I just recently took my integra out of the garage for the new season and started driving it again. I did all the preperation of running it again and took it easy during the re-break in. Anyway now that it has some wear in and i started running it hard again vtec is not engaging. I know there are tons of threads on this but i searched and could not find anything that helped me with my problem.

The car is a 2001 ls/vtec turbo. With a 00 gsr head and the wiring harness adapter to plug in the obd I p28 ecu. I did work on teh car a bit while it was garaged without starting it. The car was not started for about 5 months.

Does anyone have an idea of what my problem can be?

 

maybe just change out ecu...with another..to see if vtec kicks in..

 

Thats not a bad idea but i would ned to either buy or find another one socketed with hondata.

Anyother ideas?

 

there are multipale reasons why vtec will not engage

low water temp
low oil level
low oil pressure
speed you are traveling

also check your signal wire, mine came loose before and I couldnt figure out why mine would not engage

 

Thanks i will check those things again. I know the water temp is fine and the oil evel and pressure is good. But i will double check the signal wire

 

any other weird reasons it wont engage?

 

Are you sure it's not engaging? I know it's a bit of stupid question to ask but I know on my lsvtec turbo I no longer feel the vtec engagement let alone hear it.

It was only until we put it on the dyno and saw it on a graph as well as hooked up a pressuage gauge to the head/solenoid itself that we saw it engaging.

did you take your head off? if so there is a little, i dont know what to call it exactly, but like a small dowel pin. it goes underneath the middle cam cap holder thinger haha. anyways, without that vtec will not engage.

No i understand the reason for your question. And i do agree with you, i know exactly what you are talking about. But the two big reasons for me not thinking it is engaging because the car is a lot slower than it was before the winter, like a very noticeable about. And it stops pulling after like 6500 rpm. It used to pull hard all the way to redline almost making me not even want to shift sometimes but now once it gets up high there isnt any point in waiting to redline just because it is no longer pulling or making any power

 

i am also going to try to go to radio shack tomarrow to buy some necessay adapters and cables to hook my mac to my hondata to be certain if it is engaging or not.

 

Any other clues?

Umm have you check the solenoid? Use a test light to see if there is signal going to it. If there is then you might need a new solenoid. Also check to see if you hear it clicking over inside the solenoid. Check your grounds.
