Default Fuel pump problems?

Well...I have an 03Z and lately it has been starting kind of funky in the
morning...it takes a few cranks to start and then starts a little roughly
on initial start. Restarts later in the day are fine and it starts instantly.
Yesterday I drove a lot about 150 miles of mostly highway and late in the day I heard a whining sound coming from behind...thought it was some radio interference, but it was still there when I turned the radio
off. This morning...hesitating start again...but no whine at all. I am wondering if there is a problem with the pump when it gets hot...causing whining...also seems to be a loss of fuel pressure when
sitting over night...hence the delayed starting.

Mine seems to be one of the 03's with the new fuel system...so I imagine its a nightmare to change out the pump. BTW the car has
28000 miles.



Any input or experience would be appreciated.

Andy

Do you KNOW that you are losing fuel pressure or are you guessing that because the car is slow to start? Any codes present?

There are no codes at present and I don't hear the fuel filter unless I
drive a lot..then it gets noisier. It definitely does not start instantly
like it used to. There is no way to change the fuel filter in this new
fuel system...it is in the tank.
