1997 BMW 328 No crank, no start, no push start

Hi. My 328is will not start. I put a fully charged jump box on it to be sure it had enough power. The key turns all the way, the intrument cluster lights up, but the starter does not bugde. I thought I had a bad starter and then had a friend pull the car with his truck so I could get a start off of the clutch. I eased off the clutch and the engine came up to rpms (about 1500-2000) but no rpm reading on the cluster and the engine would not kick over on its own. Tried this three times and got nothing. I even jumped the starter with the key in the on position. I checked both sides of all of the fuses(all have power), swapped all of the relays(with the proper ones), and checked for power at the DME relay and to the DME afterwards. I recieved power to 8 pins with the key on, one with it off. My friend has an M3 with the exact same DME but if I try it I dont think it will work with my key because key has to be coded to the DME. Any advise?
