Have one cylinder that has an ignition miss, it is not the coil pack have changed with another cylinder and the coil works fine, could it be the transitor pack or could it be a bad connection somewhere? This is on a 90 300zx non turbo

well we have established which cyl is missing. remove the plug, and ground its threads on the plenum, start the car... do we get spark? if yes, continue onto the injector connector for thta cylinder. does it look green? clean it... fix problem? no? ok get the car cooled down 100% and OHM test that injector. report your findings.
