This is a friend's car, '87 560 SEL, stalled and won't restart - happened Friday about two blocks from his house on his morning commute. I'm going over to look at it today.

Dave reports that occasionally on a cold start it will just barely idle (500 or less revs) and runs very rough, but then cleans up. Friday he got about two blocks from his house, and then it stalled and would crank but not start.

There seems to be a number of KE -equipped cars that show these symptoms. I'm going over to Dave's this afternoon and plan to check for spark. If okay, then it's probably fuel system related, and I'm going to look at the OVP relay and fuel pump relay.

Any other suggested troubleshooting?

I believe 560s have two fuel pumps. If one fails, will the other allow the car to operate at low load?
