Replace fuel pump relay for sure (check owner's manual, or google it), Check inertial fuel shut off in L trunk. There are some other things, someone will probably chime in
Also check fuel fiter not sure if a 1984 is fuel injected or carbureted if fuel injected filter is down underneath car on frame rail by right rear tire, if carburated it is either in carburetor by gas line or in the the gas line just before carburetor. It must be fuel injected because you you could hear the pump running in tank fuel injected cars have there fuel puns in the Gas Tank
