i have a 93 civic ex and it wont start. there is no spark so i change the ignition coil and the igniter or ignition moduel and there is still no spark. i can hear the fuel pump run and there is power to the injector. i looked at the fuse and there all good. the only thing i havnt look at is the main relay but if that was bad, would there be no fuel too. any input will help.
