That sure would be the best outcome John. I do have one in the other 300E I just bought - oddly - working well in that car - it has *two* fuses in it - a ten amp and a 15 amp fuse side by side.
I'd sure hate to fry this other one too - is it a case of that OVP "giving up" or could something else fry one of these units?

From my experience, your car should start and run without the OVP relay. It takes longer to start, but it will start and run. You just won't have power to the Idle Control Valve, ABS Computer, and the Fuel Computer.
But, that doesn't mean you shouldn't have a good OVP Relay. I wouldn't mess with a used one....get yourself a new one.

However, it will not run without a good Crankshaft Position Sensor (CPS). If it is going bad, you might have intermittent starting problems or hard to re-start after parking it for 30 minutes or so. If it's dead, then no spark, no start.
Do a search for Crankshaft Position Sensor problems.
Yes , I know it's late on a Saturday night, but I just returned from China and my sleeping pattern is out of whack.
