i have a 00 civic si, first of all the problem i had was i was getting no spark for the ignition, everything (literally) checked fine, so i replaced the coil because those go first usually, and it started up fine... that was 2 days ago.
today my check engine light came back on and wouldn't start yet again, i checked again and i was getting no spark... yet again.
i'm not sure what would make the coil go bad that fast or if something else would cause this to happen. i've checked wires, ignition control, alternator, battery, and plugs. everything seems to be in good order.
if anyone can help please reply or shoot me an e-mail.
thanks
