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.
