Hi I'm looking for some advice on this one. fault logged P0071 fuel rail pressure low. What happening the car runs but as soon you rev him up it goes to limp mode.Car comes in with 4 injectors fitted.This is dual control system imv and drv.My question is :on the fuel rail there is connector which for me looks like dump valvemaybe called safety valve . Could someone correct me? Because when I connected leak bottles to it it has got constant fuel leak and this could be the problem. One more thing drv drive for 21 % on idle a little bit too much I think.
I don't know how to attach the pictures , here is the link to ebay with the same rail . And it is the gold connector.
