I went to start the truck today and the glow plug light didn't turn off in the normal time frame. I turned it off waited for a bit , I went ahead and started it , it eventually went out after 15 seconds of running but then would come on for a few seconds shut off and then repeat. What do you think it is?
What You are describing is pretty much normal. That's how the Stock GP system works. Your going to get a little longer glow time whn temps get colder. Then the system is going to 'AfterGlow'. Meaning it will light the plugs on, then off, for up to 2 minutes.
