2013 Mercedes C250 cranks but won't start after overheating

What is your question?

My car overheated, there's no signs of a leak anywhere, no water in the oil, I added coolant since it had none, I sprayed starting fluid in the air filter, and I tried jump staring the car. It cranks but it won't completely start. If anyone can help me pls I really need my car to run.

How long has your 2013 Mercedes-Benz C250 had this problem?

A few weeks since it hasn’t been running
