I would check for power at the injectors and on the other wire check for pulsed ground as the engine is cranked over. If either of these are missing the cause will need to be determined. It could have a wiring issue with power or ground supplies to the PCM, a bad input to the PCM such as a missing crankshaft signal, or a bad PCM. Further testing will be required to pinpoint the problem.
