EAsy , remove distributor cap then loosen two screws holding rotor down and pull it off . reassembly is reverse of removal
Unscrew the screws holding the cap and lift it up and away from the distributor. Pull the rotor straight up and install the new one.
The rotor button is inside the distributor cap.
Change spark plugs and wires, change all fluids, check o2 sensors, distributor and rotor cap possibly, change all filters...and a fat wallet...

On a 1995 Chevrolet Caprice Classic, the distributor cap and rotor are located on the front of the engine, typically near the intake manifold. The distributor is mounted on the engine block, and you can access the cap by removing any obstructions, such as the air intake duct. The rotor is situated inside the cap and can be accessed by removing the cap itself.
unbolt the distributer cap and lift up. The rotor is under the cap on a pivot. It should just pull off. Keep track of the position of the rotor and distributor cap though. Just in case.
did you replaced spark plug also distributor cap and rotor???
To remove the distributor rotor on a 1995 Honda Civic, first, disconnect the negative battery cable to prevent electrical shorts. Next, remove the distributor cap by unscrewing the screws or releasing the clips. Once the cap is off, gently pull off the rotor from the distributor shaft, being careful not to damage any surrounding components. Finally, replace the rotor if necessary and reassemble everything in the reverse order.
unplug battery, pull on the distributor cap, remove distributor rotor, slide out dust cover, pull 4 Phillips screws that hold coil in place, remove wiring, replace reversed of removal.
To remove the distributor on a 1995 Toyota Previa, first disconnect the negative battery terminal to prevent any electrical issues. Then, remove the ignition wires from the distributor cap, followed by the cap itself. Next, unbolt the distributor from the engine block and gently twist it while pulling upwards to detach it from the engine. Be sure to mark the position of the distributor for reinstallation.
The spark travels from the coil to the distributor then from the distributor to the plugs. So if you have spark going into the distributor but not coming out to the plugs, I would blame the distributor cap and rotor being at fault.
