OM642, Crank, No Start

[Davsha]

Greetings,
I previously posted about a rod knock, on this engine.
Finally, I got around to changing the #3 rod bearing, with engine in vehicle.
I accessed thru the lower oil pan & broke away enough of the plastic oil baffle to have clear access to #3 & #6 cyls.

The bearing for #3 was COMPLETELY missing. Hopefully that alone, accounts for all the metal shavings & copper powder
in the oil pan. I changed the oil 2 x, after turning her over & cleaned what was possible. Also torqued down on #6
which had light play. The upper & lower shells are still intact .
Did not use plastgage bc i expect that nothing is true& there's nothing I can do from underneath.
Surprisingly, I found no gouging on anything visible & no sign of oil starvation.
Which leads me believe that perhaps a bad injector on #3 could have overstressed this cyl?
I did have a stored code at 1 point. No longer have the code #.

My current dilemna is that I'm trying to start her to see if the knocking improved at all.
But same pattern everytime.
Cranks over weakly at 80 RPM & cuts off after exactly 5 secs.
Tried cycling the fuel pump with key. Did not yet try bleeding as I'm not sure it'll help.
It DID run dry of diesel at 1 point according to my code reader, but now has 2 gallons.

As always, any insight is welcome.

I think that minimum crank speed to start an OM642 is 200 rpm....so 80 is a long way off. Flat battery?
No offence...but by what you have said about the repair I'd be amazed if it doesn't still rattle/knock.

"Also torqued down on #6 which had light play".....hmm.

I would be more than amazed, No 3 shells missing

If you watch pretty much any of videos on the "I Do Cars" channel on YouTube you'll see that a disintegrated bearing usually trashes the inside of the engine. I expect that any time and expense that you're throwing at the engine now is a waste of time. As for it now failing to turn over fast enough to start, the new/tightened bearings are probably too tight for it to turn over freely enough.
