Hi, there should be a fuse and a Starter Relay located in engine compartment, driver side, front side of strut tower, mounted in relay block on fender wall.
Different manufacturers use different abreviations for circuit fuses and relays, I recommend to check all of them.
Also, check if when key is in RUN, power is getting to the Starter Selenoid Mounted on top of the Starter thru the skinny wire (There is a FAT wire coming straight from the battery, that one is HOT at all times,) if power is coming in, REPLACE STARTER SELENOID, if no power present, REPLACE IGNITION SWITCH.
I've includded a troubleshooting chart, instruccions on how to replace STARTER SELENOID and some pictures to help you better identify and fix your problem. (I always think is better to have too much information than not enough) : )
Four types of starter motor are utilized depending upon the vehicle transaxle and assembly plant location. Manual transaxle equipped vehicles utilize a conventional starter motor which consists of a yoke, an armature assembly, an overrunning clutch assembly, a solenoid, a commutator end cover, a brush holder and a pinion drive lever. Automatic transaxle equipped vehicles utilize a reduction type starter motor which has, in addition to the components found on conventional starter motors, a reduction gear and shock absorber assembly.
In the basic circuit, the solenoid windings are energized when the ignition switch is turn to the START position and the clutch start/neutral safety switch is closed. The resulting plunger and shift lever movement causes the pinion to engage the engine flywheel ring gear. This movement also causes the starter solenoid contacts to close
With the contacts closed, the starter solenoid provides a closed circuit between the battery positive terminal and the starter motor. Because the starter motor is permanently grounded to the engine block, the circuit is complete and cranking occurs as soon as the starter solenoid contacts are closed.
When the engine starts, the pinion is designed to overrun and protect the armature from excessive speed until the ignition switch is released from the START position. With the ignition switch released, a return spring in the solenoid assembly forces the starter solenoid contacts open, breaks the circuit between the battery and the starter motor, and disengages the pinion. To prevent prolonged overrun, the ignition switch should be immediately released upon engine start-up.

Testimonial: "thanks so much"
SOURCE: I'm working on a 97 geo prizm and need to find the ignition relay,I rplaced the ignition switch and have no power getting to the switch,there is power at the harness and I can bypass the switch an
If you can jump it at the switch and get it to start, then the ignition relay must be working. It is hard to tell from your post but I think you are using power from another source to do this? I am thinking you have a blown fuse on the wire the furnishes power to you ignition switch.
