hey i think i know what it is. ur vtec is not running.

do u know how to make a vtec light? if yes then make a vtec light and see if it turns on @ around 4k rpm.

if not, then put ur car on a lift and put it in D1 or first gear, disconnect the vtec solenoid and have someone give it gas and go up very slowly to 4k rpm. hook up a test light to the vtec wire coming from the ecu. and see if it lights up. if it lights up then i'd change out the vtec solinoid, because thats the only thing that could go wrong if the light comes on.

if not then ur wire probably broke some where.
