    Cleaning the TB is probably not bad, but I have my doubts it's the root cause of your problem. I agree, if you are going to clean the TB right (as you should), take it off, other wise you're not going to get it all.

    Once the car is started, how does it run? Is it misfiring? By the fact it runs once started, we know you have air/fuel/spark. Pressing the gas is probably coincidence (since fuel injection should adress that). One guess I could make is a fuel line leak. When the car is off, the fuel leaks out the line, thus creating a problem starting (as you need to wait for fuel to work to the front and pressure build up). Just a guess, we need more info.

    My bet is a vacuum leak.

    Seriously.. I'm thinking your issue is either fuel pump resistor or maf sensor.

    I'm not an English major, but really? I couldn't take it.

My car won’t start and I have spark need to press the gas to be able to turn on. I can hear the fuel pump when I turn the key to on position. I haven’t check fuel pressure; I’m going to.

    Better? Its amazing what Word spelling and grammar check can do.

    But yea, I would guess fuel pump may be getting weak or a bad resistor. But more information would help.

    grammar and spell check:

    He's being a dick about your spelling.

    If you're referring to the vacuum line, its pretty different from an electrical connector as it has to create an airtight seal.

    In other news, this thread is from last year.

    Quite a long time to live with an issue like that.
