No, but not far from LI in Queens. I'm back on the road now thanks. My problems started after I did a few 0-60 timed runs. See this thread for more info:

Engine won't crank

I suppose the extra stress from the timed runs loosened an already loose ground strap bolt on the bell housing to cause a no start and the weird electrical problems I was experiencing.

Since I tightened the loose ground strap, the car now starts fine. However, there's a new problem: The coolant temp and fuel gauge are now both pegged at the upper end of the scale when I am on the hwy. When I'm stopped at a light, most of the time the 2 gauges are pegged but sometimes it jumps between pegged and normal reading.

Hey Tom, where exactly is the problem this time?

You don't know what I went through to fix the coolant temp and fuel gauge! I checked everything. The temp sensor is ok, the cluster has a good ground, the gauges are getting +12. The gauges work except it's indicating 80 deg and 1/2 tank too high. Turned out it was the gauge pod! I reseated the circular connector a few times which didn't help. I took it out, re-soldered every connection, found an almost melted copper trace and jumped it with a piece of wire, put it back and the gauges now read normal. What a PITA that was. What bothers me is the unlikelyhood of so many seemingly unrelated problems poping up within a few days. Hope this don't happen too often.

My guess is that they may not be unrelated. If the engine ground strap was loose, the only other path to ground could have been through the instrument cluster thus burning out that wire.

That has crossed my mind. If a loose ground strap could burn out copper traces in the instrument cluster, I would call that poor design on the part of Mercedes engineers. If I am really curious, I could pull the cluster, buzz out the burned trace, draw a diagram and analyze if that is possible. Maybe next time I'm in there.
