2014 ISX Starting Problem starved for fuel

May have discovered the problem. Stopped at B-Line in Sweetwater this afternoon for a PM. Told the guy what was happening and said if you find anything let me know.

2 mins later he called me and asked me to come look at my fuel filter. He asked me who did your last PM? I told him Rush Truck Center in Commerce City CO. He showed me the filter and it was black. And the fuel inside the reservoir under the filter was equally disgusting.

Those ******* didnt change my filter so it had almost 30k miles on it. Not that it’ll do any good but I am going to let them know.

Don’t know if this is the cause but im betting its one hell of a suspect. Will see.

 

Im going to keep an eye on it for sure.

 

Update: Had a second filter turning black only after 8k miles. Bought a filter. Put a clear bottle under the Fuel/Water separator. First thing out, coolant and quite a bit.

Since I have warranty I took to Rush. I don’t have the final diagnosis but the initial prognosis is Injector Sleeves. The idea is to get the warranty to replace the Head since the Cummins sleeve replacement doesn’t seem to be a permanent fix as they have ongoing problems. Will see where it is tomorrow, Monday.

Black filter: soot getting into the return back to the tanks and then of course coming back to the seperator.

Basically. A mess.
