s14 with s13 SR....no spark. Anyway, ecu is throwing a code 11 (only code 11) and I began the diagnostic procedure according to the FSM. Part A on EC-111, the power supply check, passed. On EC-111 in the FSM, under inspection start B, it says to test the ground circuit by turning the igntion off, loosening and retightening ground screws, and checking the harness for continuity between terminal A of the CAS plug and the engine ground. I tested multiple grounds (2 on back side of intake manifold, the large one on intake manifold to chassis, the ground by the radiator, and the alternator ground. The average reading of ohms was 1.3-1.5...indicating no continuity. To remedy this, the FSM says to repair harness or connectors.

Where should I begin repairing the harness or connectors? The CAS plug is in good condition and fully clicks into place...

EDIT: the CAS is getting power, the voltage fluctuates between .1v and 5 v just like the FSM states.
