here we go...ive been having problems starting my 1986 325es...ive asked for help in another site and i was only directed toward ground cables, which i checked for and found nothing to help the situation...but neways ive been having problems starting my car..SOMETIMES...but i do not see any explanation since its pretty much 50% starting and 50% not starting...this includes cold starts...the engine cranks when it does not start but ive noticed that the rpm needle does not jump AT ALL when its not going to start...another thing is, the car seems to have trouble starting the most when the front of my car faces up toward a slope..i thought this might lead me toward having a fuel issue but im not sure....if any of this makes sense and if anyone can help ,plz direct me toward my problem...thanks guys.
