my crx decided not to start one day. main relay's new, fuel pump's working, fuel filter's new, getting sparks, new battery. anyone have an idea what might of went wrong? it was working fine, over a week then it stopped working. but also i pulled out the head unit during that week of not driving the car. but i checked my wires around the head unit and everything seems to be plugged in and the grounds. i also checked all fuses and battery terminals. so if anyone had the same problem or know what might of went wrong, please let me know. thanks.
