once again, thanks for the help. your info has been invaluable to me.
and i m sorry if it seems like i didn't take your info into consideration... i definitely did and all indications are still that the pump is the problem.
But the thing that is puzzling me is that my fuel feedback pressure and voltage are staying at exactly 380kpa and 0.6V , no matter what the car does.
I see that the Fuel Pressure demand value changes according to throttle position... from 5000kpa upwards as i press on the throttle, but the feedback values remain exactly the same all the time without changing at all.
So (regardless of the issues with the regulator and pump) , I am just wondering if this is a sign that i will need to get a fuel pressure sensor since it seems odd to me that the value will not change as I change the throttle position.
