Long time Benz owner and never had this issue. 2001 E320 decided not to start, thought it was fuel pump so we tried a little starter fluid and it fired. Check relay and was fine. Disconnected battery to reset computer and it fired up. Drove it a few times and no issues until last night and it repeated issue. Repeated disconnect battery and it fired up and ran. Checked for errors and nothing. Any ideas on how to proceed or where else to look? Tim
