My car isn't starting up now, and I think it may be the main relay finally going out, but the engine code is 15, Ignition Output Signal. Anyone know what would cause an insufficient ignition output signal? Would a bad main relay contribute to that? I've got an '88 Si 4ws. Thanks.

it could be. im guessing you've already checked the distributor and that jazz?

I went ahead and replaced the Main Relay, and reset the ECU codes. The car runs fine now and isn't showing anymore codes. So I guess that was it. Thanks for the reply.
