i have a 2006 cummins auto, today i went to town and when i got there i shut the key off but the truck didnt turn off. the key came out and the truck still is running. i have no dash lights or gauges as if the truck is normally turned off but its not. the radio stays on tho when the key has been turned off and the door has been open. i pulled the diesel pcm fuse to kill the engine. i put the fuse back in and tried it again but all is still the same. when i pulled the fuse tho and the engine died i did hear a ticking noise behind the drivers side headlight as if maybe a relay was sticking. i cant get that to happen every time tho. any and all help would be great! thanks

 

Come on guys any help or input is needed!!! Anyone?
