What will make my Mercedes C230 Kompressor sport stop running act like it wants to start but won't

Hello, is the engine cranking fine and not starting? If so, there is a loss of fuel delivery, ignition spark, air to the intake manifold, emissions controls issue or engine compression / timing issues. Diagnostic testing is the only thing that can determine what is happening. I'd love to help you, but you'll simply need to seek local assistance at a shop near you. They can definitely help you.
