More diagnostic info on the 460D

So my 460D up and died when I just got it started. Sounded like something bound, then bang, she let go and the engine died. Now it cranks over but won't start, doesn't even smoke when cranking.

I have removed the timing cover on the injector pump, the pump IS turning. I removed several injector lines from the injectors, it is spitting fuel here. I'm not exactly sure how much fuel it should be spitting or spraying, but it is getting some, I'm thinking its enough. Next thing I wanted to check was timing, I had a hard time finding the timing marks on the crankshaft pulley, but once I did, I went over to the injector pump to see if the lines lined up in the timing window. They do NOT! So I turned the engine over by hand until the lines in the injector pump did line up, this took a quarter turn of the crankshaft. once the injector pump lines were lined up, I took a close look at the crankshaft pulley looking for marks. Nothing there. It seems the engine and fuel injector pump are way out of time, is this possible?? I then took the cover off of the front of the engine in front of the injector pump. I could see the crankshaft gear and the drive gear for the injector pump meshing just fine, no stripped gears.

So, is it possible for this engine and injector pump to be this far out of time? If so, how did it happen? I would think the gears in front of the engine would have had to either strip or jump, I see no signs of that having happened. I also verified that the cam was turning by removing the valve cover and watching all the valves open and close.

Also, it still stumps me that it isn't smoking when being turned over, even if out of time, shouldn't it still smoke some??

I'm pretty stumped here, but not ready to give up. Any additional thoughts or help on what to check next???

It labored, made noise. Make sure valves are still timed. In other words, when on top dead center number one cyl, the number six cyl valves should both be tight. Intake just starting to open and exhaust just finishing closing. I have seen them engines keep running with a broken crankshaft, but if it depends on where it breaks to determine if it will remain in time or not. You could have a sheared key on injection pump drive but I doubt if you would hear any noise. With starter removed you can rotate engine back and forth to tell if all components are moving in sync.

check the 3 bolts in the pump drive gear in the front timing cover. there is a hub in there that can be moved inside that gear. my 560 had only finger tight bolts when i got it and fought it trying to get it started. it put it way out of time

It crosses my mind that the keys holding gears to shafts can shear allowing loss of timing. Has the sound of the cranking changed radically (other than not starting and o white smoke) between prior operational times and now? Jim
