Truck won't shut off.

You should have a fuel shut off solenoid. Diesels don’t need electric to run.
Edit: it will use power to shut OFF, Im sure there is a way to manually override it

 

Turn the key to off position

 

I’m guessing fuel pump not shutting off, if I’m not mistaken isn’t that how diesels shut down? But cutting off the fuel?

If that’s the case then a simple switch or solenoid replacement for the pump is what’s needed or something’s wrong with wiring.

 

LOL

 

Yeah i would agree. I know when my truck turns off after auto shutoff . if i try to start it without turning key off then back on it wont start. It will crank but not turn over, i owuld expect it cuts off the fuel pump. I would agree thats probably what it is

 

I swear, this just gets better and better. If I'm feeling down and need a chuckle, just tune in to TTR for the latest. Can you imagine the horror, my truck won't shut off, what do I do?
And what the heck is this^^^. Should make it perfectly clear what's wrong,,,yeah right. Things were so much easier with the BC, just turn the screw on the pump or dump the clutch, that will shut 'er off.

 

Your lucky its not a regular car forums.

I personally recommended someone deflate their tires because the lights wont shut off.

 

I was wrong an E model doesn’t seem to have a shut off solenoid. Odd. If it’s an electric fuel pump it could be turned off but I would use caution.
Try the dash shut off switch I’m unsure as to the outcome. It’s kind of hard to help over the internet.

You really could choke it down (high gear brakes set dump the clutch) if it was an emergency but that’s hard on stuff.
