    I need to change the Fuel Injectors, engine misfire already replaced the coils. But the Misfire is so bad on on the engine that I'm worried it's going to tear up my new catalytic convertor, and destroy my engine.
    So I can easily disconnect the fuel pump, and even open the gas cap but I can't start the car for fear of further damage. So does anyone know of an alternative method to not have gas spraying all over the place?

    Just touch a 9 V battery across the terminals of one of the injectors and wait for the hissing to stop, which won't take long with the fuel pump not running.

    That will have sprayed the fuel into the intake port, but the rest of the job will take you long enough it will have evaporated and shouldn't make the engine hard to start.
