If you somehow inadvertently installed the rotor incorrectly, it would not only probably not start, but would likely break the rotor and/or distributor cap as well. If you removed the distributor cap completely when you removed the rotor, verify the spark plug wires are in the correct order. Since the distributor cap has some internal crossovers to route the wires to the appropriate sides of the engine, connecting the plug wires can be a little confusing.
