I have a 95 honda civic, 1.6 vtec.for 6 days now I have done the checks and rechecked the checks until I don't know where I am going next. On the large plug to the distributor should the yel/grn wire be showing continuity to grnd? And, how can I check the main relay. I hear fuel pump, then click, and one more click. Cel goes out unless I jumper the diagnostic port. Then it stays on. Is that a code 0?? I would really appreciate some help. Thanks J.C.
