So I know this topic has been beaten down, but t so many threads have also ended without actually reporting a fix.
My BEW has recently (last fall) started having trouble starting and staying running at first start, it is only a summer vehicle so winter operations are of no worry.
I’ve done all the normal checks, repairs, and testing and I’m still short an answer as to why this is happening.
Car has a new low pressure fuel pump, new tandem, new rubber fuel lines, new 100% injectors from Darkside, new injector harness, fresh fuel filter, new OE crank sensor, crank sensor is grounded through the ECU as per the write up, timing is spot on, torsion value is 1.1, and the list continues on.
After the first try to start it requires prolonged cranking, as if there was air in the system, after it’s started it runs 100%, no issues aside from when I let off and come to a stop the idle dips ~100rpm and jumps back to normal. There is absolutely no issue up top or on pulls, power is good, smoke is a haze.
I’ve been pulling my hair out trying to fix this, and I’ve seen answers as crazy as a crack in the fuel channel in the head that bleeds to the crankcase..
Any input is always appreciated.
Thanks
