Run a jumper wire from the positive battery terminal to the + side of the coil---pull a plug, lay it on the manifold so its grounded, (with plug wire attached) crank motor over---you should have spark unless you have bad points or coil. ---make sure the car is in park or neutral.---if car starts, ya gotta yank that wire to shut it off----don't walk away and leave that wire hooked up---thats same as leaving key on, and could start a fire.
