225 Slant Six Crank but Won't Start (Fuel but No Spark, Dist. Rotor turns)
The points open and close so depending on where the engine is stopped they may be open or not. You should be able to observe this by watching them as you crank the engine. To crank the engine from under the hood, jumper the two large exposed terminals on the starter relay with a metallic tool such as a screwdriver.
Also, with the light on the coil NEG terminal and the key "in run" cranking the engine should cause the light to go on / off. If it stays either on or off, "on" in your case, you have found the problem..........bad points.
By the way, leaving the key "on" with the engine not running can "fry" the points.
