You need a spark tester to establish if you have spark at all. Don't just pull a plug and look for spark by grounding on the head or something.
And a coil test somewhere.
From memory: no guarantee
Ignition module is suspect. If installing a new one, they have heat grease included (or ask the parts man) to spread on or you'll be putting another on soon.
(Not the pickup coil by the way. If that was bad, you would not be getting either fuel or spark)
So from the pickup coil, the ignition module provides the reference high signal for fuel, but in this case more significantly, is also the on and off signal to collapse the coil based on the pickup coil signal. Sometimes only one side works, explaining the injector pulse, but no spark.
PS: I think these had a powder metal reluctor in the distributor which used to crack and shift on the shaft, but that's probably not the issue here
I think and hope.
