The fuel pump is located in the fuel tank. The fuel tank will need to be removed from the vehicle to service the fuel pump.

There is no reset button for the fuel pump on a 1985 Seville. You most likely need to replace the fuel pump.

99.9 % of all fuel pumps in vehicles, made in the last 30 years, are in the fuel tank

It has to come out of the car,to remove the pump, from the top

TO replace the fuel pump, remove the gas tank. When replacing the fuel pump also replace the strainer on the bottom of the pump and replace the fuel filter.

The fuel pump is in the gas tank. Disconnect all hoses and electrical wires from gas tank. lower gas tank. Remove ring that secures the fuel pump assembly and pull assembly out, be careful not to damage fuel float assembly. When replacing fuel pump, replace the sock and the fuel filter.

It should be either no Spark or no Fuel.
Possible causes: Out of gas, no oil pressure, faulty oil pressure switch, Bad fuel-pump, fuel-pump relay, needs tune-up, defective ignition control module, wrong air/fuel ratio, defective IAC valve or EGR valve.
Other causes: Wrong timing, bad compression, or clogged CAT.

the fuel pump is located inside the gas tank in a module called the fuel pump/sending unit module, the tank must be repmoved to replace the pump.

Check for a burned fusible link under the hood. If you have power at the fuel pump relay, you could have a bad ignition switch or bad oil pressure switch...accordianman
