Hopefully someone can shed some light on this problem of mine because it would be nice if I could see my instrument gauges working. I have a 92 Subaru Loyale Sedan non  turbo Auto trans and My speedometer and tachometer work just fine. But, as for my oil pressure, motor temp, volt meter and gas guage they don't even move a little bit. I've pulled the dash out and checked all the connections and everything is fine so I don't know what else it could frickin be. Any ideas would be greatly appreciated. 

 CHECK THE 15 amp fuses.   Fuse box is behind a cover, lower left of the steering column.   There is one marked "meter" near the center.

I checked it and it's good. I pulled the fuse with the car running and the engine shut off so I know the fuse is good. And it's labeled (meter and engine).

 

I'm still stuck on what do do if anyone has any ideas? 

Try to find a wiring diagram and find the common denominator wire that serves those gauges.  beyond that you will need to start checking voltages and search for a possible wire break(s).
