First question: Did it run before you added the injector cleaner or did you add it because it would not start? If it was not running right before you added the cleaner, the cleaner is not your problem. It is highly unlikely that a standard off-the-shelf injector cleaner would cause any damage. It is possible for it to move some dirt in the system and POSSIBLY clog one injector, but highly improbable that it would take the entire system down. If anything, you have stirred up something in the tank and clogged a fuel filter and/or strainer on the pump.

I would first change the main fuel filter - it is located under the car and is rather easy to change. If it is the strainer, the pump has to be removed.

More common on Mercedes V8s of that year is either a crank/cam sensor or an immobilizer issue (ECU not recognizing key). Either way, it would be a good idea to have the codes ran on the car, not just the OBD codes, but get a shop that can scan the actual Mercedes codes.

Best of luck!

2005 Mercedes Benz CL65 AMG goes into limp mode when accelerating onto parkway or when trying to pass another car. Starts running rough with loss of power.

Fuel injector may be dirty. Put a container of fuel injector cleaner in gas tank (10 gallons) and run for awhile. May improve, I've had that problem and cleaning the injectors worked. Available for a few $$ at most auto supply stores. Worst case if that does not work may be to suspect the fuel pump and/or vacuum hoses.

What is the cause of a misfire on cylinder #3 on a 2001 mercedes benz s430?

Generally speaking it can be a spark, fuel, or compression-vac leak problem.
So the spark plug, coil, fuel injector, vac leak, or internal engine problem would do it.

You most likely have another fuse box either in the glove box or under the dasy. It sounds like a blown fuse.

Locked out my 2000 S430

there is a mechanical key that slides out of your smart key. I beleive the release tab is at the base of the smart key. You can then put the mechanical key in the tumbler and unlock your vehicle.
