Recentlly purchased a 82 320i 3 months ago and have had no problems until now. I cleaned my battery terminals with bakeing soda and water and failed to notice that the solution had dripped on to my alternator ground wire and eventually ate through it. When I figured out what I had done I had to do a quick fix and tape/ mount it back on to the starter and it started right up. Thinking that I could wait until the weekend to do it right. Wrong! As I was driving down the freeway my RPM gauge and oil temp gauge started jumping like crazy and then a small pop was heard and the car died. I checked the ground wire again but to no avail. The car turns over but never runs. Yes there is gas in the car. But I am not sure if by having the ground wire bounceing off and on the alternator would have smoked my ignition coil. Any thoughts and suggestions are welcomed.

Thanks to all, Eddie

Testing the coil is a done with an ohm meter.
Pin #1- to pin #15+ is 50 ohms.
Pin #15+ to the center tower is 6000 ohms.

I would be suspect of the fuel relay.

Here is an e21 ignition diagram.



Here is the fuel system.
