david,
simple answer lang yan. the fuel pump needs to pressurize the lines kasi overnight nawawalan ng pressure.

wanna test this theory? ganito.. after you've started out for the day, you say 1-click start nalang, right? OPEN YOUR GAS TANK. sisingaw yung pressure buildup. close the tank again. i bet hindi na siya 1-click, you'll have to do the 3-second delay bit again. but in my experience, hindi dapat kailangan i-bomba yung gas pedal: the engine computer will automagically give a super-rich mixture (equivalent sa pagbobomba) when cranking. maybe your IAC valve (ISC or servo..) and/or throttle body needs cleaning. gummed-up IAC means trouble when the ECU wants it wide-open (e.g. when cranking) and some rough idling.

normally EFI cars run rich naman eh, so a gasoline smell isn't abnormal. i've smelled gasoline around my car's back end for a couple years now. wala namang sumabog, and my fuel mileage is just about right for a car of this age and displacement.
