Well, you know the ignition coil has to be good. then the ignition control module inside the distributor has to be good. It controls the ignition coil firing times. This module can be tested at a parts store. And then, also in the distributor and attached to the ICM is the pick-up coil which tells the computer crankshaft position, so the computer knows when to signal the Ignition Control Module that it is to cause spark out of the coil. These are the components of the ignition system, so you know how to check them. Ignition coil, ICM, pick-up coil, and the pcm, computer.
First, check that power is getting to the coil when the key is turned to on. The coil must have battery voltage applied to it before it can cause spark. If there is power there, test the ignition coil, test the ICM, then the pick-up coil. If your wiring is good, one of them components may have failed. And of course, the last thing to suspect is the computer, the pcm. Hope you don't have to get that far.
