Fuel Locking the cylinder
I have an 03 early build 6.0. It lost one injector at all times and was skipping on two when cold. I replaced all three injectors, 3-2 and 8. Started good. Ran about 4 miles and felt like it ran out of fuel. Stopped and restarted. Ran quarter of a mile and did the same thing. This time motor was locked solid. Pulled codes found 1 and 7 contrib codes. Assumed new injector on that side was at fault. Pulled injector, still solid pulled 1 and then 5, boom cloud of fuel.
Ran for about two mins and same happened again. Pulled 1,3 and 5 no fuel. Pulled 7 no fuel obvious but lock gone. Got supplier to swap out new injectors. Refit same again !
Help what is going on. Going to replace 7 tommorow as a long shot. I changed all seals each refit. No fuel in oil or coolant. Does not lock till truck has ran for a couple of mins.
Found out the problem is an injector cup. I hope !

Love my truck, but hate the reliability. Love the look of the 2011 if its RELIABLE
