I've been searching without any luck on a post about a main relay conversion kit. So I'll just ask. I'm new, and do not know alot about the mechanical side just trying to learn. Is there a difference in main relay conversion kits? My main relay was a 7 pin connector but the conversion kit is 5 pin. Is there more than one kind of conversion kit? I purchased a 91 CRX drove it home on a 6 hour trip ran for a day and now won't start. From what I have read the main relay should be the first thing to try replacing. It cranks, but doesn't fire.
