My z3 coupe 2.8 had no crank and no start. I tried to jump it but it’s definitely not the battery because all lights come on including headlights. I tried a push to start and that didn’t work either. That kind of ruled out the starter but I bought a new one just in case. Before installing it I figure I’d consider other options. I made a jumper wire for the power cables on the EWS and the car cranks but does not start so the starter is definitely good. Does this mean the EWS is shot or was this just a test for the starter? What else should I check next? Some other symptoms include the cluster comes on but none of the gauges move and an obd scanner can’t make a connection to the car. I’ll keep you updated with any other symptoms I find. Any ideas as to what can be causing this?
