Fuel pressure numbers?
Anyone know fuel pressure at idle and at throttle on 2006 E55? Having start up issue son my 2006. Car is holding 84psi in rail and won't crank right up. After a few days in garage pressure bleeds off and cranks on first try. Didn't happen till after fuel tank recall?????

80 psi +/- 3 psi is in the ballpark.
Pressure will bleed off within 24 hours to single digits.
My experience with my car with fuel pressure gauge connected 24/7 for several weeks while troubleshooting.
YMMV.

Yep ...75-80psi. Just to show you that the factorey filter is and becomes a bigger restriction on the pump....when I pulled mine out and iliminated it then whent to an inline filter, pressure jumped right up to 78psi from 65 psi. Big difference.
