Why would shifter lock up and key not removeable from the ignition

"items marked 201 to 215"
are not relevant to this issue.

As for "keep the key locked into the ignition",
the idea is that it's always a good idea to be sure
that the vehicle is in PARK before removing the key.

Ok sounds good.

See that's what i meant about a company assuming that humans are dumber than they are. Apparently they want to force the person to check the shifter to make sure it is in park, i guess, even when there were millions of cars made without that 'feature'.

I assume now that the shifter locks the key in the ignition if it senses that the shifter is not in park.
Would you happen to know how it senses that?

My original problem was the car stalling out and not starting again, and at the same time the shifter could not detect park. The two must have something in common because each started at the same time and ended at the same time. Could it be some electrical problem that is common to both.

Thanks.

Cars have interlocked these mechanically since the 60s ? You don’t want people pulling the key on a steering lock car while driving, obviously

Oh that's interesting this is the first car i ever had that did this. My first car was a 1964 and i had multiple cars since then. Maybe they were not as advanced? None of them had OBD-anything (ha ha), no computer.

But anyway, the question was what makes the shifter detect it is not in park. I guess it is a switch of some kind? Maybe the voltage from that comes from the same place the fuel pump voltage comes from (or something like that).

I have some interesting news though on the fuel pump i posted in the other thread. The most interesting measurement was that the signal from the ECU to the fuel pump relay is a square wave 41.6Hz and 50 percent duty cycle. This matches with the schematic so far that suggests the signal must constantly keep triggering the circuit in order to keep the pump running. More in the other thread.
