It could be a host of problems that will cause this. It could be a fuel pump, fuel pump control module, fuel pump relay, you could have a dirty throttle body.


If you have to pump the pedal like a madman to get it started then I would bet it's the fuel pump. Checking the fuel pressure will help confirm the diagnosis.


As the above stated, check fuel pressure first. For a long time now starting cars do not require the gasoline pedal to be depressed at all for starting. In fact, the proper procedure is not to.
