00VI swap, 5th gen everything not turning over, suggestions please,

Well, spend all night swapping it in, no EGR because I could not get the dam guide tube off, blocked off both ends of that

Using 5th gen IACV

The motor just will not turn over, any thoughts are welcome

 

any clicking, radio/headlights work?

 

clicks, radio works

I pulled the codes I have a (0205) Idle Speed Control code

did i forget something using the Using 5th gen IACV?

 

Did you ground the engine harness real good?

 

yup! ill post some pics as* soon as I can find a darn camera

 

Only reason why it wouldnt crank at all would have to be because of the grounding situation, try grounding to another grounding spot(ie. timing cover)

 

sry, wrong word, its cranking, its just not starting

 

 

 

try holding the throttle open when starting the car? if the iacv isnt working correctly it may not start without holding the throttle open.

 

I dont see a vacuum line on the fuel damper? I would remove that 00IACV, and block off the hole it makes. Adjust the set screw after you get it to startup

 

it will not start at WOT

where is there a screw on the 00IACV?
ill go take it off and look

 

check for spark, check for fuel. thats always a good place to start...check your connections.

 

did you check the vacuum on the fuel line?

 

The 5th gen IACV isn't the greatest idea in the first place because it isn't 100% compatible with our ECU and wiring harness, it would seem. But, if holding the throttle open won't allow it to start, the IACV probably isn't the problem. Are you trying to start it WITH your intake attached or no?

 

yes, intake is on

 

What is the best way to check for fuel?

The rail is pressurize, I popped off one of the FPRs to see

 

Sniff the exhaust while someone else cranks it.

 

Title edited for clarity.

 

Ok I think it’s the fuel, the exhaust dose not have a gas odder, and when I crank the engine with my hand under the injector I don’t feel any mist, what could be wrong with them? The fuel line is pressurized I am going to check wires

 

ok well now I am not so sure about the fuel theory, after pulling the fuel pump fuse and cranking it for a little bit I was able to depressurize the fuel lines, if they were not working the fuel rail would have stayed pressurized, hmm

 

still no luck

is the fact that im using both of the 5th gen FPR a problem?

 

have you grounded the injectors...remember the little black wires that connected together in front of your usim. Check also the fuel delivery hoses if you changed all the hoses...

 

Blown fuse . . .now on to the air leaks

 

Ok it runs, at 0% throttle it accelerates to 35MPHs thos, In neutral it will climb up to 3k and drop back to 2k, so it sounds like there is a vacuum leak and the IACV is trying to compsate?

I switched to the 4th gen TPS, my VAFC reads the throttle % now,
Good news no more CELs!

So what’s the best way to look for vacuum leaks? Popular spots for 00VI swaps to leak form?

ill post if I find anything

 

Not sure if you read, but remove that 5G IACV and block off the TB where it attached to it. A 5G IACV doesnt really work correctly on this swap.

 

you suggest using the 4th gen IACV then??
who sells the plates for thos?

this thread says thet the 5th gen IACV will work

 

modded in the 4th gen iavc, still same problem dose this sound like a vacume leak? from where

I blocked off where the 5th gen iavc plugs in FYI

 

the surging idle sounds like a vac. leak, while the car is running spray carb cleaner at different spots to find out where it is leaking. When the engine takes in some of the car cleaner the rev's will race. Some of the more common places for them to leak is at the Lower and upper intake manifold unions.

 

yeah I think its the plenum gasket I ordered a new one , we will see wends

 

I'm using all 5th gen, including IAC- works perfectly in all conditions.
Be sure to properly adjust the TPS and base idle too.

 

Sorry bro, but i have to say you are using VERY OLD information... or you just don't know..

I've done 9 00vi installs! only 2 stuck with 4th gen IACV + adapter plates, and ONLY those two guys have cold start issues.. everybody else starts the car and it revs to 1500

I even had the Pathy TB + IACV on my Max hooked up and working CORRECTLY, the way it should

I'm not out to start BS.. just information for those who need it.

 

THX I am on it already, i am going to use the 5th gen IAC no matter what I have to do just to spite GTR_rider. I have read 4 threads about similar vacuum leaks and he says in all of them that the 5th gen IACV dose not work for us and that using the 4th gen Iacv will fix the problem. Maybe he can post that on his VQpower site

 

I stand corrected, also, then. Just curious, what are you doing to them to make them work? Just splicing wires?

 

The thread that RedfoxXx posted on the first page details what to do to use the A33 IACV.

 

Not that it's the cause of your problem, but here's something else you'll need to fix to get the 00VI working correctly: that vacuum line to the passenger-side port on the VIAS is wrong. That port doesn't need vacuum, which will cause your power valve to be activated continuously. That port should be connected to fresh, unpressurized air. On stock 5th gens it's connected to the airbox (IIRC); I don't have mine connected to anything.

 

Your right i miss read this thread http://forums.maxima.org/showthread.php?t=508217

THX!

 

All you do is break the outer connector shell part of the IACV on the engine harness side and than connect that the the 5g IACV. Use tape to hold it down.

ON the 4g IACV there's a pink and purple connector. This can actually be removed from the IACV. Take them off and find a place in the engine bay to tie them too. No splicing at all.
