Your car could have a 1.6 or 1.8L engine. Cranking over the engine does the rotor rotate (ie does the cam shaft turn timing belt in tact ect....).
With the ignition key on you should have power at the Black / Orange wire at the distributor, with that electrical connector disconnected from the distributor. Plug it in this powers the positive side of the ignition coil and the ignitor assembly within the distributor. The ignitor assembly grounds the ignition coil at a frequency to saturate and trigger the ignition coil. The coils fail relatively often. If the rotor itself melted was the distributor seizing up, this was a common problem on older Hondas.
change the crankshaft position sensor located by the bottom pully. You'll have to pull off the front passenger tire remove the plastic shrouding. Its right next to the oil dip stick tube . When this sensor goes bad and they do you will not get any spark to your distributor. For this car Geo Prizm 1995 1.8, it cost around 85.00. Careful when you pull the old one that it does not come disconnected from the wire housing, you'll have a heck of time getting it out. There is no room to work.
