Depending on year it can be in transmission or under the dash on your stearing column. I know the AOD's and C4's where internal was plug on left side of trans had 4 or 5 leads in it. .
Possibly a neutral lockout switch, possibly a bad connection, possibly an ignition switch.
sound like to me the starter solenoid is stuck the reason it does it in park is the neutral safety switch replace it and it should be fine
There are several things that can cause your brake light fuse to blow and keep your 1994 Ford F3 50 locked in park. The most common cause is a malfunctioning neutral safety switch.
The 2003 Ford F3 50 air conditioning clutch relay switch can be found on the firewall in the engine compartment. The air conditioning clutch relay switch will be on the passenger side of the firewall.
on the side of the dash

buy a new starter switch. WAIT! I had the same exact problem and replaced the solenoid with the same result. It is actually the neutral switch not making contact when you are engaging the clutch. Try pressing the clutch down really hard and it may start. Or better yet, just adjust the contact switch towards the clutch and you have fixed the problem! Unless the starter switch is the same thing the mechanic that told me it was a neutral switch
