Help! Vacuum line off of transmission after CAI install

[SlowStee]

I just installed an Injen cold air intake in the maxima, and when I was finished with it all there was still a vacuum line left. Ive gone through the directions over and over and it says nothing about this line!


The vacuum line seems to be coming off of the transmission ? the car wont start either.

Ill have a pic up in a few minutes here..



anyone help me??:(

[Car Guy]

Are you sure it's a vacuum line...?





:banana1: :banana1: :banana1:

[SlowStee]

here they are

[Car Guy]

It's hard to tell in the pics, get your old setup and see if there's a difference in the number on 'hookups'. Process of elimination in the best way to figure stuff like that out.....





:banana1: :banana1: :banana1:

[johnny--2k]

that's wierd. I would just go through the old connections on the factory intake as already mentioned. That's your best bet.

The only other thing I can think of is it's a vent tube for the trans. Don't hold me to it but I've had it happen to me before and now that I look at the pictures again I think that's it.....

could very well be, but that does not explain the car not starting? I know my old Benz had a vacuum controlled tranny and with my home-made (yeah yeah, whatever I was a kid) intake, it started messing with the tranny because there were two vent holes on the valve cover that were routed to the factory intake. Once it went back on, no more problems.

Is the maxima a stick or auto?

it's stick, in the instructions, all the pictures shown for the install are for an Auto too...I cant find SHIT on what this line is..

I didn't know there was a problem with not starting and being stick I don't know then, would have to get a look at it in person.....:confused



Have you driven it yet with the mystery line disconnected...???

no, it wont start up at all...it turns over but wont start

[johnny--2k]

thats definitely a vacuum line then. Did you try plugging it with something to see if it will at least start?

[Flight_740]

Plug it. It went to the factory airbox and is no longer used with the intake.

[Russ Jerome]

YR/Make/model/ engine and I can bring up a vac schematic
of your car right now while I am on my computer.

[Flight_740]

It actually looks like the fitting snapped off into the tube.

About the starting issue, you sure the Maf and intake temp sensor are plugged in?

[Yooformula]

plug it. i told you that already. tahts what i did with mine.

Sorry couldnt read the goofy color in his signature...oops.

Ok the RS5F50 transaxle does in fact use a steel breather
tube out top of the housing, it mates to a rubber hose
that does in fact go to the air filter. It should be visible
right on top of the transaxle (thru the clutter). Add a
nipple or simply "T" it into another vented, non vacuum
source so it see's clean air.

Not your no-start issue obviously.

yeah...I called Injen and they said that line just sits there and serves as a breather valve...so dont bother fussing with it..


HOWEVER..the car still wont start. Randy looked at at with me, and we cant figure out why the hell it wont start. Everything is connected, sensors all appear to be 100%, reset the ECU, and still wont start.. Cranks but wont start.


The car was 100% no problems before the install.

[Flight_740]

Did any pins break in the Maf conections?

Are the conections dirty?


The maf is the only thing you messed with that would cause the car not to run. Thats the only place I would look.


Nissan has very funky conectors. I actually had to zip tie my Maf plug when I replaced it. Put pressure on the plug when somebody is cranking it.

[theavenger333]

so take the intake off

[Russ Jerome]

Turn the MAF so it points the right way........ :o

[HP ADDICT]

MAF is pointed the right way. You can hear the IAC making some odd noises also when the key is turned. The only thing I can think of is the MAF issue mentioned above.

[Reverend Cooper]

you didnt happen to drop the maf or anything like that during removal or reinstall.
otherwise check the connector pins

[Silver03SRT]

that sucks. did you get the car to start yet?

[SlowStee]

Rob's on his way over...come on by!

[SlowStee]

Anyone ever hear of the Nissan Vehicle Immobilization System :chair: :chair: :flipoff2:

[Car Guy]

No, but fill us in cause it sounds like fun.....:durr





:banana1: :banana1: :banana1:

[johnny--2k]

WTF....are you serious?

[Flight_740]

Test your maf with a meter.

Maf voltage (power side Black and white wire) should be at 12v. 5V on the signal wire. (white wire) and the all black is ground.

Also, any codes stored? Let me know. I can swing by with the scan tool I have.


Did you mess with the TPS at all?


Edit: I just saw your post about the imobilizer, was that it? is it running now?

[HP ADDICT]

Julian 0 CAI 1

[theavenger333]

TAKE THE INTAKE OFF. if it doesn't start with all the stock stuff back on, then you bent some maf pins or something

The security system is tripped..It seems no fuel is being allowed to the engine. Calling the dealership in a few.

[lilws6]

does it have keyless entry? if so try and press both lock and unlock buttons at the same time and hold for a few sec. i did this with my cav and it fixed my no start security issue as well

yeah Ive got a few things to futz with before I call...The security light is definately staying on when the Key is in the on position though, Which according to the manual, is NOT supposed to happen if its disarmed.

[Flight_740]

Use the key to lock and unlock the doors.

[SlowStee]

Use the key to lock and unlock the doors.

have tried everything you could imagine. We've tested EVERYTHING with the intake and sensors too.


Im going to try to reprogram the Keyless entry device.

[SlowStee]

Had the car towed to the dealership, the Security system is in complete lockdown. It wont let them reprogram the key either. It has their scanner completely locked out of the system.


Great...no car this weekend...cant wait to see the bill!

damn dude that fukking sucks ass.....

[wikked]

Watch it's just a fuse (didn't see anyone mention fuses :P) :goof

[SlowStee]

Watch it's just a fuse (didn't see anyone mention fuses :P) :goof

we checked all that she-at

[hrsp]

update yet??

[SlowStee]

Dealership is closed on the weekends. lol :chair:

[SlowStee]

Dealership figured it out, the IMMU, which is the part of the ignition that reads the key, went bad. Cause? they don't. Most likely has nothing to do with the CAI install.



over $300 bucks to fix...the place where I bought it from is paying half of the total cost. I have NO car luck. :chair:

[Flight_740]

Well, I hope this does not spoil your thoughts on Nissan. Theyt really are great cars.
