Hmmm, looks like your Capslock is malfunctioning as well.....what exactly do you mean by "when I try to started, the whole thing turns off like it had a kill switch". It won't crank? All vehicle electrical shuts off in the crank position? Is the fuel pump running? You need to be a bit more specific. Could be anything from a poor battery connection to a non-functioning fuel pump.
