I am just now reading your reply. Somehow I missed it last month. Sorry. Did you get the engine going? Previously, I borrowed the special CAT timing tool, and that was about three years ago, so I don't recall the specific TDC relation for the timing procedure. But using the tool gets you going in the right direction. Hope everything turned out all right.

A special timing tool is necessary for that engine. We run a few 6.6 engines which are the 6 cylinder version of the 4.4. I'm guessing the gear to the high pressure fuel pump spun, thus causing a timing issue. That gear is secured to the shaft with a press fit and bolt/washer; it is not keyed. The cam position is read by the ECM via a sensor on the fuel pump. If that gear has spun, then the ECM will read a timing issue between the cam and the crank.
The front cover must be removed, and if I recall right, the coolant must be drained to access the timing gear to utilize the timing tool.
