88 Integra code 9 Help!!

88 Integra spitting out a trouble Code 9. Did troubleshooting according to Haynes Manual, but all readings checked OK. Ohms between pins D & E of the crank sensor plug was 370 and no continuity between any pins and ground. What else could be going on here? Should I try a used distro. since all the sensors are in it despite the readings? Help!!
