failing fuel pump usually. check fuel pressure.
The fuel pump is in the fuel tank but there is also another fuel pump on the drivers side frame rail. its a high pressure pump for the fuel injectd models. located just forward of the fuel filter.
Ensure that the fuel Pump is PRIMED and also that the electical connections are good to it. If all is good there, check for a kink/leak across the lines.
To check if the fuel pump is working on a 1993 Mazda MX-3, first ensure you have a good battery charge. Then, listen for a humming sound from the fuel tank when the ignition is turned on (without starting the engine), indicating the pump is priming. Alternatively, you can check the fuel pressure at the fuel rail with a pressure gauge; it should meet the manufacturer's specifications. If there's no sound or insufficient pressure, the fuel pump may need replacement.
There are two. one is in the fuel tank with the fuel pump, the second is at the fuel pressure regulator
Low fuel pressure (fuel pump, pressure regulator, fuel filter), vacuum leak, partially blocked/fouled injectors.
Hook a fuel pressure gauge up to the shrader valve on the fuel rail.
