Random No-Starts

Sometimes a coil will fail intermittently when they're on their way out. You can check the health of your coil with a multimeter.

From Chilton manual 26608: (the resistance readings are for a stock coil)

Primary resistance: Disconnect the wires from the coil and connect an ohmmeter accross the coil primary (low voltage) terminals. The resistance should be between .8 and 1.6 ohms. (see illustration)

Secondary resistance: Now connect an ohmmeter between the negative primary terminal and the secondary terminal (the one that the distributor cap wire connects to). The resistance should be between 7.7 and 10.5 k-ohms. (see illustration)

Ignition coil primary winding to case resistance: Measure the resistance from the positive primary terminal to the case of the ignition coil. It should read about 10 M-ohms.

If any of these test otherwise, the coil should be replaced. Hope this helps
