WTF?
I'm tracking the residual pressure leak to solve long cranking. I changed FPR to new, changed rubber fuel lines, no gas smell below the car, replaced BMW check valve fix AGAIN. Replaced injectors to Five-O Denso ones.
Still loosing pressure.
So I took out the fuel rail and charged it with fuel relay activation trying to find injector leaking from the nozlle, found two. I found two from my original ones that were NOT leaking. Charged again and waited overnight.
Now, get this, NO leaking with fuel rail/injectors out of the manifold.
I put it back together and resid. pressure leaks out in 2/3 hours.
My question: is there some kind of electrical triger making injectors open up?
What else am I missing. There's nothing else left to change!
