    X1 other than that, super dirty injectors cause hard starting.

    Fuel pump is great.
    once it starts black smoke comes out.
    From pumpng the gas.
    And one day I need to take ot those injectors.

    Leaky injectors. Fuel needs to be finely atomized to burn cleanly. Leaky pintle valves in the tips will actually drip and allow fuel to puddle on the piston tops.

    And is that why it is hard to start sometimes.
    It only happens here and there.
    But How do you fix leaky injectors?
