Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

if you really have a carburetor as you say, you have a mechanical fuel pump so you will not have a fuel pump relay. if you have fuel injection then you do have a fuel pump relay, need to know which engine it is to help more.

FUEL PRESSURE MUST BE 62 LBS. OR GREATER OR IT WILL NOT GROUND INJECTORS, IF ITS OK THEN CHECK YOUR GRAY 12V SUPPLY TO PUMP AT CRANK-UP, YOU MAY HAVE A POOR IGNITION SWITCH.
