check the small things first, make sure you have enough oil in the motor, if so take the vtec solenoid off check to make sure the screens aren't clogged, then check connections to the ecu.


what kind of ecu are you running?

does your speedo work?

make sure you top off the vtec fluid also

^ ^ What he said. Also sometimes vtec will kick in but it won't be as hard as other cars. You can test the solenoid to make sure its working as well

put a test light on your vtec solenoid and drive. See if it lights up while driving in VTEC.
