Hi! I have a very specific issue in m20b20 520i. DME doesnt give ground to activate the fuel pump relay. If I jump the relay or just jump ground from the constant ground pin to dme ground pin the car works like a charm. The fuelpump relay activation ground wire comes straight from the dme. Is there something im missing or is the DME bad? Since everything works with just jumped fuelpump relay I assume all the sensors and main ground distribution should be fine?
