Edward, if you put a test lamp to the coil (low tension) that goes to the distributor then crank the engine, the lamp should flash intermittently, as if make and break. If it is constant then I suspect it is the electronic ignition module that is at fault. http://www.vehicle-electrics-online.com/index.php?page=shop.product_details&flypage=&product_id=9301&category_id=540&manufacturer_id=0&option=com_virtuemart&Itemid=35.
