You should have a +12 ign power wire connected to the resistor, it runs throught the resistor to the coil, you should also have a +12 start only signal wire on +side of the coil. Make sure you have both. Turn ignition switch to run , not start, check for power at the coil +side. It should have more like 8v due to the resistor... if it doesn't (seems like it won't), could be a bad resistor (not as likely, never seen a bad one in 20+ years), but more likely poor contact in the spade (sometimes a ring) connector, or a the IGN +12v wire is not connected.
