2004 F-150 Won't Turn Over	Sign In

I have a 2004 Ford F-150 STX 2WD with the 4.6L that I inherited from my grandfather this past winter. About 2 months ago, it had a really hard time shifting out of park, so I left it neutral with the keys in it. This naturally drained the battery, so I would just jump it off once a week and let it run. I picked up a brake light switch from O'Reilly's recently but have not installed it yet to see if it fixes the shifting issue.

Anyways, about a month ago I tried to jump off the truck and got nothing. No ticking or clicking, no sound. None of my gauges dimmed (cabin lights did not dim either), so it didn't act like there was a draw on the battery. I went and got the battery tested (battery's from June 2019) and it turned out to be fine. I disconnected the lines to the battery and starter and cleaned the connections and reattached. Still nothing.

Does this sound like a bad starter to anyone? I tried knocking the solenoid with a hammer and still could not get it to turn over.

Any info would be greatly appreciated, thank you.

Quick read, sorry. I bet it's been forced a few too many time so Neutral Safety Switch is off. Try just nudging it toward R or D, from "N" this time for one more start so you can fix that is unknown until that either works or doesn't quite yet. WARNING! TRUCK COULD START AND MOVE SO BE READY FOR THAT OR HOIST REAR WHEELS OFF THE GROUND!

There are a couple of fuses in the circuit, a neutral switch and a relay to check out.

Here is the wiring diagram
