troubleshooting 90 4runner no spark

Parked the runner after a desert cruise. Went to start a week later, did not start (would crank) and started diagnosing. No spark at the plugs, no spark at the distributor, no spark at the ignitor. Tried to jump the plug to get a code reading, producing no codes to read. Replaced the Ignitor and Module.
have OHM out the plug wires
Have checked fuses and relays.
Have checked grounds
Anyone have any ideas?

 

What engine?

thank you let me run through that and see where i am after working that diagram

 

on my rig, when I was faced with this issue, it was the distributor. It is where the ECM gets the signal that tells the program how to send the spark from the ignitor. Do you have a check engine light when the ignition switch is on but not trying to start? If so, the
ECM is not dead...
