check your oil, after that start checkin your wiring.

 

do you have oil in the motor?
is your speedo working?
Is your temp gauge working

 

yea i just did a oil change. but my temp gauge is messed up i think

 

What are you running for an ECU?

 

i think p28

 

you are has to warm up for the vtec to work.. if it don;t know what tempture your car is it will not engage

 

check your grounds

factory engine?
