Check the fuel pressure if it's within specs to rule out the fuel pump/fuel filter.

Thanks for this reply. How do I know that the pressure of the fuel is not enough. If I put my ignition on, the fuel will not come out except I try to start it and it will flow gradually. Could it be bad

Use a fuel pressure tester
