Sounds like starter or neutral switch to me.
There are no fuses on the firewall to my knowledge but there is at least two relays, one is the AC compressor clutch relay and the other is the starter relay.
Test starter relay first, assuming already checked the charging system and starter. ASD (Auto Shutdown Relay) can also cause a no-crank problem. Both of those relays have a fuse. Both relays and associated fuses are located in power distribution center (fuse box) in engine compartment, next to the battery. The cover labels the location of all fuses and relays. Unless you have no power for lights and radio, fuses located under dash are probably not causing problem for starter. If you find a blown fuse, you must find the source and correct to avoid continually blowing fuses.
The Starter Relay is located inside the PDC (Power Distribution Center) that sits inside the engine compartment on the passenger-side fender well. The PDC is a rectangular black box perhaps 12" by 3" with a lid that covers all the fuses and relays contained inside. The layout and identification of all the relays and fuses is located inside the lid. There is a larger starter solenoid that is physically on the starter motor itself.
