Replace distributor 'assembly'..... The distributor is what makes that single ignition coil produce spark!!!! The coil can't do a damn thing until the distributor tells it to!!! IF you don't understand, find a MECHANIC and get some hands-on help!!!

ok so if the computer controls the electronic spark control module that sends a signal to the coil which then sends the signal to the distributor but is not happening at this time the distributor is still the issue i dont have a coil pack i have a single coil that sends the signal to the distributor!!!!!.....so replacing something after the dead spot will give me back the signal
