Electrical problem
1987 BMW 535i 6 cyl Two Wheel Drive Automatic 230k miles

We used the car yesterday with no problems. Tried to start it this morning, there was a loud bang, puff of smoke out the driver side and smell of electrical burn.

Engine will turn over, but will not start.

Do you
have the same problem?

Wow, sounds like a explosive event. Have you looked under the hood? If so, what did you find?

Head gasket: no water in oil or visible on exterior. Timing belt: need to check, but would not explain electrical smell.

No fuses out, all other electrical systems work.

Unless it is the timing belt, I would think it would have to be a short in the ignition system.

I will also check the fuel pump.

Any other suggestions?

Your problem is not a timing belt because there isn't one, check for fuel pressure and spark and compression.
