You need to measure the coil's primary and secondary resistances See below specs. If okay check the distributor pick up coil and then the ignition control module

IGNITION COIL PRIMARY RESISTANCE
Tips Click a link to view tip
Tech1Tip: NO VOLTAGE TO COIL OR ECC RELAY

With ignition switch in "OFF" position, disconnect ignition coil connector. Inspect connector for dirt, corrosion or damage. Measure resistance across ignition coil positive and negative terminals. See Fig. 4.
Resistance should measure.3-1.0 ohm. If so, ignition coil primary circuit is okay. Proceed to IGNITION COIL SECONDARY RESISTANCE test. If resistance is less than.3 ohm or greater than one ohm, replace ignition coil.

IGNITION COIL SECONDARY RESISTANCE
With ignition switch in "OFF" position, disconnect ignition coil connector and secondary wire from coil tower. Measure resistance between negative coil terminal and coil tower. See Fig. 4.
Resistance should measure 6500-11,500 ohms. If so, ignition coil is okay. Proceed to WIRING HARNESS test. If resistance is less than 6500 ohms or greater than 11,500 ohms, replace ignition coil.
