Reading through the posts, I think i have a similar problem with my '95 E320 Sedan. A week ago the car wouldn't start only 15 minutes after shutting it off, the battery was fine, and it did have a buzzing sound. I replaced the starter and discovered it wasn't the starter, but the relay that fits in the fuse box under the hood's hinge on the driver's side. After changing, it started instantly. the next day the car wouldn't start. All the electrical wires are new. Any advice on what to do next would be greatly appreciated.

Car would not START or would not CRANK ????

The car would not crank.

OK

Take out fuse #5 and clean the holder ends and replace the fuse.
Or, next time the condition exist, spin the fuse in it's holder and retry...
also, try N on gearshift gate.

Okay I will check into replacing all the fuses, but one thing I notice and that is my Fuse "C" red 16 Amp is blown. I replace the fuse C and watched it burn out before my eyes. There must be a short somewhere. Any place I should star?

I have all the strange behavior that redheadeight had with his E420
