the engine light could be there for something else. but also the solenoid may be siezed.

well check engine light was not on before i did the wiring for vtec. after that, it came on, and how do i know if the solenoid is you said seized and how do i fix it?

what code are you getting?
Many codes will stop vtec from working.
Vtec looks for an oil pressure signal, a RPM signal, a VSS (vehicle speed sensor) signal, a ECT (engine coolant temperature) signal.

Figure out what codes your getting, fix them if they're important for vtec, then you should be good to go.
To check if the solenoid is ok, send 12V to the solenoid, it will click and you will hear it click as you give it 12V, if not, get a new one.

For some reason im thinking its the VSS for him. Happened to my brothers car and my 1st civic.

anyways, always check your check light when it comes on. Chances are, that's your problem
