Re: Hard to start after sitting a long time?
Try this:
Turn the key to on only & wait for the fuel pump to cycle off. You should be able to hear this in a quiet area! Key off. Go thru this cyle 2 or mabey 3 times to build up fuel if you have a lazy pump or inards.
If this works on a every time bases that you have to use it after the car sits overnight you know there's either bleed down of pressure or a weak pump on initial start up. Getting your pressure chk'd with a gauge will either eliminate or confirm a weak pump & point you in the direction of a weak fuel pressure regulator.
