Default no signal to injectors, wiring loom o.k.

diagnosing a no start condition (98 sl500) with good fuel pressure, good spark. will fire with starting fluid. It has good fuel pressure, good continuity from ecm harness to injectors, and good spark. there are no obdII codes, only a message "start error" and all mil's are on with key in run position. Could this be caused by the factory security device or is a failed ecm?
