Hi well the more I work on this 91 silverado 305sbc the more things are going wrong. I replaced the control module, plugs. magnetic pick up, rotor & cap now the dam thing wont start. There is no spark, & no spark from the coil, I held the coil wire above the cap terminal and nothing, hooked up a spare plug and no spark there. I used a test light and there is power from the plug that hooks up to the coil and I even checked the power leaving the coil going into the distributor and there was power there. I cranked the engine over and there was power to the coil lead while cranking but still nothing from the coil. So I just about ready to give up and take it to a mechanic maybe he can see something Im missing, anyone had this problem? Before I changed the cap rotor ignition module and magnetic pick up it at least would start now no spark. Help!!!!!!
