I'm not sure how that could be any more irrelevant.

If the crank sensor was bad wouldn't the fuel pump not kick on? I had an e36 with a bad crank sensor that was diagnosed by another shop as a fuel pump. I then determined the pump was not coming on and I had no spark and checked the crank sensor.

Maybe its different on the e30, but It wouldn't make sense to me.

From my experience engine cutting out is due to either sensors, ignition. Or fuel pump\ sending unit if not then electrical?. Goodluck.

well, knock on wood but the problem hasn't returned.

I think it was a combination fuel pump relay and, more likely, the actual connector on the fuel pump itself.

I noticed the connector on the fuel pump made solid contact, but it came off pretty easy. When I cranked the car, I didn't always hear the fuel pump running. Then whenever I put the access panel back on, the connector would back off and car would not start.

My solution was to ziptie the connector to the output fuel line therfore holding it nice and tight, as well as cleaning the contacts. I also replaced the fuel pump relay (had a new one lying around) and will still be picking up a main relay as extra insurance
