ktmlew Posted September 21, 2005 Share Posted September 21, 2005 Got a 2003 F550 that shows a prod date of 04/03 and has a 6.0L. What month was the "introduction" of the 6.0L? I'm asking because it has seven PCM codes with intermitant CEL. When moving FICM harness just left of fuel filter housing engine misfires so assuming harness is damaged by intake bolts. The 05S34 "program" was supposed to cover prod dates after 09/03? They only list one part # for the FICM harness so don't guess it matters just curious? I can't remember when the 6.0L was released? Am I just having a brain-fart here? Quote Link to comment Share on other sites More sharing options...
Torqued_Up Posted September 21, 2005 Share Posted September 21, 2005 That is a good trivia question since model year productions typically begin with the ninth or tenth month of the previous year but now that you mention it. I have never seen a 6.0L truck or a 6.0L engine build date that was in 2002. I have seen quite a few 2003 trucks with the same old harness issues. I just use the harness listed in the recall and add some conveluted tubing to the FICM connector take outs. The harness already has that plastic collar and caps on the connectors.
