Was driving down the road cruise set and truck just died. It was about 4 degrees so just assumed it was gelled fuel. Treated the fuel and changed filters now it wont start. Had it towed to my shop to sit inside overnight. cycled key countless times now and still no start. When cranking over it will crank for about a second then catch almost like hydrolock then it moves past and does it again. Now I noticed raw fuel coming out of the exhaust pipe. No codes or check engine. Not sure where to go from here other that dealer and really dont like that idea.

Any suggestions would be much appreciated. Thanks

You got problems.

If raw fuel is coming out the tailpipe during crank I would guess you have an injector that is pissing fuel out.

Pull all glow plugs out and crank the motor over to identify what cylinder is filling with fuel.
