5000cs cold/start problem
1987 5000cs quattro sedan, no mods, as is factory. Have hesitation or miss while under load, especially during climbing hill in 4th or 5th. When ever I unplug (electrical-blue) conn to cold start injector everything is a-ok, no hesitation .
All other functions ok, no surging at idle.
update, went for test drive cold start unplugged all was well then after about 20 min of driving car died. Instrument display showed picture of gas pump. re plugged in cold start no difference no start, display shows picture of gas pump. ran output test along road side ,fuel pump is running but at what pressure I have not checked. what is a good pressure and where best to check it? Could this be coincidental that fuel pump has gone weak?
