Start the truck, go to shut off but engine stays running even with the key off. Changed the ignition switch already. Have to pull the fuel pump fuse out to shut off.

There should be NO voltage on that term key off that is what is pulling relay on and keeping it running. Is powered by fuse 10 which gets power from ignition switch. So problem with switch or connector. Was there any burnt terms on switch or connector? Wire is Light green/Violet

I checked the connecter and wire, nothing looks burned or shorted there. It is actualy #9 fuse, pulled it and still had power to the green/violet wire. The "idiot" lights are on also when key is "off". Truck wont start until I disconnect the battery and reconnect. But still wont shut off.
