with respect to your background.
would turn over??
using the starter or using bar to manually move the engine?
is the tranny in neutral? wheels off the ground?
I'm these might seem simple questions but not answered in your post. and they make a difference.
why
tranny locked..engine tear down..not needed
tranny in neutral but cannot bar the engine over manually..hum!!! broken rockers..glow plug..something jambing the engine..tear down needed
not turn over..dead battery..weak battery..key switch problem..
-just some thoughts. from some who like to take things one step at at time...
