Hello, since yesterday he has the following problem : After a long service life (over night) he starts normal. After approx. 3min stand gas he goes out and then starts only very badly. One has to “pump” with the accelerator pedal. At some point he arrives then. However, then the MKL burns. Also all further attempts to start go only with extreme “glow” and “gas pedal pumps”. It also happens that one does not get him to run (have today the battery empty-gelled) fuel pu mpenrelais has already been changed without improvement. I suspect the petrol pump (in the tank). Can it be that the car is also running if the pump is not working in the tank? The electric connection of the pump is subject to voltage. Do you feel if the pump is working (vibrations)? Could it also be the Lambda probe? What could cause it to work after a longer service life for a short time? Is there another reason for it? Thank you for your help.
