[s-cars] (no subject)

[Tom Green]

Ok Brooke, I'll stop trying to be cute, and proofread as well.

Like it or not, DIY is the only practical solution to URS-6  
ownership.  The
dealer network has almost no 5-cyl expertise left, and yes that is  
important.
Even if you have one of the few shops near you that does have this  
special
knowledge, you have to know enough the manage the required service and
tell the shop what you need.  That's why we are all here.

I would have to be 100% convinced it is not a fuel problem before  
moving on.
Starting with the FPR, vacuum lines that control it and other things,  
and the fuel
filter is ok since they need looking at or replacing anyway, but I  
believe you will
be in the tank after the pump eventually.  I don't subscribe to the  
finite life theory
of 100K but if you are having these problems and can't find the cure,  
perhaps it
is time.

If you feel the pump is working ok it could well be the FPR dumping  
pressure
right back to the tank or the filter blocking it there.  Those things  
have happened.
ECStuning.com is selling them cheap.

In all your list of previous work done, there is no mention of any  
DTC's.  Have
you checked for trouble codes?  I don't expect much help here but  
even the
absence is some help.
