I have an 03 5.3 liter V8 Burb and I am having a lot of the same issues decribed in this thread.
A couple of other things happening to me are while driving down the road my engine basically cuts out - hesitates really bad, I can feel the power steering go away. I have no smell of gas or leaks that I can visablly see.
I have replaced the Fuel Filter and the plugs to date.
Any advice on the Regulator as for its location and what it looks like? From what I read if I find this and pull the hose there should be NO fuel in coming from the hose - correct? If wet at all then bladder is borke and it should be replaced.
Has any done a Fuel Pump on the Burb in order to give some direction?
Thanks,
Stitch
