Lude Generation

Just so stumped, tried most things out that could of caused loss of vtec. Wondering if anyone has had this issue before?

I wouldn't have thought so, is it earthed on the chassis?

Are you sure the vtec solenoid is gettting a signal from the ecu? Wire in a bulb or buzzer just toi be 100%

Just solved my no vtec and was speedo. Worth a try.
Rule is up to temp or no go and over 18mph or no go so make sure
Ecu getting these signals......
