OK,
Check that there is 12 Vat the Pos side of the coil, take off the distributor cap and check that the points are not closed up, turn the engine till the lobe on the points cam open the points, if the points look burnt replace and re set the gap, check the carbon brush in the center of the cap, it rubs on the rotor, also check that the distributor shaft is turning with the engine, start here.
