Hello, wanted to report about a problem with my Lupo 3L. After approx. 1500 m drive the engine starts during the ride. Several start attempts futile. Engine turns on but no signs. Tow off and off to the workshop. For information: The Lupo 3l has no fuel pump in the tank but at the front of the engine a tandem pump (vacuum pump and diesel pump in one) In the workshop the return run from the pump to the tank has been clamped and see, the engine is running. So the error lies somewhere between the pump’s front and back run. First the suspicion was that the injectors are leaking. The seals were somewhat rubbed but probably not the cause. Nevertheless, the seals were switched. (approx. 30 Euro per injector) Next the pump was removed. With the help of a hose and funnel diesel was connected to the feed and turned by hand the pump. The diesel came to the largest part from the return run instead of the pressure side to the injectors. Unfortunately I still wait for the new pump. Did someone already have such a case?
