Help Needed '11 350 Won't Start!

[eZAK61]

I used the remote start, the truck started, ran for maybe 15sec. then shut off!

I then went out to physically start it. Turning key to on, everything works as normal,
When I turn the key to start the starter runs (even after I let go of key) but does not seem to be
turning over the engine.

Any ideas????? I have the block heater plugged in now.

Got it Started! Block heater was plugged in for about 30 min.
It still didn't want to start.
Started up normal, then after a few seconds went to a low power type of run, for about 10 sec Then back to Shake Rattle and Roll

You didn't mention the temperature. Is it cold enough for your fuel to gel?

At the time air temp was about +18*F
Truck had been sitting for about 10 days prior
Air temp is about +8*F now.

I would maybe try some diesel 911 then.
I think power service red bottle.

Remove belt and make sure ac isn’t seized. Remember 11’s have bad crank bearings, and often seize the crank.

WHOOO!!!!! Did not know that! I hope that's not it!

She is running now! I think block heater and Diesel treatment helped!

Thanks all!
