Are the ECU throwing any codes ? Apart from the things you listed you need the ECT sensor and the VSS to work for VTEC to activate.

The ECT sensor is the Engine coolant temp sensor. Itīs located under the distribitur if I remember correctly. It gives the ECU the engine temp so it knows when itīs up to operating temp. No ECT = no VTEC.
