newbie w/ 300ce no spark issue please help!
 

I have a 1990 300ce, 104 engine. while kicking down the pedal to climb uphill, I lost all power, and had to be towed. Further inspection revealed no spark. Coil is good, and so is power to it. I don;t know what to do next. .

I only have the car a week and it was such fun to drive. Now it sits with the hood partly open. I have read alot about wiring harness problems and wonder if that is my issue or if I need to be investigating control units and sensors. any info would sincerely be appreciated....thanks
