I have a 1990 325i and it wont start it just died driving down the road one day and hasnt started since I have spark and fuel and the timming belt is new and the valve train is rotating but I have no compression in 5 cylinders the compression in cylinders 1 through 5 is between 12 and 65 psi but cylinder 6 has 171psi any ideas as to why I have low compression in 5 cylinders but good compression in 1 cylinder if the timming was off would there be compression in only 1 cylinder? I have not checked the timming I will be doing that in a day or so.
