Before you pull your hair out try replacing the module on the left side by the headlamp. That little black thing amplifies the signal to the coil to make a spark in conjunction with the ECM. Living in Maine I used to keep a good used one in the glovy just for incase. The hall switch can be bad also. Take the dist. out with it still conn. and turn ignition on. Spin the dist. over and check for spark. If there is no spark do the scratch test from the conn. that will produce a spark, if no spark then it is the module. Hope that helps.
