GREETINGS...THIS 960 HAS NO INJECTOR PULSE/NO IGNITION PULSE. HAS CODE 1-3-1 FOR NO RPM SIGNAL. HAVE SCOPED RPM SIGNAL AT CRANK SENSOR AND AT ECM AND IT IS PRESENT AND PROPER. OHMS TESETED CRANK SENSOR - OK AT 320 OHMS. TESTED BOTH WIRES FROM CKP SENSOR TO ECM FOR CONTINUITY AND THEY ARE BOTH GOOD. TRIED A KNOWN GOOD ECM AND NO CHANGE.
