Hi, I know this has been brought up before, but of all the posts I've read, I still can't find the fix for my car. I have a 1991 Civic LX 1.5L that is spitting an error code 15 (ignition output signal) and I can't figure out how to fix it. I have tested the ignition coil, it's good, replaced a bad igniter, replaced the main relay, but it still won't start. it turns over, just doesn't start. I am not getting spark to the plugs, but have replaced everything I can think of that would fix it. does anyone have any idea what could be the problem/solution? Thanks.
