is ther something other than the coil or something that controls the coils on 1999 Mercedes-Benz ML320

what could be cutting the spark off so that it doesnt start?

Asked by for the 1999 Mercedes-Benz ML320
An anti theft system can prevent spark, a defective engine sensor such as a camshaft position sensor or crankshaft position sensor can contribute to lack of ignition spark. Wiring harness issues, fuses, bad electrical connections, relays or Electronic Control Unit problems can all effect spark.
how can i determine what it is since there are so many possiblilities
if one of the sensors fail will it give a code of some kind or check egnine light
