Bruce makes a good point, one test for the crank sensor is w/ a DVOM, place it on ohms readout and test through the sensor, its only a good test if the sensor windings are "open" though. A labscope is necessary for further testing.
Can't remember if the '89 was distributor or DIS though, if its distributor then the ign module/pickup may be toast and DVOM testing again is sketchy, your local parts supplier may have a free module tester onsite and they may be able to help you there.
If its DIS then again crank or cam sensor may be in question. Its a tough call w/out some special equip!
