know what ha ha i had that same problem no spark you changed the cap and rotor you said. check the timing belt see if it snapped off trust me i changed everything in my prelude under sun ignition module complete tune up coil and the timing belt snapped no spark thats an inteference motor if the belt if off or snapped you wont get spark. if the timing belt is good the ignition module could be bad check the wires to see if its sending signal to the coil
