could be the starter motor has siezed on. Not that unusual on older cars

if so leave the car in3rd, ignition off, and just try to push/ move it a little, just enough to move the transmission/engine/starter.

Try to start normally.

On some cars there was a large nut on the end of the starter that you could try to turn if you had this problem, but Im probably showing my age.

its not in good condition, no, but will power the lights, but the engine wont even turn over, not even a hint of it.

That means very little, the lights may well work, but when you hit the battery with starter motor current the voltage just collapses, I,d say this is the problem
