anyway, that's definetley high. i've got the Focus pump and it runs about 22psi at idle and 40psi at WOT. sounds like there might be some sort of electrical problem somewhere. maybe a sensor.

My '04 is 40 with ignition on, 32 while running, 40 at WOT, then after it's real warmed up and about 105+ temp outside, fuel pressure runs at 40 regardless of throttle position.
Then once in a blue moon it'll shoot up to 55 or so, then go down to 20, then go back to 32ish. No clue.. stupid.
