RE: VTEC issues
Is the CEL ON? If so, retrieve CEL code(s) from ECU as described in the link in my signature.
Not sure if you have an ECU mismatch. Did you use the 97 ECU from your car or the 98 ECU from the car that you got the engine?

RE: **** issues
Your ECU could be a mismatch but if the right one was in there before the swap, then it's the right one. It wouldn't hurt to check if you infact have the right one. Your ECU could be bad (this rarely happens). Is your VTEC solenoid wiring harness plugged in? Check and see it it's in there snug.

Post a photograph of the unidentified connector near the alternator. Someone may be able to tell you what it is.
Also post the specific fuel CEL code that was retrieved by advancedautoparts. This could potentially lead to a solution for the problem you are having.
