92 Prelude Motor Replaced

I recently replaced my Preludes motor with a motor from Japan. It is the 2.3 dual overhead cam. Now we can't get the check engine light to go off and it will not show a code from the computer. Has anyone ever had or heard of this happening and if you have what did you do to fix the problem?

Thanks for any info.

It may be there for a reason. Something on the motor could be bad.
Try resetting the ECU and see if it pops up again. If it does, maybe shoot down to a shop and hit up the computerized diagnostics..should be able to give yu a little more info then OBD

Not good with the abbreviations, but We have reset the computer and it still comes on. The motor was put in by a professional shop and they have a computerized diagnostic system and still didn't show any codes. What is ECU and OBD?

Thanks for your help.

ECU = electrical control unit (the computer that you already reset)
OBD = On-board diagnostics

Basically Mazdax is saying a shop with a diagnostic computer can tell you more than the minimal diagnostics available from your ECU.
