ignition problems 92 4.0

Jeep was parked for 2 months now I have no spark. Coil and distributer are fine. I had a obd2 zj a while back and did same thing, which was crank sensor. Does crank sensor on older obd1 engines kill ignition too? What else will kill your spark? All fuses are good. Help would be much appreciated.

No cam sensor. Crank sensor and coil are new, still no spark. Anything else to check before new computer? On the fence about putting v8 in this thing so I'm kinda tired of throwing money at 242.
