I just bought a 87 740 gle and i drove it about 80 miles and it died about
30 feet from my house, the car had troubles running as i drove it and it died but fired back up without me returning the key to start it (this happened while driving down the highway at about 70mph) after that happened a few times it ran great untill it died. the cars insides lights on the dash near odometer do not turn on when i turn the key nor does the car attempt to turn over, no clicks no nothing, i have replaced the battery and spark plugs any ideas on how to get my beast running? Thanks Christian
