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.

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