I have a 2006 bmw 330i n52b30 3 stage intake. I am cleaning my fuel injectors and replacing the o rings but Everytime I open my door if the battery is connected my fuel pump kicks on for a second and spits fuel. Is that normal?

I think this may explain my code on the power management also the 2ded or something close to that.

thank you. I didn't think it was but now I know. had a misfire in cylinder 6. changed the plugs for cylinder 4,5,6 and put new coils on 4 and 6. cleaned the injectors and swapped them from 6 to 1 5 to 2 and so forth. still have a slight missfire. I know I had to do my valve cover gasket because it was time. but noticed a snapped bolt just sitting there close to cylnder 6 on the fuel rail side. would this also cause a misfire? I cleared codes also swapped vanos and cleaned them as-well as cleaned my maf.

don't know if I should just buy all new coils and plugs and replace all or what this time. I haven't ran the code again to see what cylinder is missfiring but I want to run about 100 miles. the missfire only happens at idle after about 30 seconds and in between 2500 to 3200 rpm any gear. could this be a disa issue?
