Question about Mercedes-Benz C-Class
I am assuming that the engine won't even turn over. could be lots of different things. The simplist is to make sure the car in in PARK , won't start if not. Other things could be , Security imobilizer if you have one. Does your key have a electronic chip in it ? Try your other set of keys if you have one. Check if battery connections are clean and tight.

EPC refers to the drive by wire system. This system, generally speaking, encompasses the throttle pedal and its position sensors (it needs to know where your gassin' foot is) and the throttle body.
Most likely, the EPC light and its associated faults for this scenario are a symptom, not the problem. Meaning the actual root cause is causing the no-start/no crank issue AND fault codes related to the EPC system.
And the most likely root cause is an ignition switch, NOT the engine speed sensor.
With a bad engine speed sensor, the car will still crank all damn day (or until the battery dies) but the car won't start.
If you get a no-crank issue, and then it eventually starts either with or without an EPC light, again, the most likely problem is the ignition switch. Not the starter, not the battery (though the battery proper and the cable connections must be perfection itself to rule them out.) You can get these issues with a visually perfect but still faulty battery connection.
