I think that the best way to diagnose fuel delivery is to observe the pressure at WOT. Attach a fuel pressure gauge to the windshield and recruit a co-pilot. Run the car at WOT from 3000 to 7000 rpm. The fuel pressure should snap from 43 to 51 psi +/- 1 psi.

It can draw attention tho. I stopped next to a bar to re-tape the gauge to the windshield. Musta been 10 dudes surrounded me to say "WTF", soon as I opened the hood, followed by the (usual) "I never knew..."
But, while we're on the subject, Marc, where is that handy place to measure total FP current draw?
