maybe blow the main fuse that's for ignition? Looking for a wiring diagram from the battery to the fuse block for the ECM fuse.
