Did the check engine light come on? If not, then there's no codes.

There is no port for a reader, just a connector behind the radio that you have to short out which causes the check engine light to flash. Number of flashes = the code.

This isn't the best source of information, honestly. I recommend you also sign up for PreludePower.com and Honda-Tech.com.

From my experience, there is more valuable information on this forum than the other prelude forums, but it takes a while to find it. The original members on here knew their stuff before they went into hiding in OT. I just start with the oldest threads and work my way towards the newer ones when I search, because most of the new threads suck. The dead links and missing pictures are a real pain though.....
