Yes there is an audible alarm in the dash for oil psi, voltage and engine temp.
To test fuel gauge, access fuel level sender, key on, remove pink wire and ground it, the fuel gauge should peg past full if not test at gauge itself eliminate wiring, if gauge moves then a bad sender if doesn't move bad gauge, with the sender signal wire(pink wire) disconnected the gauge should read below empty. Same test for oil psi gauge except its a light blue wire(iirc).
