I just tested all the fuses yet again with a test light. probed both ends with test lamp. They are all ok. In any case none of them are labeled for ECU or anything close to engine management. I thought it was the OVP that powered the CIS. Also please note that i tested the connector to the CIS for ground and power and it was good, power is getting to the ECU (CIS).
