Re: 1985 volvo 240 intermittent no spark ?

The last time I caught it not working, there appeared to still be continuity in the Hall sensor , The wiring harness is not great but Ok I thing with the only visible deterioration around the gray firewall connector which was repaired by stripping back and splice in new wire as necessary . Are there any other connection points ( other than the ECU plug, Coil terminals , distributor Hall sensor connections - has Bosch distributor ) to check in troubleshooting this sort of problem ? BTW- does this model have a separate ICU ( different from the ECU located near the windshield washer bottle ) , if so where is it ?

- thanks
