My 1990 200Q would start ok when hot or cold but hard to start after sitting 1-2 hours lots of cranking to get it going. Now won't start at all first lost the fuel now no spark. Less than 5000 miles on a new Pierburg pump. Replacing fuel pump didn't help. Some have suggested crank sensor. When trying to start tack does not move at all. Not sure what to try next. Have minimal electrical experience and not much advanced testing equipt.
