i have a 93 300e and recently all of a sudden the car want start. It will turn over but not start. Before this happened it ranned fine. I replaced the plugs and wires and it ranned good up until now. I tested to see if the plugs were getting wet and they were but no fire. I checked the fuel pump and its fine. Also the battery is good. I called the Mercedes dealer to see if all three coil packs would go out at the same time, he said no.
Please HELP
