Is it possible 4 the timing chain to break while drivin & is that all it may be?

What is your question?

My car stalled while I was driving down the road. I replaced fuel filter, spark plugs, crank pulley ( which was actually popped out & not in line with other pulleys) & sensor & removed & cleaned fuel injectors. Someone finally told me to pull the oil fill cap & watch while trying to start car. If nothing moves, it's the timing chain. I checked & there was no movement so I'm getting ready to tear down the engine to get to the timing chain & I just want to make sure that's all it could be before I go thru all this work & have to tear down again.
