My '89 740GL wagon (NA) crapped out on me for the first time today (oh the humiliation of towing) after 207k trouble free miles. It worked fine in the morning, then I went to start it in the evening, it started up for about 2-3 seconds and died, and it hasn't started since. It turns over fine, but no spark, no fuel because as soon as I get the key to the on position (not even turning the starter)fuse #1 fries. I've checked the basic ignition connections, cleaned and tightened all the fuse connectors. I'll get to the grounds in the morning, but before I start tearing into her I thought I'd check to see if any of you have experienced the same problem. I've already done an extensive search on the site. Seems like a tough one to diagnose considering as soon as I power her up, the fuse for the fuel, and the control unit is already blown. Any ideas? Anybody?
