Start with any fuses.
There should be a power relay for the computer as well. Mine is next to the computer behind the passengers kick panel, not sure about an 89. The panel tho is held in with a plastic push pin and partially by the sill plate. Relay looks like a 1x2 inch black cube on mine, seperate from the computer. Sometimes you can hear it click when you turn the key.
Check the wiring up front on the starter solenoid on the fender (behind the battery) for anything loose or corroded as well.
Check the stickies for wiring diagrams.
