Well I just drove to work and parked the truck turned off the ignition and removed the key but she kept on running . What the @$%^. Put the key back in to KOEO everything is like it isn't runnig wait to start lights up radio kicks on glow plugs start to cycle. Turn it off and everything shuts off except the motor. I was starting to get concerned. did the key on and of a few times and it finally shut down. Then I restarted it ( to make sure it would) and it shut down no problem. I'm hoping its gonna start when I leave a 3 am. Any clue as to whats going on? The ign. switch is fairly new.
