Measure the ac voltage on the white wire from the distributor that goes to the tachometer during cranking. It should measure some significant voltage depending on your ac voltmeter characteristics. No voltage tells you that the spark module isn't pulsing the primary of the spark coil and this could be because of a defective pickup coil in the distributor, a defective spark module, or a defective spark coil. Call and find a parts place that can test the coil and the spark module. Use your ohmeter to measure the pickup coil in your distributor.

It could also be the ignition module that's in there also. There is no real way for you to test the igintion module though. Autozone can test those for free with a computerized machine. Remove it and take it to Autozone for testing if the pickup coil test checks out ok.

I used 86Pacer's instructions listed above when I had this problem and it turned out to be the ignition control module. Follow his listed instructions and you will most likely solve your problem
