does anyone know how i can get my vtec to engage? its a b20 vtec..i hooked up everything right...it just wont pop..any help or suggestions?

 

are you using an ecu with vtec like a p72, p28 ?

 

its an obd 0 so i have a pr3 ecu thats a jdm b16 ecu and it is a vtec ecu

 

Hows your oil level? Speed sensor? Any CEL's?

You can always run a switched 12v to the vtec solinoid into the car and switch it on while driving. Just to test if the system actually works or not. If it works there then its something with the wiring or ecu making it not work... try to run a direct wire from the ecu pinout to the vtec solinoid if that doesnt work something is up with your ecu.

if you choose this method, make sure you have enough oil pressure to flip a vtec switch.

my advice is to chase wires, chances are that's where your problem lies. if that's not it start looking at things that are vtec specific to make sure everything is functional etc.

 

i had the same problem check your oil pressure and if not that its youre ECU thats what was wrong with mine
