IS IT A F.I. B2200 OR CARB'D? WELL, SOME CARB'D MAZDAS HAD AN ELECTRIC FUEL PUMP IN THE TANK AS WELL AS THE F.I. MODELS. IF IT WASN'T THEN IT WON'T HAVE A FUEL RELAY. WHAT SEEMS TO BE THE PROB?
My neighbor changed the fuel pump that was in the gas tank. The truck started up fine. A few days later he went back to move the truck and it wouldn't start. Someone said to change the fuel relay.
