Hey there, thanks for the question.

Both the injector pulse and spark are controlled by the distributor, not the cap or rotor but the actual optical sensor (cam sensor) inside the distributor itself. So unfortunately replacing the cap and rotor won't fix it. You need to replace the entire assembly.
