Do you have a mini starter?
If you disconnect the slide-on connector on the solenoid and it keeps cranking, the solenoid would seem to be latched.

New doesn't mean good, and a weak battery can wipe out a solenoid in one cranking episode.

you could also try disconnecting the control wire for the circuit. Maybe it is shorting to another power source somewhere and causing it to stay on. Try disconnecting it and see if the problem goes away. If it does then your control circuit is continually getting power from somewhere. I had this problem and it turned out the wire was cracked right where it goes into the harness and was rubbing next to a fusible link. Worth looking at

I had the same problem and it was the rod inside the column sticking. You turn the switch and pushes the rod down to power the solenoid and it stays. Did you change the actual ignition switch or the lock and tumbler?

If you have a starter without a piggyback solenoid, change out your fender solenoid. When you pull the old one, test between the normally open and common terminals. It probablywill show very little resistance.

If you have a piggyback solenoid on your starter (you never mentioned if you do), you gotta do one more test to see if it's the piggyback or fender solenoid.

My car did the same thing a few months back....the starter got hung and fried the solenoid before I could disconect the battery.
Did you replace the starter too? I had to replace the starter and the solenoid..

Good luck

Just a thought, i know its not on a mustang, but Ive had a starter stick on my 63 galaxie back in the day. The the rod that the bendix slides on had a bur on it and somehow stopped the bendix from kicking back into the starter housing, what a horrible noise that made.

Like i said, this may not help, but then again it might be the problem by some random act of god.

Been there done that.Pretty embarrassing when theres people around and you have to pop the hood and beat the solenoid.

I too am looking for a fix to this problem, except mine will go ahead and dis-engage if I put it into drive or reverse, still does it when I put it back into park or neutral though.

Look for an issue coming from the ignition switch (not the solenoid). The neutral-safety switch allows power from the starter interlock circuit to pass while in P or N but interrupts it when any other gear is selected.
