What does your dashboard ammeter say?Turn on the ignition without cranking. You should see three amps discharge on the standard six volt ignition system. The reading may vary a little with a twelve volt, but will be in that ball park. No discharge? Points are not closing properly, are bad, or there is an open in the coil primary or elsewhere in the system. If you see the three amps dishcarge, crank while watching the ammeter. It should fluctuate as the points open and close. No fluctuation? Points are not opening, are shorted, or there is short elsewhere in the system. If these readings check out ok, and by "no fire" you mean the fuel/air mixture won't detonate (as opposed to a no spark condition), the next step would be to check the fuel flow. If, however, these reading check out ok, and by "no fire" you mean no spark, the coil secondary and condensor are suspect. And you can learn all this INSTANTLY without touching a wrench or screwdriver. See how useful the dashboard ammeter is?
