Gas gauge seem to not be reading correctly anyone know how to troubleshoot this how can you tell if it the gas gauge itself and not the fuel sending unit.
Anyone here know if all the 1999 and up mazda protege and mazda protege 5 all have the same fuel sending unit as if they would all bolt up the same way or are they any different I'm pretty sure they should be all the same just wanna check here first before I pick up one at a junk yard thanks.
