You can't " give it gas" ; there is no squirter like on a carb to spray fuel in.
Putting your foot on the pedal , cuts OFF the injectors because the computer think you are trying to clear a flooded engine

If it starts with your foot on the pedal, then you have TOO much fuel in the engine. Start looking at leaking injectors , leaking cold start injector etc flooding the engine with fuel.
Obviously with too much fuel , you have to keep the throttle open when it starts because it is too rich. Like a carby car with the choke on.

Do the injector leak down test to see if injectors are leaking. Disconnect the supply line to the CSI and see if it still starts rich
