I need some help!

I have a 1985 380SL that was made in Germany and shiped to the U.S. I got the car from my uncle, so this is the first Benz I have ever owned. The car ran perfect the other day when I parked it. I got in and tried to start it, but it just turns over. I then opened the hood to investigate and this is what I have:

First I checked for fuel delivery on the fuel rail and found pressure. I can also hear the fuel pump operate. I checked for spark, which there was none. I checked the coil, primary side has voltage, secondary side has just enough to illuminate the test light with the engine turning over. I checked all of the fuses, also re-seated all of the relays, still nothing. I tried using other keys, disconnecting the battery. As for a security system, the car has a factory installed digi keypad which you type in a code to arm/disarm the system. When the system is alarming the ignition is cut, so you can not turn over the engine. Once reset you can turn over the engine.

Any help on this would be greatly appriciated. Since this is my first Mercedes, I do not have any technical knowledge about this car.
