Maybe this is odd, maybe not. A 2011 F550 gets dragged in. Customer states he heard a grinding noise, the engine lost power then stalled. Is a crank/no start.
I confirmed it cranks normally but does not fire. Had a low FRP code and ONE glow plug circuit code. Data logger shows FRP at FRP Desired. No problem there. Relative compression show 1,2 and 5 10-15% loss. Manual compression shows 12 and 5 all below 100 PSI.
By build date and the glow plug DTC this sucker meets the criteria for a long block as per TSB 12-11-11 for 18.3 freakin hours and I am already about 4 into it without the cab off.
So what kills me is Ford doesn't even want a tear down and inspection?
