Will not Start on 2003 Mercedes-Benz C230

last week my car stop working. 1st - it crank but did not start. So I checked the Fuel Pump, Battery, Ignition Coils is good. I ended up replacing the Cam & Crank Shaft Sensor and still the same results...NO START. I Then replace the MAF sensor and still no start. Yesturday, I tried to start it again thinking maybe it was flooded the day before..and same result. Today I tried starting it again, now the car wont Crank & Start,cant hear the Fuel pump going, no clicking on Starter..but Battery is good...All Windows,Stereo,lights are on. I did notice burning smell right by the (MAF & Wiring Connections,Ignition) areas. I Need help!!!

The computers on cars are sensitive burned or shorted out wires could damage the computer. Just replacing parts is never cost effective but it sounds like you have a good idea about cars. Do you have a manual so you can follow test procedures? Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is also a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
A professional grade scan tool is great to read live sensor data to see key sensor values without having to do intrusive testing at each sensor. You will like Alldata its what we use at work.
