No spark

the CPS (Crankshaft Position Sensor) is a common reason for no starts. Sometimes the connector loses its connection. I would unplug it, check for corrosion on the leads and plug it back in with dielectric grease.

The crankshaft position sensor is mounted to the transmission bellhousing at the left/rear side of engine block

before you replace the computer have the crank sensor replace it is located between transmission and engine by the driver's side on top of transmission
most likelly your computer is ok
the distribuitor has nothign to do with spark on this cars
