You said you checked fuses in the dash then all of a sudden no more starter
I suggest you look closely at your dash fuse box and the 04 sport fuse diagram
Make sure you put the fuses back in the correct spot if you pulled them
There are a few blank spots that you can stick a fuse in but there are no wires there
Something to check
Also these trucks have a starter relay in the under hood power distribution box
If that relay goes out or has any wiring issues then the starter will not crank
Multimeter should be used to check for good power at the starter itself, also check the signal from ignition switch to the starter, when the key is turned to start you should see battery voltage at the small wire. If you do then likely a bad starter
If you don’t then likely a fuse or starter relay issue
I’m sure is has been covered here but the theft light should go off when cranking the
