YOu prob wired it up wrong! Double check and tripple check your wiring. Make sure the solenoid is grounded and if you want to make sure it works you can unplug the solenoid from its connect clips and and run a small wire directly to the battery or any constant power source and just tap it with the wire.... if done correctly you should hear a *click* from the soleniod if it is working properly! That means your vtec just clicked in yo! Lol.

btw make sure you do this while the car is off and be sure your wires are grounded so you dont blow something up!
