Hi Everyone,
Chasing a lean code...grrr
All new vacuum lines and I fogged it...no help
2003 R53
Fuel pressure at the end of the rail with key on is 0.
At idle 39-40....10+ psi lower than a mini S should have.
High revs...no change
Replaced filter 2 weeks ago...no help.
Also, fuel vent valve clicks pretty loud..got one on order.
Do fuel pumps get weak before they go???
or is there another problem at hand.
Thanks, Mark

 

Moving you to the Stock Problems/Issues area.

Could be the fuel pump, don't know if there is way to measure the amp draw.
