2004 F-150 Won't Start - Trying to diagnose

I have a 2004 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 (it’s fairly new from 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.

Shift the transmission into neutral and then try starting the engine.

If the engine starts, there’s a problem with the park/neutral safety switch.



Won’t start in neutral…

See if the 60 amp fuse in the under hood fuse box has blown.
