I have a 2014 L 4600. I put some deisel in it that I didnt know had water in it. I ran it about 10 minutes then tractor died. I notice the fuel filter had water in it. I drained the bad fuel, installed new filter and good fuel. Bled the air after it was running I noticed the tractor had a miss, loss of power and blows black smoke. I replaced one injector and cleaned the rest. Still no change. I cleaned the injectors again reinstalled, while reinstalling I botice the line going to the pucmp connector was lose. I tighten it up and restarted tractor it blew a lot of black smoke so I turned it off but the tractor would not shut off. I close the air intake off and it died. What can I try to solve this.
