Car cranks but will not start, no spark and the rotor is not turning.

Timing belt has either lost tension, broken or the teeth are stripped off the belt!! It turns the camshaft which turns the distributor! Or is supposed to if the belt is ok.

that vehicles camshaft has a high tendency to break right in the middle. the oil passage on the cylinder head welds shut from heat, then the cam no longer gets oil at that location. the camshaft breaks, so your timing belt that is good, spins, but the distributor does not. this also tells me that your vehicle had a blown head gasket not that long ago, it is heat that caused the problem.
