I just finished my 00vi swap and now the car doesn't turn over.
Its not a vacuum leak cause you can hear air being suck through the intake and the iac motor is actually working.
Normally I would have a spark issue but I would smell fuel. This time I didn't.
So I checked for spark by removing one of the coils inserting a spark plug and letting it touch ground.
I didn't get any spark.
I checked for fuel I removed one of the harness off for the injector inserted a led bulb amd cranked the car. The light only flashed one time and that
Was it.
The injectors connector I removed off of the 5th gen the one with a line through the middle of the wire I assume is the negative while solid color is postive.

That's how I hooked it up. I don't know what else it could be...please help

Anyone? ???

 

Since you have a 99 I30T maybe you tripped the NATs somehow? Is the security light on solid?
Also, you say doesn't turn over. That sounds like a dead battery condition, but the engine is turning over because of those vacuum observations you made.

So I gather whats happening is that the engine is turning over but not firing, and you see no spark and smell no fuel, correct?

Also, is your 00Vi with 5th gen fuel rail and injectors?

 

Yea the 00vi has 5th gen injectors.
Battery is fully charged.
I didn't bother to look at the nvats light cause I never had a problem with it before.
I switched out the injector harness connectors. I was assuming the one wires with a line in the middle was ground while the solid color wires were positive.
Also the ground I ran from the negative battery cable to the little ground junction wire that was normally on the aluminum intake. But still no start.

The security light isn't solid

Okay so I got her up amd running. Remember people ground is nissans ecu friends!!!
So now the problem I'm having is after a few minutes of running the rpms would gradually raise up amd bounce in between 1400-1700rpms. ...

I think I may have a defective iac????

Anyone?

 

Try spraying the MAF and the IACV harness connectors with electrical cleaner ($4 at walmart). That fixed my bouncy idle last time I took **** apart... and didn't even replace IACV or MAF

 

Hmm...the maf I replaced recently due to performance issue at high rpms.
I suppose I could try to clean the iac harness.
I noticed that on the iac valve there's a little flap with a spring of some sort on the inside In the way of the iac valve airway...do the 00/01 have fast idle control...

 

What does the car act like when its cold, and how does it act when it has warmed up properly, like driven for 30+ minutes?

 

With the iac connected it would would rev at 1500 rpms then go down to 1000rpms after a couple minutes then it'll start to idle up then bouce between 1400-1700.
I don't have the coolant hoses connected to the iac...as stated before I think they have some sort of cold idle system.

 

Then I shut the car off unplugged the tps sensor started her back up amd the rpms shot up to 3k.

 

With 5th gen injectors you have to have an management computer like E-manage to tame the beefier than stock injectors. Have you done so? Also, if you have never replaced your O2 sensors, replace the primary O2s. Tired sensors give non-optimal reading and will not trigger the check engine light.

 

Haven't tuned yet because of the idle issue.
There's no vacuum leaks...
I tried adjusting the tps and still the same thing.
Im so lost...

 

Are you using a 5th gen TB and IACV? 5th gen IACV are "Iffy at best" (taken from numerous 00VI write ups) when used as part of the 00VI swap.

 

Yes I'm using the 5th gen iac.
The write up said our cars can use this.

 

While it is true that you can use a 5th gen IACV with the 00VI swap, the 4th gen ECU likes the design and function of the 4th gen IACV.

 

So the bouncing up and down rpm is due to the 5th gen iac valve.
There was a you tube video of a maxima with s swap and his turned out good.

 

So...I was doing some searching and came across this.
This is exactly what my car is doing.

 

So today since its hot out what the car has been doing is starting up. Idling normally then about a minute or three later it'll start to rev up to 1500 rpms.

Yesterday it was bouncing up and down but today it hasn't done it.

I'm losing my mind here...please help

 

Bump

 

Bump...anyone? ??????

 

????????

 

So what you're saying is that you're using your 4th gen TB with 5th gen IACV?

Since you probably still have your 4th gen IACV, I suggest you install it.

No. Everything is from a 5th gen. Even the throttle body and iac valve.
When i was searching there were people who used the 5th gen iac and tb and their car is fine.

 

Bump

 

So I was able to mess around with the car today.
Here's what I did.
So I removed the iac valve start the car up and quickly put my finger in the intake port where the valve goes. The thing wanted to shut right off. Unless I had the throttle slightly open.

I put the old iac back in.
I idles at 800rpms in gear with the ac on.
1000rpms with the ac off while in gear.
In park doesn't matter if the ac is on or not 1500rpms.

 

Sooo...this morning got up. Started her up. Was idling around 700rpms.
Idling like crap. None the less it was idling.
Then three minutes later it shot up too 900rpms.
Then about a minute or two later I start to hear this suction noise from my cai and the idle started raising up.

 

Anyone please?

 

I gave you the answer..... twice already.

SMH

 

And I already told you twice. SMDH.
if there's other 4gens that has the full 00 set up and its running fine, I should be able to also.
