I've noticed a change in the way my 99 V6 starts when I first start it after sitting overnight. It will usually stall out after a lengthy crank (5-8 Sec). In the past it would usually start up much faster without the stalling.

Can anyone share their insights on this? I felt it was mostly do to the warming weather. I'm not overly concerned since it's been running well since I reinstalled the Turbo earlier last month.

Could this be down to the US and the winter / summer fuel change over I often read about?

Summer gas formulation and cool morning temps will cause this problem.
Same thing happens in the fall.

Thanks guys; I was looking for some consensus on this before I considered monkeying with the TB.

How about the check valve on the top of the fuel pump?

I honestly think your fuel pump might be weak. The "summer gas" thing has never effected any of my cars. So if was me I would change it out before it stops working.

I replaced the fuel pump last summer; I sure hope I don't have to do it every year.

Nope should be good for many years!
