Anyone please help! I have a 94 accord which I haven't had any problems out of until it rained one day, it started running rough then died and hasn't started since. I found where some people have changed the main relay and fixed similar problem. The d4 light starts flashing when you turn the key on but doesn't seem to be flashing any codes it just flashes until you turn the key off. Is there a way to get codes specifically from the tcu? I see on posts where folks are getting tcu codes from the flashing d4 but am at a loss as to how to get them myself. Do you use the 2 pin connector behind the glove box or is there another way. I desperately need suggestions please. I need this car running quick and can't afford to take it to a shop.
