If I understand you correctly, you are saying that the fuel pump runs with the fuse removed. This should not be possible, but maybe I have misunderstood and the car is only running for a few seconds with the fuse removed.
If that is the case then the fuel pump is just running for a few seconds to build up fuel pressure as it is designed to do when the ignition key is turned to the first position.
I think that you may have a problem with the "Speed switch relay" which is located in the cluster of relays that are mounted beside the battery. The speed switch controls the fuel cut-off function when the car does not need fuel (e.g. deceleration). Check the contacts of the relays, I think the speed switch is blue and has part no. 0.280.230.006.
If the car runs for more than a few seconds without the fuel pump fuse then someone has butchered your wiring loom!!!Holger wrote:
