hey guys i got a lil problem that i cant figure out.. first my speedo is not working can that be the cause of my vtec not popping? other than that i gave the solenoid some 12v and it click so i dont think is bad... i wired up vtec to tha ecu and my check engine light when off while at idle when i tried to drive as soon as i probably hit 10mph the check engine light when on and no vtec.. i was also unsuccessful to get vtec to pop with a swich can somebody help me??.. ive been driving my hatch for a couple of months now and i still have not heard my vtec pop... every body that helps will be rep'd... thanks in advance...

oh its a d16z6 obd-1 on a 1993 hatch not pre wired for vtec...
