[s-cars] Strange issue - Fuel Pump?

[James Shackelford]

Hi all,

 

My 95.5 S6 Avant has been exhibiting some strange behavior lately, I am
wondering if it might be the fuel pump getting close to it's last..

 

Right after starting up, and only if it's been sitting for 10-15 minutes
(cold, after shopping, etc, but not after just jumping out for a minute)
there is a span of maybe 20-30 seconds with no power.. The engine won't even
rev past 3000-3500 (with no power either, no boost or anything), then after
that 20-30 seconds it's fine.  Thoughts?  I was thinking maybe the fuel
pressure is taking a while to build or something.  After this period, it's
fine.  I think I remember someone having the same problem recently.  FYI, if
I start it and let it run for a couple of minute before taking off, the
problem doesn't appear...

 

Fuel Pump?

 

No engine mods except 1.8T coils

 

Thanks for your help.
