Are you sure the issue is no spark and that you have adequate fuel pressure and the injectors are firing? Are you sure the issue is no spark and that you have adequate fuel pressure and the injectors are firing?

First you should double check that each plug and coil wire is "clicked" in.


Here's how the ignition system works.
You turn the key, the coil is powered, the coil in turn powers the distributor cap, as the engine rotates the rotor is turned, which powers the wires and the plugs.


So if you have power to the coil, just replaced the cap and rotor, good wires, the plugs could be bad, but I doubt that they would all go out at the same time.


That being said, the timing belt must have snapped, as this is what makes the rotor turn to fire each plug.


Here is one way to verify if the belt snapped. Remove the distributor cap, and push aside clear from any moving part. With the cap removed crank the engine over and watch the rotor, if the rotor doesn't rotate, then your timing belt has snapped. Or you can remove the timing cover.
