My voltage gauge and oil pressure gauge both stopped working at the same time on my 85's digital dash. This happened about half an hour before my fuel pump failed and left me on the side of the road. I'm pretty sure its the fuel pump because the pump gets voltage when cranking but no fuel comes out at the TB inlet fuel line. Does anyone know what could cause the gauges to die or if the gauges could be related to the fuel pump? And where could I find a wiring diagram for a digital dash? Thanks in advance
