wat up guys i just fixed all my check engine light, due to code 14,10,21 and 6 my vtec should kick in but it doesnt i know my vtec selenoid works cause i alreaddy test it and it does click, i have a virgin pr3 ECU in my car, do you guys have any ideas about what could be wrong with it??

i would really preciate yourguys help thanx

 

what is your set up? who wired it up for you?

 

igot a 94 gsr in it
i got the car like this but it had a **** load of check engines codes but i already fixed them i am not that pro at this **** my check engine light is off for now but vtec wil still not kick in

 

does it burn oil??

 

no the guy who i got it from just rebuilted the engine probly has around 16k miles on it

 

hmmmmmm

 

has it ever worked for you?

if not then maybe it never worked and you got ripped off?


just a thought

dude vtec does work i got the car for free from my unlce he bought if off an auction i know vtec works cause ive been running it with a switch

 

thanx dude let me try to set this thing up

 

You used a switch to make vtec work, wow hella smart man. Try putting cars together right before ghetto rigging it

 

VTAAAAAAAAAAAAAAAAAAK!

 

X2 !!!

 

seems to me you answered your own question. your vtec set up was never hooked up/wired in to work. especially since its being ran to a switch which is activated by shooting power to it. wire it up directly to the ecu, then let us know after its wired correctly

 

i had similar codes on my hatch and afer working out the wiring gremlins it work great

 

i already hooked up everything my check engine is off, but still it wont kick in
do you guys think it may be cause the oil pressure aint good?? cause the oil pan looks a lil bent due to the car is low as ****

 

if the selenoid works and everything is wired correctly then vtec should engage. You are gonna do more damage running it with a switch, not to mention flipping a switch at high RPM is quite dangerous. The usual suspect when vtec does not engage is low oil pressure. CHeck your levels and pressure before you do any further harm. Check your grounds also.

 

VTEC will not work if you are low on oil as well, just a thought...

 

make sure u have a good tach signal going to the ecu

 

do you have enough oil pressure?

 

i dont know yet im about to install an oil pressure gauge, do you have any idea about how many oil pressure am i supossed to have or should be ok so it would work?

 

hey, sry to hi-jack this thread but im having a similar problem, i am running an 89 std hatch, w/ b16a obd-0 swap, it has always run great, about a month ago i snapped the speedo cable ran around a couple weeks without it, but when i replaced it, vtec randomly works and when it does only for a few seconds. also my rev limit has dropped from 8200 rpm, to like 7800 rpm. i have no cel, or ecu codes. ive checked all my wiring, ive checked the solenoid, any ideas? i need my vtec!!!
