Check your fuel pump relay .

It is possibly a fuel pressure issue, if the terminal pressure at the injectors is not sufficient the injectors will fail to open, you will need to check the fuel system pressure, before and after the fuel distributor.. Possible failure lies within the fuel pressure regulator.
