    Thank you for your help. It is greatly appreciated. It actually turned out to be the battery. Someone had changed out the proper battery with one that was not strong enough for the car. The other battery would not even work with a charge from an industrial unit & had to be towed on a flat bed. Thank Goodness! The expense is a real shocker with this car! But it is wonderful..

An s600 is basically two engines bolted together. The fact that it doesn't even try to run on at least six cylinders tells me that it is most likely a control module problem or an EZL-this is located on driver's side under hood on top of wheelwell(you'll need to remove the cover panel to access). It is bolted on and probably even has a vacuum line going to it, along with three plugs. This is not cheap by any means, so look for a used one online. This is about the only unit that you can replace without having to take it to a shop, and unfortunately it oftentimes will scrap a vehicle(due to the cost)

1994 Mercedes S600 right side engine has raw gas smell. Not the oxygen sensor.

I would check the fuel pressure regulator first,pull the vacuum hose off and see if there is fuel in the line,if so the diaphram has ruptured and raw fuel is being sucked into the intake

What does it mean when 1994 mercedes s600 engine ticking?

The most common cause for ticking is valve train wear. Though engine failure is not imminent, it is an indication that the engine will have to be repaired. On your vehicle it will be a potentially expensive repair. Some engines last thousands of miles with such ticking but it's a gamble to neglect the repair.
