She is trying to turn over.... on 1996 Nissan 200SX

She died the other night, I've changed the distributor cap & rotor. Its not the battery, and does not seem to be a starter or alternator. Anyone know much about the timing on this car? i know the chain is old but as far as I know it has not gone yet. Car has 237,XXX miles on it.

Not sure why it's not turning over but if the car sounds like a "diesel bus ", then I suggest getting the timing chains replaced. Had mine changed at 231,000 miles. My Nissan 200sx had 2 timing chains. Good luck...
